    The present invention relates to communication information about a subframe configuration for time division duplex (TDD) mode transmissions.
    A communication device can be understood as a device provided with appropriate control and communications capabilities to allow the use thereof to communicate with other parties. Communication can comprise, for example, voice communication, electronic mail (email), text messages, data, multimedia and so on. A communication device typically allows a user of the device to receive and transmit communication via a communication system and can therefore be used to access various service applications.
    A communication system is a facility that facilitates communication between two or more entities such as the communications device, network entities and other nodes. A communication system can be provided by one or more interconnected networks. One or more gateway nodes can be provided to interconnect various system networks. For example, a gateway node is typically provided between an access network and other communication networks, for example a core network and/or a data network.
    An appropriate access system allows the communication device to access a larger communication system. An access to the larger communication system can be provided by means of a fixed line or wireless communication interface, or a combination thereof. The communications system that provides wireless access typically allows at least some mobility for its users. Examples of these include wireless communication systems where access is provided through an array of cellular access networks. Other examples of wireless access technologies include wireless, local area networks (WLANs) and satellite-based communications system.
    A wireless access system typically operates according to a wireless standard and/or set of specifications that determine which various elements of the system are allowed and how they should be achieved. For example, the specification or standard may define whether the user, or more precisely user equipment, is provided with a circuit-switched carrier or a packet-switched carrier, or both. The communication protocols or parameters that must be used for the connection are also typically defined. For example, the manner in which communication is to be implemented between user equipment and network elements and their roles and responsibilities are typically defined by a predefined communication protocol. Such protocols and/or parameters further define the frequency spectrum to be used, through which part of the communication system, the transmission power to be used, etc. in cellular systems a network entity in the form of a base station provides a node for communicating with mobile devices in one or more cells or sectors. Note that in certain systems a base station is called "Node B (NB)" or "eNodeB (eNB)". Typically, the operation of one base station apparatus and another apparatus of an access system is necessary for the communication is controlled by a centralized control entity (which centralized control entity is typically interconnected with other entities, namely the centralized control communication network), or each base station (eg eNodeB) contains its own control entity Examples of cellular telephony access systems include, in order of their evolution, GSM (Global System for Mobile) EDGE (Enhanced Data for GSM evolution) radio access networks (GERAN), Universal Terrestrial Radio Access Networks (UTRAN) and evolved UTRAN (E-UTRAN).
    Referring to Figure 8, according to the Long Term Evolution (LTE) for E-UTRAN, downlink and uplink transmissions are organized into radio frames of a specified period, each frame consisting of consecutive subframes, and each subframe. - frame consists of a number of consecutive orthogonal frequency division multiplexing (OFDM) symbols.
    In TDD mode, a single bandwidth is shared between uplink and downlink transmissions, and different time resources are allocated to uplink and downlink.
    There are a number of different ways to share subframes within a frame between uplink and downlink transmissions, but they are each characterized by the use of at least one special subframe (SSF) that contains both portions. of downlink, i.e. DwPTS and uplink transmissions i.e. UpPTS separated by a portion of unused symbols in the middle of the subframe i.e. GP. According to one proposal, the lengths (in terms of OFDM symbols) of the uplink and downlink portions can take one of a limited number of combinations, the specific and selected combination for the network side for a cell is communicated to those served by devices cell communication in a TDD-Config information element.
    It has been proposed to increase the number of possible special auxiliary chassis configurations in some relatively advanced communication devices, with the aim of increasing transmission capacity, and the challenge of communicating special configuration information sub-frame has not been identified. such a system developed involving communication devices of different capacities. Achieving this goal is a goal.

    The following description refers to the example of a communication system including a radio access network designed to operate in accordance with Long Term Evolution (LTE) release 10/11 or beyond.
    Figure 1 illustrates an example of cellular E-UTRAN including a network of 2, 4, 6 base stations (eNBs).
    For simplicity, only three cells are shown in Figure 1, but a large cellular radio access network can have tens of thousands of cells.
    Figure 2 illustrates some components of an example of user equipment as shown in figure 1. User equipment (UE) 8 can be used for various tasks, such as making and receiving telephone calls, for receiving and sending data to and from a data network and to experience, for example, multimedia or other content.
    UE 8 may be any device capable of at least sending or receiving radio signals. Non-limiting examples include a mobile station (MS), a portable computer equipped with a wireless interface card or other wireless interface facilities, a personal data assistant (PDA) equipped with wireless communication capabilities, a relay node, or any combinations of these or the taste. UE 08 can communicate via a suitable radio interface arrangement of UE 8. The interface arrangement may be provided, for example, via a radio part and associated antenna arrangement. The antenna arrangement can be arranged internally or externally to the UE 8.
    The UE 8 may be provided with at least one data processing entity 3, and at least one entity data storage memory, or 7 for use in tasks to be performed. The data processor and 3 7 memory can be provided on an appropriate circuit board 9 and/or in chipsets.
    The user can control the operation of the UE 8 by means of a suitable user interface, such as a keyboard, voice commands, touch screen or pad, combinations thereof or the like. The display 5, may also be provided a speaker and a microphone.
    In addition, the EU May 8th include appropriate connectors (wired or wireless) for other devices and/or for connecting external accessories, eg hands-free equipment, thereto.
    Figure 3 illustrates some of the components of an example of an apparatus suitable for the access nodes 2, 4, 6 shown in Figure 1. The apparatus 2 may include a radio frequency antenna 301 configured to receive and transmit radio frequency signals, radio frequency interface circuitry 303 configured to connect radio frequency signals received and transmitted by antenna 301. The radio frequency interface circuit may also be known as a transceiver. Apparatus 2 may also comprise a processor 306 configured to process radio frequency signal data from interface circuit 303, controlling radio frequency interface circuit 303 to generate the appropriate RF signals. The access node may further comprise a memory 307 for storing data parameters and instructions for use by data processor 306.
    It should be understood that both the UE and 8 access nodes shown in figures 2 and 3, respectively, and described above may comprise other elements that are not directly involved with the embodiments described below.
    Figures 4 and 5 illustrate an example of operation on the network side and on the user equipment side in the system of Figure 1, the communication.
    With reference to Figures 8 and 9, the set of subframes that constitute a radio frame are divided into downlink and uplink transmissions according to one of the 7 configurations shown in Figure 9, and each uplink-downlink configuration can be seen at include at least one special substructure of the type mentioned above. Slots into which any subframe is divided (14 slots in normal cyclic prefix (PB) cases, or 5 12 slots in extended cyclic prefix (PB) case) can be used for transmission of OFDM symbols.
    The 14 slots (or 12 slots, in case of using an extended CP) of a special subframe (SSF) include: one or more downlink transmission slots at the beginning of the subframe (collectively referred to as the Downlink Pilot Time Slot , (DwPTS)); one or more unused slots 10 in the middle of the sub-frame (collectively referred to as the guard period (GP)), and one or more uplink transmission notches at the end of the sub-frame (collectively referred to as the Uplink Pilot Time Slot , (UpPTS)).
    Nine different combinations of DwPTS, GP and UpPTS are illustrated in Figure 10, where the length of the DwPTS and UpPTS are expressed in terms of the number of 15 OFDM symbols. Other examples of combinations of DwPTS, GP and UpPTS for a special subframe are illustrated in Figure 11.
    The access network decides to adopt an SSF configuration, which is not included in the set of SSF configurations shown in Figure 10 which is the preferred configuration for the cellular SSF associated with eNB 2. For example, the access network decides to adopt the (6 , 6, 20 2) SSF configuration shown at the top of Figure 11 as the preferred configuration for the cell associated with eNB 2. (6.6, 2) refers to the length of the DwPTS, GP and UpPTS, respectively, -in terms of number of OFDM symbols.
    The access network selects from the limited number of special subframe configurations illustrated in Figure 10 a default SSF configuration to pair with the preferred 25 SSF configuration. One or more of the configurations illustrated in SSF
    Figure 10 can be paired with one or more additional SSF configurations of the type illustrated in Figure 11, in other words, additional SSF configurations of the type illustrated in Figure 11 can include two or more, which are combined with the same default SSF configuration.
    In this embodiment, the access network selects from the limited number of special subframe configurations illustrated in Figure 10 a configuration that has an SSF DwPTS and UpPTS that are each no more than the DwPTS and UpPTS, respectively, of the preferred configuration (6,6.2). For example, the access network selects the (3, 9, 2) of the configuration identified by the special substructure parameter (SSP), value 5.
    The access network formulates a "TDD-Config" information element of the type illustrated in Figure 12, and depending on the value "5" for the SSP value, or any other SSP value identify a default SSF configuration than the network or station base has paired with the preferred SSF configuration. The TDD-Config information element also specifies one of the uplink-downlink configurations illustrated in Figure 9, via one of the seven subframe assignment (sa) values identified in Figure 9. of ENB the configuration of the TDD information element as part of a system 1 information block (Sib1) message of the type illustrated in Figure 13 on Downlink Shared Channel Physics (PDSCH) together with a Downlink Control Information (DCI ) message transmitted on the Physical Downlink Control Channel (PDCCH), indicating the allocation of resources for PDSCH transmission (STEP 402) This DCI message is scrambled with the Radio Network Temporary Identifier (RNTI) for the information system, ie, SI-RNTI. This TDD configuration information element is detectable by all 8 UEs (STEP 502). The UEs 8 all find the message with the DCI
    SI-RNTI as a result of a blind search of the PDCCH, and all obtain from the DCI message the configuration of the PDSCH carrying the corresponding Sib1.
    Table 1 below provides an explanation of the fields used in block 1 (Sib1) 15 system information message illustrated in Figure 13.


    Table 1
    The eNB 2 determines whether the UE 8 is one that is capable of operating in accordance with the preferred co-configuration (Step 404). If the result of this determination is positive, the access network also formulates an "RRC Connection reconfiguration" message addressed to that UE 8 and includes a "PhysicalConfigDedicated" information element of the type illustrated in Figure 14 and specifying the preferred substructure, for example the configuration (6, 6, 2) by means of a new predefined default SSF parameter value ( such as ssp 0 9 for the setting (6, 6, 2) recognizable for the UE 8 to which the message is addressed.
    Table 2 below provides a description of the fields of the dedicated configured physical information element illustrated in Figure 14.
    Table 2
    The eNB 2 sends the RRC Connection reconfiguration message to the UE 8 in the Physical Downlink Shared Channel (PDSCH) together with a message transmitted in the PDCCH ICD and scrambled with the RNTI assigned to the UE 8 in turn in the cell (i.e., C - RNT!) (Step 408). The UE finds this PCI message with its C-Rntl as the result of a blind PDCCH search, and obtains from the DCI message the configuration of the corresponding PDSCH carrying the RRC Connection reconfiguration message.
    In this way, the eNB 2 only sends an indication of the preferred SSF configuration to the UEs 8 that have the capability to operate in accordance with the preferred configuration of the SSF. If the result of the above-mentioned determination is negative for any UE, the eNB2 schedules broadcasts originating from and/or from any UE 8, according to the standard SSF configuration (Step 406).
    Those UEs 8 to which the eNB 2 does not send an indication of the preferred configuration SSF configure themselves for operation in accordance with that specified in the configuration of the Sibl message element detected in the PDSCH STEP (506) TDD-Config information.
    Those UES 8 that receive an RRC connection reconfiguration message including an indication of the preferred SSF configuration refrain to reconfigure themselves for operation in accordance with the preferred SSF configuration at least until after sending a Connection complete RRC reconfiguration message to the eNB 2 (STEP 508). Until eNB 2 receives the full RRC reconfiguration message from UE 8, eNB 2 continues to schedule transmissions to UE 8 according to standard SSF configuration (Step 414). After receiving the Connection reconfiguration complete RRC message from the UE 8, eNB 2 begins scheduling transmissions to that UE 8 according to the preferred configuration of the SSF (Step 412).
    For the period of uncertainty between the UE 8 sending the connection RRC reconfiguration complete message and the eNB 2 receiving this message, the UE 8 can continue to operate according to the default SSF configuration specified in the TDD-Config information element, while at the same time , OFDM symbol detection checking for the additional time resources allocated to downlink transmissions as part of the preferred SSF configuration (6, 6, 2).
    Figures 6 and 7 illustrate another example of operations on user-side network-side equipment and according to an alternative technique. As in the technique described above, the ENB two transmissions as an indication of the default configuration in SSF PDSCH as part of Sib1 (Step 602), which is detected by all UEs 8 (Step 702). The eNB 2 also includes an indication of the preferred configuration SSF (6, 6, 2) as part of a second information block message from the PDSCH channel transmission system together with a message transmitted over the ICD PDCCH and indicating the assignment of PDSCH transmission capabilities. The message is DCI encoded with the aforementioned SI-RNTI (STEP 604). An example of such a message is a Type 2 Block Information System (SIB2) message of the type illustrated in Figure 15. The indication of the preferred configuration is transmitted in the PDSCH, in such a way that it is not recognizable to the UEs 8 incapable of function in accordance with the preferred SSF configuration, and such UEs 8 continue to configure themselves for operation in accordance with the standard SSF configuration specified in the TDD-Config information element (STEP 706).
    Table 3 below provides an explanation of the type 2 system information message block fields illustrated in Figure 15.


    Table 3
    The U Es 8 that are able to detect the indication of the preferred configuration of the SSF PDSCH SIB2 and can operate in accordance with the preferred (6, 6, 2) configuration immediately reconfigure themselves accordingly (STEP 708), and the eNB 2 also immediately begins scheduling such transmissions for UEs according to the SSF (6, 6, 2) preferred configuration (Step 610). As mentioned above, the eNB 2 is able to distinguish between UEs 8 that can operate in accordance with the preferred SSF configuration and those that cannot, and for those UEs that do not have the ability to operate in accordance with the preferred SSF configuration , ENB the two timetables for the transmissions and/or from such UE 8 according to the standard SSF transmission configuration in PDSCH Sib1 (STEP 608).
    For the purpose of making measurements on eNBs associated with neighboring cells (ie, potential target cells), õ ÜE 8 makes such measurements based on the standard SSF setting (eg (3, 9, 2), in the example given above), ie it only takes measurements on the slots assigned to DwPTS according to the default SSF configuration. For the purpose of taking measurements on the eNB 2 associated with the current cell, a UE 8 capable of operating in accordance with the preferred configuration of the SSF (eg (6, 6,2) in the example given above) makes measurements of the slots allocated to the DwPTS according to the preferred SSF configuration, including the additional ranges that are not assigned to DwPTS in the default SSF configuration.
    The above description refers to the example of a preferred configuration of SSF with increasing time resources for DwPTS and the same time resources for UpPTS. However, the same type of technique also applies to Preferred SSF configurations with greater time resources for both DwPTS and UpPTS and Preferred SSF configurations with greater time resources for UpPTS and the same time resources for DwPTS. As mentioned above, the access network selects from the set of SSF configurations illustrated in Figure 10 an SSF configuration pattern having time resources for the DwPTS and UpPTS that are no more than the respective time resources in the preferred SSF configuration .
    The operations described above may require processing in the various data entities. Data processing can be provided through one or more data processors.
    Similarly several entities described in the above embodiments may be implemented within a single or a plurality of data processing entities and/or data processors. Product adapted computer program code
    They can suitably be used to implement the embodiments when loaded into a computer. The program code product to provide the operation may be stored and delivered by means of a carrier means, such as a carrier disk, card or tape. One possibility is to download the product program code via a data network. The implementation can be provided with appropriate software on a server.
    For example, the embodiments can be implemented as a set of chips, in other words, a series of integrated circuits that communicate with each other. The chipset may include microprocessors arranged to execute the code, application specific integrated circuits (ASICs), or programmable digital signal processors to perform the operations described above.
    Embodiments can be practiced on various components, such as integrated circuit modules. Integrated circuit design is largely a highly automated process. Complex and powerful software tools are available to convert a logical level design into a semiconductor circuit design ready to be recorded and formed on a semiconductor substrate.

Once the design of a semiconductor circuit has been completed, the resulting design, in a standardized electronic format (eg, opus, GDSil, or the like) can be transmitted to a semiconductor fabrication facility or "Fab" fabrication.
    In addition to the modifications explicitly mentioned above, it will be apparent to one skilled in the art that various other modifications of the techniques described can be made, and that the techniques described have application in other communication systems.
