    Priority Claim
    [0001] The present patent application claims the benefits of provisional US patent application No. 61/253,796 entitled "Uplink multi-power amplifier/antenna operation and channel prioritization", filed on October 21, 2009, and assigned to the assignee of this application and expressly incorporated herein by reference. Fundamentals Field
    [0002] Certain aspects of the present description generally refer to wireless communication and, more particularly, to a method of controlling transmission power and prioritizing transmission carriers. Fundamentals
    [0003] Wireless communication systems are widely developed to provide various types of communication content such as voice, data and so on. These systems can be multiple access systems capable of supporting communication with multiple users by sharing available system resources (eg Bandwidth and transmission power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Long Term Evolution systems (LTE) of the 3rd Partnership Project Generation (3GPP), Advanced Long Term Evolution (LTE-A) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems.
    [0004] Generally, a wireless multiple access communication system can simultaneously support communication to multiple wireless terminals. Each terminal communicates with one or more base stations through transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from the base stations to the terminals, and the reverse link (or uplink) refers to the communication link from the terminals to the base stations. This communication link can be established through a single-in, single-out, multiple-in and single-out, or multiple-in and multiple-out (MIMO) system.
    [0005] A MIMO system employs multiple transmit antennas (NT) and multiple receive antennas (NR) for data transmission. A MIMO channel formed by NT transmitting antennas and NR receiving antennas can be decomposed into NS independent channels, which are also referred to as spatial channels, where NS<min {NT, NR}. Each of the independent NS channels corresponds to a dimension. The MIMO system can provide improved performance (eg, greater throughput and/or greater reliability) if the additional dimensions created by multiple transmit and receive antennas are utilized.
    [0006] A MIMO system supports time division duplex (TDD) and frequency division duplex (FDD) systems. In a TDD system, the forward and reverse link transmissions are both in the same frequency region so that the principle of reciprocity allows estimation of the forward link channel from the reverse link channel. This allows the access point to extract the transmit beamforming gain on the direct link when multiple antennas are available at the access point.
    [0007] Additionally, the terminals can communicate with the base stations through one or more frequency carriers. As described, channels can be logically defined through one or more carriers for transmitting certain types of data, such as data channels, which can be shared between terminals, control channels, and/or the like. Control data sent through control channels can relate to the quality of communication through one or more data channels, including error correction data (such as an automatic hybrid request/repeat (HARQ)), quality indicators channel (CQI), matrix indicator precoding (PMI), rating indicator (RI) and/or similar. HARQ or other error correction data, for example, may include transmitting an acknowledgment (ACK) or negative acknowledgment (NACK) of successful reception of communications over a data channel. For example, where NACK is received for a communication, the sender can retransmit all or part of the communication to ensure successful receipt. summary
    [0008] Certain aspects of the present description provide a method for wireless communication. The method generally includes determining a prioritization of a collection of carriers allocated to transmit wireless signals, adjusting the transmit power for a plurality of carriers in the collection of carriers according to the prioritization, and transmitting signals over one or more of the carriers using one or more antennas according to the transmit power.
    [0009] Certain aspects of the present description provide an apparatus for wireless communication. The apparatus generally includes at least one processor, and a memory coupled to at least one processor, where the at least one processor is configured to determine a prioritization of a collection of carriers allocated to transmit wireless signals, adjust the transmission power to a plurality of carriers in the collection of carriers according to prioritization, and transmitting signals over one or more of the carriers using one or more antennas according to the transmit power.

    [0023] Various aspects of the description are described more fully below with reference to the accompanying drawings. This description can, however, be embodied in many different forms and should not be considered limited to any specific structure or function presented by this entire description. Rather, these aspects are provided so that this description is thorough and complete, and fully carries the scope of the description to those skilled in the art. Based on the teachings presented herein, those skilled in the art should appreciate that the scope of the description should cover any aspect of the description described herein, whether implemented independently of or in combination with any other aspect of the description. For example, an apparatus can be implemented or a method can be practiced using any number of aspects presented here. Additionally, the scope of the description shall cover such apparatus or method that is practiced using another structure, functionality, or structure and functionality in addition to or in addition to the various aspects of the description presented here. It is to be understood that any aspect of the description described herein may be substantiated by one or more elements of a claim.
    [0024] The term "illustrative" is used here to mean "serving as an example, case or illustration". Any aspect described herein as "illustrative" is not necessarily to be regarded as preferred or advantageous over other aspects.
    [0025] Although particular aspects are described here, many variations and permutations of these aspects are within the scope of the description. Although some benefits and advantages of preferred aspects are mentioned, the scope of the description should not be limited to particular benefits, uses or objectives. Rather, aspects of the description should be broadly applicable to different wireless technologies, system configurations, networks, and transmission protocols, some of which are illustrated by way of example in the figures and in the following description of preferred aspects. The detailed description and drawings are merely illustrative of the description rather than limiting, the scope of the description being defined by the appended claims and their equivalents. Illustrative Wireless Communication System
    [0026] The techniques described here can be used for various wireless communication networks such as CDMA networks, TDMA networks, FDMA networks, OFDMA networks, single-carrier FDMA networks (SC-FDMA), etc. The terms "networks" and "systems" are often used interchangeably. A CDMA network can implement a radio technology such as Universal Terrestrial Radio Access (UTRA), CDMA2000, etc. UTRA includes Broadband CDMA (W-CDMA), and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement a radio technology such as the Global System for Mobile Communications (GSM). An OFDMA network can implement a radio technology such as Evolved UTRA (E-UTRA), IEE 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM®, etc. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunication System (UMTS). LTE and LTE-A are future versions of UMTS that use E-UTRA. UTRA, E-UTRA, GSM, UMTS, LTE and LTE-A are described in documents from an organization called "3rd Generation Partnership Project" (3GPP). CDMA2000 is described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies are described below for LTE-A, and LTE-A terminology is used in much of the description below.
    [0027] SC-FDMA is a transmission technique that uses single carrier modulation on a transmitter side and frequency domain equalization on a receiver side. SC-FDMA has similar performance and essentially the same overall complexity as the OFDMA system. However, the SC-FDMA signal has a lower peak-to-average power ratio (PAPR) due to its inherent unique carrier structure. SC-FDMA has drawn a lot of attention, especially in uplink communications where a lower PAPR greatly benefits the mobile terminal in terms of transmission power efficiency. It is currently a working consideration for the uplink multiple access scheme in LTE, LTE-A 3GPP and Evolved UTRA.
    [0028] An access point (AP) may comprise, be implemented as or known as Node B, Radio Network Controller (RNC), eNodeB (eNB), Base Station Controller (BSC), Base Transceiver Station (BTS) , Base Station (BS), Transceiver Function (TF), Radio Router, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Radio Base Station (RBS), or some other terminology.
    [0029] An access terminal (AT) may comprise, be implemented as, or known as an access terminal, a subscriber station, a subscriber unit, a mobile station, a remote station, a remote terminal, a subscriber terminal. user, a user agent, a user device, a UE, a user station, or some other terminology. In some implementations, an access terminal may comprise a cell phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local circuit station (WLL), a personal digital assistant (PDA), a handheld device having wireless capability, a Station (STA), or some other suitable processing device connected to a wireless modem. Accordingly, one or more aspects taught here may be incorporated into a telephone (eg a cell phone or smart phone), a computer (eg a laptop), a portable communication device, a portable computing device ( for example, a personal data assistant), an entertainment device (for example, a music or video device, or a satellite radio), a global positioning system device, or any other suitable device that is configured to communicate through a wireless or wired medium. In some respects the node is a wireless node. Such a wireless node can provide, for example, connectivity to a network (for example, a wide area network such as the Internet or a cellular network) via a wired or wireless communication link.
    [0030] Referring to Fig. 1, a multiple access communication system according to an aspect is illustrated. An access point 100 (AP) may include multiple groups of antennas, one group including antennas 104 and 106, another group including antennas 108 and 110, and an additional group including antennas 112 and 114. In Figure 1, only two antennas are illustrated. for each antenna group, however, more or less antennas can be used for each antenna group. Access terminal 116 (AT) may be in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to access terminal 116 over forward link 120 and receive information from access terminal 116 over reverse link 118. Access terminal 122 may be in communication with antennas 106 and 108 where antennas 106 and 108 transmit information to access terminal 122 over forward link 126 and receive information from access terminal 122 over reverse link 124. In an FDD system, communication links 118, 120, 124 and 126 can use different frequencies for communication. For example, forward link 120 may use a different frequency than reverse link 118.
    [0031] Each group of antennas and/or the area in which they are designed to communicate is often referred to as an access point sector. In one aspect of the present description, each group of antennas may be designed to communicate with access terminals in a sector of the areas covered by access point 100.
    [0032] In communication via the forward links 120 and 126, the transmitting antennas of the access point 100 can use beamforming in order to improve the signal-to-noise ratio of the forward links to different access terminals 116 and 124 In addition, an access point using beamforming to transmit to access terminals spread randomly across its coverage causes less interference to access terminals in neighboring cells than an access point transmitting through a single antenna for all your access terminals.
    [0033] Figure 2 illustrates a block diagram of an aspect of a transmitter system 210 (also known as an access point) and a receiving system 250 (also known as an access terminal) in a MIMO 200 system. , traffic data for various data streams is provided from a data source 212 to a transmission data processor (TX) 214.
    [0034] In one aspect of the present description, each data stream may be transmitted through a respective transmit antenna. The TX data processor 214 formats, encodes, and interleaves the traffic data for each data stream based on a particular encoding scheme selected for that data stream to provide encoded data.
    [0035] The encoded data for each data stream can be multiplexed with pilot data using OFDM techniques. Pilot data is typically a known data pattern that is processed in a known manner and can be used in the receiving system to estimate the channel response. The multiplexed and encoded pilot data for each data sequence is then modulated (ie, symbol-mapped) based on a particular modulation scheme (eg, BPSK, QSPK, M-PSK or M-QAM) selected for that sequence. to provide modulation symbols. The data rate, encoding, and modulation for each data stream can be determined by instructions performed by processor 230.
    [0036] The modulation symbols for all data sequences are then provided to a MIMO TX 220 processor, which can further process the modulation symbols (eg for OFDM). The MIMO processor TX 220 then provides NT modulation symbol sequences to NT transmitters (TMTR) 222a through 222t. In certain aspects of the present description, the MIMO TX processor 220 applies the beamforming weights to the data stream symbols and to the antenna from which the symbol is being transmitted.
    [0037] Each transmitter 222 receives and processes a respective symbol sequence to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signals to provide a modulated signal suitable for transmission over the channel. PIM. NT modulated signals from transmitters 222a to 222t are then transmitted from NT antennas 224a to 224t, respectively.
    [0038] In the receiver system 250, the transmitted modulated signals can be received by NR antennas 252a to 252r and the signal received from each antenna 252 can be provided to a respective receiver (RCVR) 254a to 254r. Each receiver 254 may condition (e.g., filters, amplifies, and downconverts) a respective received signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding "received" symbol sequence.
    [0039] An RX data processor 260 then receives and processes the NR symbol sequences received from NR receivers 254 based on a particular receiver processing technique to provide NT "detected" symbol sequences. RX data processor 260 then demodulates, deinterleaves, and decodes each detected symbol sequence to retrieve traffic data for the data sequence. Processing by data processor RX 260 may be complementary to that performed by MIMO processor TX 220 and data processor TX 214 in transmitter system 210.
    [0040] A processor 270 periodically determines which precoding matrix to use. Processor 270 formulates a reverse link message comprising an array index part and a rank value part. The reverse link message may comprise various types of information regarding the communication link and/or the received data stream. The reverse link message is then processed by a TX data processor 238, which also receives traffic data for various data streams from a data source 236, modulated by a modulator 280, conditioned by transmitters 254a to 254r, and transmitted back to the transmitter system 210.
    [0041] In the transmitter system 210, the modulated signals from the receiver system 250 are received by antennas 224, conditioned by receivers 222, demodulated by a demodulator 240 and processed by an RX data processor 242 to extract the reverse link message transmitted by the system receiver 250. Processor 230 then determines which precoding matrix to use to determine the beamforming weights, and then processes the extracted message.
    [0042] Figure 3 illustrates various components that can be used in a wireless device 302 that can be employed within the wireless communication system from Figure 1. The wireless device 302 is an example of a device that can be configured to implement the various methods described here. Wireless device 302 may be an access point 100 of Fig. 1 or any of the access terminals 116, 122.
    [0043] The wireless device 302 may include a processor 304 that controls the operation of the wireless device 302. The processor 304 may also be referred to as a central processing unit (CPU). Memory 306, which may include both read-only memory (ROM) and random access memory (RAM), provides instructions and data to the 304 processor. A portion of memory 306 may also include non-volatile random access memory (NVRAM). ). Processor 304 typically performs logic and arithmetic operations based on program instructions stored within memory 306. Instructions in memory 306 may be executable to implement the methods described herein.
    [0044] The wireless device 302 may also include a housing 308 which may include a transmitter 310 and a receiver 312 to allow transmission and reception of data between the wireless device 302 and a remote location. Transmitter 310 and receiver 312 may be combined into a transceiver 314. A single transmit antenna or a plurality of transmit antennas 316 may be attached to housing 308 and electrically coupled to transceiver 314. Wireless device 302 may also include multiple transmitters (not shown), multiple receivers, and multiple transceivers.
    [0045] Wireless device 302 may also include a signal detector 318 that may be used in an effort to detect and quantify the level of signals received by transceiver 314. Signal detector 318 may detect such signals as total energy, energy per subcarrier per symbol, power spectral density, and other signals. Wireless device 302 may also include a digital signal processor (DSP) 320 for use in signal processing.
    [0046] The various components of wireless device 302 can be coupled by a bus system 322, which can include a power bus, a control signal bus, and a status signal bus in addition to a data bus .
    [0047] In an aspect of the present description, the logical wireless communication channels can be classified into control channels and traffic channels. The logical control channels may comprise a Broadcast Control Channel (BCCH) which is a downlink channel (DL) for broadcasting system control information. A Paging Control Channel (PCCH) is a logical DL control channel that transfers paging information. A Multicast Control Channel (MCCH) is a point-to-multipoint logical DL control channel used to transmit Multicast Multicast Service (MBMS) scheduling and control information to one or more Multicast Traffic Channels ( MTCHs). Generally, after establishing the Radio Resource Control (RRC) connection, MCCH can only be used by user terminals receiving MBMS. A Dedicated Control Channel (DCCH) is a point-to-point bidirectional logical control channel that transmits dedicated control information and is used by user terminals having an RRC connection. Logical traffic channels may comprise a Dedicated Traffic Channel (DTCH) which is a dedicated point-to-point bidirectional channel to a user terminal for the transfer of user information. Additionally, the logical traffic channels may comprise a Multicast Traffic Channel (MTCH), which is a point-to-multipoint DL channel for transmitting traffic data.
    [0048] Transport channels can be classified into DL and UL channels. DL transport channels may comprise a Broadcast Channel (BCH), a Downlink Shared Data Channel (DL-SDCH) and a Paging Channel (PCH). The PCH can be used to support power savings at the user terminal (ie, discontinuous reception cycle (DRX) can be indicated to the user terminal over the network), spread across the entire cell and mapped to the resources of physical layer (PHY) that can be used for other control/traffic channels. UL transport channels may comprise a Random Access Channel (RACH), a Request Channel (REQCH), an Uplink Shared Data Channel (UL-SDCH) and a plurality of PHY channels.
    [0049] PHY channels can comprise a set of DL channels and UL channels. PHY DL channels can understand; Common Pilot Channel (CPICH), Synchronization Channel (SCH), Common Control Channel (CCCH), Shared DL Control Channel (SDCCH), Multicast Control Channel (MCCH), Shared UL Designation Channel (SUACH), Channel Acknowledgment Channel (ACKCH), DL Physical Shared Data Channel (DL-PSDCH), UL Power Control Channel (UPCCH), Paging Indicator Channel (PICH), and Load Indicator Channel (LICH). UL PHY channels may comprise: Physical Random Access Channel (PRACH), Channel Quality Indicator Channel (CQICH), Acknowledgment Channel (ACKCH), Antenna Subset Indicator Channel (ASICH), Shared Request Channel (SREQCH) , UL Physical Shared Data Channel (UL-PSDCH), and Broadcast Pilot Channel (BPICH).
    [0050] In one aspect, a channel structure is provided and preserves the low PAPR properties (at any time, the channel is contiguous or evenly spaced in frequency) of a single-carrier waveform.
    [0051] The UL LTE-A design may allow exceptions for the preservation of single-carrier ownership of UL transmissions. Examples of UL transmissions may include transmissions over reverse links 118 and 124 in Fig. 1, transmissions from access terminal 250 to system 210 in Fig. 2, and/or transmissions from wireless device 302 in Fig. 3 to a base station associated. In LTE version 8 (Rel-8), where an UL waveform can be strictly based on SC-FDMA, simultaneous PHY channels can be eliminated in order to preserve the single-carrier (SC) property of the UL transmission. In LTE-A, PHY channels may not be eliminated unless a maximum transmit power is reached. Channel elimination and/or power scaling can be performed only if a composite transmit power exceeds the maximum available transmit power.
    [0052] Depending on an operational regime of the UE, it may be desirable to preserve the SC property of each of the PAs used and/or antennas that can be associated with the PAs of the UE. A subset of PAs can be used up to their maximum transmit power, while the rest of the PAs can be turned off. The same information can be transmitted on all APs/antennas. In one aspect of the present description, the PA transmit power can be filled with more than one channel, if this is necessary and possible. In that case, the SC property of UL transmissions can be broken. In one aspect, the PA transmit power can be populated according to channel prioritization.
    [0053] Certain aspects of the present description support a method of distributing power for PUCCH and PUSCH via multicarrier in the case of a power-limited UL. UE operating modes with single and multiple APs/antennas can be supported. Power Control and Channel Prioritization
    [0054] According to the aspects described here, wireless devices can prioritize the carriers for transmission and power control through the carriers. For example, high priority data can be transmitted over high priority carriers at increased power. Lower priority data can be transmitted in a lower power retransmission, eg automatic hybrid request/repeat (HARQ) or in other error correction techniques to ensure efficient transmission.
    [0055] In one aspect, carrier priorities can be defined by a wireless network specification. In another aspect, a UE may select high priority carriers among the UL carriers scheduled to transmit high priority data. Therefore, in a case of limited power, the UE can prioritize one carrier (or possibly more carriers) and transmit on the same high priority data that does not tolerate delay, while the rest can be based on HARQ.
    [0056] This approach may not deviate from the Rel-8 concept. For example, the Rel-8 schedule may specify only designated resources, which may not be specific to different traffic flows that the UE may have. Therefore, although the programmer can provide a designation considering the specific number of bits taken from the specific streams on specific carriers, the UE can use the designation determined differently. This may be true even if the same algorithm is applied to the UE and the programmer side, due to possible differences in storage situation. Additionally, the interpretation of how to use the resources designated through flows can be different.
    [0057] Thus, if the UE is power-limited by getting assignments on multiple carriers and has high priority data scheduled for transmission, then the UE can transmit that data with as much power as it can (or needs) on one of its assignments, and may deprive other carrier transmissions. Whatever the carrier (for high priority data transmission), the carrier can effectively become the "high priority" carrier. Additionally, as described, the carrier priority may be defined in a network specification or otherwise controlled by the wireless network or by one or more devices providing wireless network access to the UE (for example, based on previous usage , capacity, available resources, and so on). For example, PUSCH transmission over the "high priority" carrier may have a higher priority than PUSCH transmission over one or more other carriers.
    [0058] According to an aspect, the UE may comprise multiple power amplifiers and antennas associated with the power amplifiers. In this case, various power amplification and channel prioritization schemes can be used to effectively transmit the data over the wireless network.
    [0059] Figure 4 illustrates an illustrative system that facilitates carrier prioritization and power control in wireless networks. A wireless device 402 is provided, which can be a mobile device, UE, access terminal, or any power limited device that communicates over a wireless network. A network device 404 is also illustrated that can communicate with wireless device 402. Network device 404 can additionally be an access point, upstream network component, or any device that communicates with wireless device 402 .
    [0060] Wireless device 402 may comprise a carrier prioritization component 406 that may classify one or more carriers for transmitting high priority traffic, low priority traffic and/or varying priority levels of traffic, a component of power adjustment 408 that can modify the transmit power of one or more antennas to transmit data over one or more carriers based on their respective priority levels, and a transmit component 410 that can transmit data over the carriers using multiple antennas at the proper potency. As described, carriers can relate to logically defined channels, such as data or control channels - the type of data transmitted over the channels can be used in determining the priority for the related carriers. Network device 404 may optionally comprise a prioritization notification component that can develop or receive carrier prioritization and transmit the prioritization to wireless device 402.
    [0061] In one aspect, wireless device 402 can communicate with network device 404 directly or through one or more additional components. Wireless device 402 may transmit signals to network device 404 or other device, for example, over one or more frequency carriers. Channels can be logically defined through collections of carriers, such as physical uplink data channels (which can be shared between wireless devices), uplink control channels, and so on. Based on the channel and/or data for transmission over the channel, the carrier prioritization component 406 may classify the channel-related carriers and/or designate the carriers as high, low or other intermediate priorities.
    [0062] In one aspect of the present description, the carrier prioritization component 406 can maintain prioritization for a collection of carriers based on previous priorities, available resources, sensitivity of data transmitted over channels, and/or the like. Power adjustment component 408 may select one or more transmit powers for one or more signals through the collection of carriers based on prioritization, and transmit component 410 may transmit signals over carriers using one or more antennas at selected powers .
    [0063] In another aspect of the present description, the prioritization notification component 412 may provide carrier prioritization component 406 with a specified carrier prioritization per network, as described. It will be appreciated that the prioritization scheme may be specified as relating to at least two types of data to be transmitted via one or more antennas, for example.
    [0064] For certain aspects of the present description, the carrier prioritization component 406 and the power adjustment component 408 can prioritize the carriers and distribute power for PUCCH and PUSCH through multi-carrier in the case of power limited wireless device 402 of according to the following procedure.
    [0065] PUCCH can be accommodated primarily through carriers. This can be done according to a priority of each carrier, if carrier priorities are set. In one aspect, scaling factors can be defined to determine a fraction of power used for each carrier. Uniform power distribution across the carriers may represent the special case where the scaling coefficients are equal.
    [0066] If none of the explicit carrier priorities are set, PUCCH components can be prioritized for transmission in that particular order: multi-carrier ACK/NACK feedback, single-carrier ACK/NACK (where ACK/NACK MIMO has a higher priority than than ACK/NACK SIMO), ACK/NACK multiplexed with Schedule Request (SR) CQI/PMI/RI, Rating Indicator (RI), CQI/PMI (where broadband CQI/PMI has a higher priority than Subband CQI/PMI), and Sound Reference Signal (SRS).
    [0067] If explicit carrier priorities are set, ACK/NACK feedback of all carriers can be accommodated according to carrier priority, but before any other type of feedback can be accommodated, regardless of carrier priority. For example, ACK/NACK from a carrier with a lower priority may take precedence over a CQI feedback from another carrier with a higher priority than the ACK/NACK carrier. This may apply to ACK/NACK transmission only. For other channels, carrier priority may take precedence.
    [0068] PUSCH can be accommodated through carriers following the accommodation of PUCCH. In one aspect, uniform power scaling may be sufficient for PUSCH accommodation. Priority-based power scaling may be desirable if there are "high priority" carriers that carry delay-sensitive traffic (QoS sensitive scheduling across the carriers). In one aspect of the present description, high priority carriers can be assigned high priority and therefore QoS sensitive data can be placed on these carriers. In another aspect, carriers with QoS sensitive data can only represent regular carriers, which can become high priority carriers if QoS sensitive data is placed on them, in case of UE power limitation.
    [0069] If all carriers have the same priority, the power allocated for data transmission can be scaled evenly across the carriers. If there is multiplexed control information along with the PUSCH data, transmission of the control information along with the PUSCH data can be prioritized by transmitting pure PUSCH data. Additionally, PUSCH can be eliminated and PUCCH can be transmitted only if necessary due to a transmission power restriction. Additionally, RRC and MAC signaling (eg, power space report, measurement reports, etc.) transmitted on PUSCH may have priority over at least one of: regular data transmission on PUSCH over one or more other carriers, transmission of regular data in the PUSCH along with the uplink control information (UCI), or PUCCH transmission. Single and Multiple Power Amplifier Operation
    [0070] In case of a single PA implementation in the UE and transmission over one or more carriers, all the above mentioned rules for power control transmission and channel prioritization can be applied directly.
    [0071] When the power adjustment component 408 controls power for multiple PAs (e.g. related to multiple antennas), different types of data can be simultaneously transmitted over multicarrier. For example, ACK can be transmitted with SRS, CQI and/or the like using one antenna for ACK and one for other data types, using both antennas for both data types, and so on. Generally, in another example, control data can be transmitted through one antenna at one power with user plane data transmitted through another antenna at another power. Various transmission combinations are possible, and a subset of examples are given in the description.
    [0072] Depending on the UE operation regime, it may be desirable to preserve the SC property of the UL transmission in each of the PAs/antennas used. A subset of PAs can be used up to their maximum available transmit power, and the rest of the PAs can be turned off. The same information can be transmitted in all APs/antennas in order to achieve transmission diversity. Additionally, beam forming and cyclic delay diversity (CDD) can be applied. The PA transmit power can be filled with more than one channel according to a channel prioritization, as necessary and possible. However, this can break the SC property of UL transmission.
    [0073] Several interactions may be necessary to find a preferred transmission combination between the PHY channels and the available PAs/antennas. Certain aspects of the present description support the implementation of two PAs/antennas in the UE.
    [0074] In one aspect, ACK or ACK/SR can be transmitted along with SRS, or only SR can be transmitted along with SRS. If shortened format is allowed (ie, simultaneous AN and SRS indicator is determined TRUE by higher layers), then ACK or ACK/SR or SR, and SRS can be transmitted on both PAs/antennas with shortened format. Shortened format 1 can be used to transmit SR, and shortened format 1a/1b can be used for ACK. SRS can be transmitted on one or both antennas per configuration. This approach can preserve the SC property of UL transmission.
    [0075] On the other hand, if the shortened format is not allowed (that is, simultaneous AN and SRS is set to FALSE by the upper layers), then ACK or ACK/SR or SR can be transmitted with regular format in both PAs/ antennas. SRS can be transmitted on one or both APs/antennas if there is enough transmit power. Otherwise, SRS can be dropped, and regular format ACK can be transmitted. Regular format 1 can be used to transmit SR, and format 1a/1b can be used for ACK. SRS can be transmitted on one or both antennas per configuration. It should be noted that ACK transmission using regular format together with SRS may break the SC property of UL transmission.
    [0076] In one aspect, ACK or ACK/SR can be transmitted along with CQI. ACK or ACK/SR and CQI can be transmitted on separate resources on both APs/antennas. Regular format 1a/1b can be used to transmit ACK, and regular format 2 can be used for CQI. This can break the SC property of UL transmission.
    [0077] Alternatively, ACK or ACK/SR and CQI can be transmitted in different PA/antenna. Regular format 1a/1b can be used to transmit ACK on one PA/antenna and regular format 2 can be used to transmit CQI on the other PA/antenna. ACK can be further transmitted in the PA bearing CQI, if AN and simultaneous CQI are determined to be TRUE by higher layers. Regular format 2a/2b can be used for CQI/ACK. This can preserve the SC property of UL transmission.
    [0078] In one aspect, SR can be transmitted along with CQI. SR and CQI can be broadcast on separate resources on both PAs/antennas. Regular format 1 can be used for transmitting SR, and regular format 2 can be used for CQI. This can break the SC property of UL transmission. Alternatively, SR and CQI can be transmitted on separate antennas/PAs. Regular format 1 can be used for SR transmitted on one PA/antenna, and regular format 2 can be used for CQI transmitted on the other PA/antenna. This approach can preserve the SC property of UL transmission.
    [0079] In one aspect, SR/SRS can be transmitted along with CQI. If shortened format to SR is allowed, then SR/SRS and CQI can be transmitted on separate resources on both PAs/antennas. Shortened format 1 can be used for both SR and SRS, and shortened format 2 can be used for CQI. This can break the SC property of UL transmission.
    [0080] If shortened format to SR is not allowed, then SR/SRS and CQI can be transmitted in separate PA/antennas. Regular format 1 can be used to transmit SR on one PA/antenna, and regular format 2 can be used to transmit CQI on another PA/antenna. SRS can be transmitted on one or both antennas per configuration. This can break the SC property of UL transmission. In order to preserve SC property, SRS can be eliminated if there is not enough transmit power.
    [0081] In one aspect, SRS can be transmitted along with CQI. CQI can be transmitted on both PAs/antennas, and SRS can be transmitted on one or both PAs/antennas (by SRS configuration), if transmission power limitation allows. Regular format 2 can be used for CQI transmission together with SRS. This can break the SC property of UL transmission. One or both of the SRS can be dropped if there is not enough transmit power, while the SC property can be preserved.
    [0082] Alternatively, SRS can be broadcast on one PA/antenna and CQI can be broadcast on another PA/antenna. Format 2 can be used for CQI transmission on one PA/antenna and for SRS transmission on the other PA/antenna. A PA/antenna carrying SRS can be determined by the antenna broadcast program for SRS. If SRS is configured on both antennas and there is power available on the PA/antenna transmitting CQI, SRS can be transmitted simultaneously with CQI. Otherwise, SRS can be eliminated. It should be noted that transmitting CQI simultaneously with SRS may break the SC property of UL transmission.
    [0083] In one aspect, ACK or ACK/SR can be transmitted along with SRS and along with CQI. IF shortened format is allowed (ie AN and simultaneous SRS is determined to be TRUE by higher layers), then ACK or ACK/SR, SRS and CQI can be transmitted on separate resources in both PAs/antennas. Shortened format 1a/1b can be used for ACK transmission, and shortened format 2 or 2a/2b can be used for CQI transmission, if simultaneous AN and CQI is determined to be TRUE by higher layers. Using the 1a/1b shortened format and transmitting simultaneous SRS and CQI can break the SC property of UL transmission. If there is not enough transmit power, SRS and CQI can be power-dropped/scaled sequentially.
    [0084] In another aspect, if shortened format is allowed, ACK or ACK/SR and SRS can be transmitted on one PA/antenna and CQI can be transmitted on a separate PA/antenna. Shortened format 1a/1b can be used for transmitting ACK and SRS on one PA/antenna, and shortened format 2 can be used for transmitting CQI on the other PA/antenna. This can preserve the SC property of UL transmission.
    [0085] Additionally, ACK can be transmitted on antenna/PA carrying CQI, if AN and simultaneous CQI is determined as TRUE by higher layers. 2a/2b format can be used for CQI/ACK transmission. A PA/antenna carrying SRS can be determined by antenna broadcast scheduling for SRS. If SRS is configured on both antennas and if there is power available at the antenna/AP with CQI, then SRS can be transmitted simultaneously with CQI. Otherwise, SRS can be eliminated. It should be noted that simultaneous transmission of CQI and SRS may break the SC property of UL transmission.
    [0086] If shortened format is not allowed, (ie AN and simultaneous SRS is determined to be FALSE by higher layers), then ACK or ACK/SR, SRS and CQI can be transmitted on separate resources in both PAs/antennas . Regular format 1a/1b can be used for ACK transmission, and regular format 2 or 2a/2b can be used for CQI transmission, if AN and simultaneous CQI are determined to be TRUE by higher layers. Using regular format 1a/1b together with simultaneous transmission of SRS and CQI may break the SC property of UL transmission. If there is not enough transmit power, SRS and CQI can be sequentially eliminated/scaled in power.
    [0087] Alternatively, if shortened format is not allowed, ACK or ACK/SR can be transmitted on one PA/antenna and CQI can be transmitted on separate PA/antenna. Regular format 1a/1b can be used for ACK transmission on one PA/antenna, and regular format 2 or 2a/2b can be used for CQI transmission on the other PA/antenna (if the AN and simultaneous CQI indicator is set to TRUE by upper layers). If there is power available in one of the PAs, SRS can be transmitted simultaneously on that PA/antenna. Otherwise, SRS can be eliminated. Transmitting SRS simultaneously with CQI or regular format 1a/1b ACK may break the SC property of UL transmission. A PA/antenna carrying SRS can be determined by antenna broadcast scheduling for SRS.
    [0088] In one aspect, user data can be transmitted along with control information. ACK/CQI can be transmitted on PUCCH, and the rest of control and data can be transmitted on PUSCH on both PAs/antennas. Regular or shortened format 1a/1b can be used for ACK transmission, depending on the setting of AN and simultaneous SRS. SR can be transmitted with ACK in PUCCH, in addition to in addition to Storage Status Report (BSR) in PUSCH. If there is not enough available transmit power, PUSCH can be eliminated or power scaled. If both ACK and CQI are present, the above rules can be applied for PUCCH.
    [0089] SRS can be configured to transmit on both antennas. If AN and simultaneous SRS is determined to be FALSE by the upper layers and if there is still some transmit power available, SRS can be transmitted simultaneously with ACK. Otherwise, SRS can be eliminated. Regular format ACK transmission simultaneously with SRS may break the SC property of UL transmission. In one aspect, regular format 1a/1b can be used for ACK transmission. If simultaneous AN and SRS is determined to be TRUE by the upper layers, then a shortened ACK format and SRS can be transmitted simultaneously. The 1a/1b shortened format can be used for ACK.
