    Background
    The present invention relates to various wireless access technologies have been proposed or implemented to enable mobile stations to carry out communications with other mobile stations or with wired terminals coupled with wired networks. Examples of wireless access technology include GSM (Global System for Mobile Communications) and UMTS (Universal Mobile Telecommunications System) technologies defined by the Third Generation Partnership Project (3GPP); and CDMA 2000 (Code Division Multiple Access 2000) technologies, defined by 3GPP2. CDMA 2000 defines a type of packet-switched wireless access network, referred to as an HRPD (High Rate Packet Data) wireless access network.
    Another newer standard that provides packet-switched wireless access networks is the 3GPP Long Term Evolution (LTE) standard, which seeks to improve UMTS technology. The LTE standard is also referred to as the EUTRA (Evolved Universal Terrestrial Radio Access) standard. EUTRA technology is considered to be a fourth generation (4G) technology, to which wireless network operators are migrating to provide enhanced services. Another alternative 4G wireless technology is WiMAX (Worldwide Interoperability for Microwave Access), as defined by IEEE 802.16. There are also other wireless technologies. summary
    In general, according to some embodiments, a method or system for performing uplink join processing by multiple base stations includes sending, by a serving base station, a request for uplink resources of a second base station to receive uplink data from a mobile station. The serving base station receives the first uplink data from the mobile station, and the serving base station additionally receives (from the second base station) the second mobile station uplink data received by the second base station using the uplink resources specified by the request.
    Other alternative aspects will become apparent from the following description, from the drawings and from the claims. Brief Description of Drawings
    Some embodiments are described with respect to the following figures:
    Figure 1 is a block diagram of an example of an arrangement that includes multiple base stations in which some embodiments may be incorporated;
    Figure 2 is a block diagram of illustrative logic implemented in base stations in accordance with some embodiments; and
    Figures 3 and 4 are timing diagrams to illustrate the operation of a serving base station and a splice processing base station, according to some embodiments. Detailed Description
    When a mobile station is in a region of a cell where the power of wireless signaling between the cell's base station and a mobile station is relatively weak, wireless communication can become unreliable. Weak signaling can result in lost data. Alternatively, the baud rate used has to be lowered to improve the reliability of wireless communications - however, reducing the baud rate leads to slower communications between the mobile station and the base station.
    In some embodiments, to improve wireless communications with a mobile station, merge processing between uplink database stations from the mobile station may be performed. In response to scheduling of uplink transmission by a serving base station (where a "serving base station" is the base station currently serving a particular mobile station to allow the mobile station to communicate in the network without the use of wires), the mobile station transmits uplink data to the serving base station. One or more adjacent base stations may assist with receiving the uplink data from the mobile station, and share the results of such uplink data received with the serving base station. These one or more adjacent base stations that assist with receiving the uplink data from the mobile station are referred to as junction processing base stations. By sending the uplink data received from a junction processing base station to the serving base station, the probability of the serving base station being able to retrieve the actual uplink data sent by the mobile station is improved. At the serving base station, the uplink data received directly by the serving base station from the mobile station is combined with the mobile station uplink data sent from a junction processing base station(s). The combined uplink data based on the uplink data received by the serving base station and the junction processing base station(s) are used to derive actual uplink data sent by the mobile station.
    One issue in performing join processing between the uplink database stations is that there is communication latency between the cooperating base stations. Such latency can prevent efficient uplink data splicing processing from a mobile station.
    According to some embodiments, to allow uplink data join processing even in the presence of communication delays between base stations, an advance scheduler (provided at a base station) can be used, which plans and communicates strategic requests of join processing. The advance planner performs tasks that are distinct from the tasks performed by a "normal" base station planner, which is also referred to as a "tactical" planner (where the normal or tactical planner performs typical planning tasks on behalf of mobile stations ).
    An advance scheduler at a serving base station is able to submit a junction processing request to a junction processing base station (which is to cooperate with the serving base station to receive uplink data from a station. mobile), where the tie processing request can inform the tie processing base station about the uplink resources of the tie processing base station that the serving base station intends to use. The join processing request is sent to the tactical scheduler of the join processing base station. The tactical planner at the junction processing base station can choose whether or not to schedule assistance based on predefined rules. For example, the junction processing base station may choose not to schedule assistance when receiving uplink data from the mobile station based on a comparison of the SINR (interference signal-to-noise ratio) of the junction processing base station (a SINR of wireless communication with a particular mobile station) with the SINR of the serving base station. For example, if the junction processing base station's SINR is worse than the serving base station's SINR by some predefined threshold, then the junction processing base station would not provide assistance. This rule may also be known in advance by the serving base station - in other words, if the serving base station determines that the junction processing base station's SINR is worse than the serving base station's SINR by a predefined threshold, then, the serving base station knows that it should not expect assistance when receiving uplink data from the junction processing base station. By using predefined rules when performing uplink data join processing, the cooperating base stations can predict each other's actions without requiring the cooperating base stations to actually exchange signaling to make the determination of whether the cooperating base stations can jointly processing the mobile station's uplink data, which can be associated with significant communication delays between nodes.
    Instead of using the SINR in relation to a predefined threshold, other indicators of relative strengths of noise and signaling can be used.
    In addition, a deterministic rule can also be specified when requests for resources collide. For example, if the serving base station requests uplink resources from the junction processing base station that would cause collision with other requests already made from the junction processing base station, then the deterministic rule can specify how such a collision would be resolved.
    Although reference is made to cooperation between a serving base station and a junction processing base station, it is noted that the serving base station may cooperate with multiple junction processing base stations to receive uplink data from a mobile station. . Note that the base station can refer to any wired system, for example, interconnected wireless LANs.
    By employing uplink data join processing according to some embodiments, wireless communication with a mobile station in a region with weak signaling is improved. Examples of such a weak signaling region may include the edge of a cell, or, alternatively, a region in which there are significant obstructions to wireless signaling. Furthermore, by employing techniques according to some embodiments, improved transmission rates (for uplink data) can be achieved so that an increased number of regions of a coverage area can support a high transmission rate. Furthermore, the average capacity of the cell can be increased using techniques according to some embodiments.
    Figure 1 is a schematic diagram of an illustrative system having a serving base station 102 and one or multiple junction processing base stations 104. In the following discussion, reference is made to the cooperation between the serving base station 102 (serving a mobile station 106) and a junction processing base station 104. It is noted that techniques discussed are applicable to a situation in which the serving base station 102 cooperates with multiple junction processing base stations 104.
    Base stations 102 and 104 are used to communicate wireless signaling with various mobile stations in the respective coverage regions of the corresponding base stations, where these coverage regions may also be referred to as cells. A "cell" can refer to a cell as a whole, a sector of the cell, or any segment of a cell.
    The service base station 102 includes a physical layer 108 and a media access control (MAC) layer 110. The physical layer 108 provides the lowest level of interface with the physical transmission media, which in this case is the unused link. of wires between the serving base station 102 and the mobile station 106. The MAC layer 110 provides an interface between the physical layer 108 and the higher protocol layer (which is part of higher protocol layers 112 shown in Fig. 1). .
    As further shown in Figure 1, each of the physical layer 108 and/or MAC layer 110 may include a respective combiner 114 or 16 (note that only one of combiners 14 and 116 may be provided in some examples, while in other examples both combiners 114 and 16 may be present). Combiner 114 or 116 is used to combine uplink data from the mobile station 106 received by the receiving base station 102 and the junction processing base station 104. Effectively, the combiner 114 or 116 combines uplink data received directly from from the mobile station 1096 by the serving base station 102, with uplink data from the mobile station 106 received by the junction processing base station 104 and sent to the serving base station 102 via a link 118 between the serving base station. 102 and the junction processing base station 104 (such as using an interface 17 at the serving base station 102 and a similar interface at the junction processing base station 104). The combined uplink data can be used to derive the actual uplink data sent by mobile station 106.
    Note that each junction processing base station (stations) 104 may include the same components as presented in the service base station 102. Although the base station 102 is the serving base station for the mobile station 106, it is observed that one of the stations base 104 may be the serving base station for another mobile station, and base station 102 may be a splice processing base station for such another mobile station.
    According to some embodiments, the service base station 102 includes an advance planner 120 and a tactical planner 122. The technical planner 122 is the planner who actually plans the resources for communication with the mobile station 106, where the planned resources include resources uplink and forward link capabilities.
    Advance planner 120 is provided to enable more efficient splice processing of uplink data from the mobile station 106. Advance planner 120 is able to issue a splice processing request to the splice processing base station 104, to request uplink resources from the base junction processing station 104 that the service base station 102 wishes to use to receive uplink data from the mobile station 106 for the purposes of uplink junction processing.
    By performing uplink data combining (from mobile station 106) at physical layer 108 or MAC layer 10, improved efficiency can be provided for upper layers of the serving base station, since upper layers would not have to be involved in the execution of the actual uplink data combination.
    Furthermore, the mobile station 106 would not have to be configured to allow uplink splice processing, which reduces implementation costs.
    Service base station 102 also includes a processor (or multiple processors) 124 which is connected with storage medium 126 (e.g., volatile memory device such as static or dynamic random access memory and/or storage device such as disk-based storage device or flash memory). Advance planner 120 and tactical planner 122 can be implemented with machine-readable instructions executable on processor(s) 124.
    Under some implementations, base stations 102 and 104 may conform to the Long Term Evolution (LTE) standard as defined by the Third Generation Partnership Project (3GPP). The LTE standard is also referred to as the EUTRA (Evolved Universal Terrestrial Radio Access) standard.
    Although reference is made to the EUTRA standard, it is noted that alternative embodiments may employ other wireless protocols. Thus, the techniques as discussed in this document are also applied for uplink junction processing by base stations according to other wireless protocols, including any one or more of the following: WiMAX (Worldwide Interoperability for Micro Access -wave), as defined by IEEE 802.16; CDMA (Code Division Multiple Access), as defined by 3GPP2; HRPD (High Rate Packet Data), as defined by 3GPP2; UMTS (Universal Mobile Telecommunications System), as defined by the 3GPP; EDGE (Enhanced Transmission Rates for GSM Evolution), as defined by 3GPP; GSM (Global System for Mobile), as defined by 3GPP; Wireless Local Area Network (WLAN), as defined by IEEE 802.11; and so on.
    In the following discussion, reference is made to the EUTRA standard - it is noted that in other implementations, other standards may be employed.
    According to the EUTRA standard, base station 102 or 104 is implemented as an enhanced node B (Enode B). A base station can perform one or more of the following tasks: radio resource management, mobile station mobility management, traffic routing, and so on. Generally, the term "base station" can refer to a cellular network base station or access point used in any type of wireless network, or any type of wireless transmitter/receiver to communicate with. the base station. The term "base station" can also encompass an associated controller, such as a base station controller or radio network controller. It is contemplated that the term "base station" also refers to a femto base station or access point. A "mobile station" can refer to a telephone set, a laptop computer, a personal digital assistant (PDA), or an embedded device such as a radioprotection monitor, attack alarm, and so on.
    As further shown in Fig. 1, base stations 102 and 104 can be connected with a service internetwork device 130 which is used to route bearer data packets. The service network interconnect device 130 also acts as a mobility anchor for the user plane during cell-to-cell transfers between different base stations. The service internetwork device 130 is also connected with a packet data network internetwork device (PDN) 132 which provides connectivity between a mobile station and a packet data network 134 (e.g. the Internet, a network that provides various services, etc.).
    Reference to the EUTRA standard is intended to refer to the current EUTRA standard as well as any standard that evolves over time from the EUTRA standard. It is expected that a future standard that evolves from the EUTRA standard may be referred to by a different name. It is contemplated that reference to "EUTRA" is intended to also cover such subsequently evolved patterns.
    Figure 2 illustrates various components of base station i and base station j which may correspond to base station 102 and 104, for example. One of base station i and base station j can be the serving base station, while the other base station is the junction processing base station. Input information 200 and 202 is provided for each of the respective advance planner i and advance planner j (contained in base station i and base station j, respectively). Input information 200 or 202 includes an audible reference signal (SRS) (transmitted by a mobile station so that the base station can use the SRS to estimate the quality of the uplink channel and other information); reports (containing various data of interest to advance planner i or j); buffer occupation (indicating the occupation of a buffer associated with a mobile station); and QoS information (quality of service information to indicate the quality of service to be provided for a particular transmission). It is noted that similar information (204 and 206) can also be provided for tactical planner i and tactical planner j, respectively.
    As further depicted in Figure 2, the early planner j at base station j can send a join processing request (208) to the tactical planner i at base station i. This would be performed in the situation where base station j is the serving base station, and base station i is the junction processing base station. The join processing request is based on advance planning performed by the advance planner before the actual planning performed by a tactical planner at the service base station.
    Similarly, advance planner i at base station i may send a join processing request (210) to tactical planner j at base station j, in the situation where base station i is the serving base station and the base station j is the junction processing base station.
    A tie processing request may specify the assignment of uplink resources of a tie processing base station (on behalf of the serving base station) for use to receive uplink data from a particular mobile station by the base station. of join processing. Other content contained in the join processing request may include, as examples, the mobile station identification, a temporary radio network identifier (RNTI), a modulation and coding scheme (MCS) (to specify the modulation and coding of the be used for improved signal quality), and/or other information.
    It is noted that the serving base station may also send a tie measurement request (not shown in Figure 2) to the tie processing base station, for the purposes of measuring signaling for the particular uplink resources. This allows the serving base station (and the junction processing base station) to know the relative SINRs so that a determination can be made, based on the SINRs, as to whether the junction processing base station should plan assistance for receiving uplink data from the mobile station.
    As further depicted in Fig. 2 , if base station j is the junction processing base station, the MAC layer of the user plane 110 and the physical layer 108 of the base station j can send the junction processing uplink data (214 ) to the serving base station i to perform the uplink data combining (215). Alternatively, if base station i is the junction processing base station, then the MAC layer of the user plane 110 and the physical layer 108 of the base station i can send the junction processing uplink data (216) to the station. j service base perform the combination of the uplink data (217).
    Fig. 3 is a time-relation diagram for uplink join processing according to some examples. The time diagram in figure 3 presents a sequence of time blocks, where each block has four TTIs (transmission time intervals), and each TTI represents a period of time with a predefined duration.
    In the timing diagram of Figure 3, "ADV" represents tasks performed by the advance scheduler (120 in Figure 1) of the serving base station, "PRP" represents tasks performed by a base station or mobile station to enable data communication uplink from the mobile station to a base station, and "DEC" represents the decoding tasks.
    In some implementations, it is assumed that hybrid ARQ (Automatic Repeat Request) is used, where error detection information bits and early error correction bits are added for the data to be transmitted through the error. HARQ information, including error detection bits and early error correction bits, allows the receiver to determine whether data received by the receiver contains an error. Early error correction bits allow correction of some data errors. If a data error cannot be corrected, then HARQ provides a mechanism for retransmitting data from the transmitter.
    In other implementations, error detection and correction mechanisms may be employed for wireless communications between a mobile station and a base station.
    As depicted in Figure 3, when uplink join processing is to be performed, the advance scheduler 120 at the service base station (after performing the ADV tasks) sends a join processing request (300) to the tactical scheduler 122 on the junction processing base station, which performs tasks represented as "JP PREP". As noted above, the tie processing request (300) may specify resource blocks from the tie processing base station that may be requested from the tie processing base station to receive uplink data from the mobile station for purposes of perform uplink join processing. Note that at this stage, the join processing request merely indicates that the service base station intends to schedule uplink data transmission in relation to these join processing base station resource blocks - which may not be based on various conditions.
    At a later point in time, the tactical planner at the serving base station performs PRP tasks 304 to send an uplink grant message (306) to the mobile station. Grant details are also sent (308) to the junction processing base station tactical planner, which indicates to the junction processing base station that the service base station actually planned the resource blocks specified by the processing request. of junction (300).
    In the example of Figure 3, the uplink grant (306) is sent with RV (redundancy version) set to zero. RV is a HARQ parameter that is used to specify which relay version to use. RV is used to indicate whether a previously transmitted block is to be forwarded by the mobile station, or the mobile station can perform the transmission of the next uplink data. In the example, RV equal to zero indicates that the mobile station can send the next uplink data.
    In response to the uplink grant (306), the mobile station performs various tasks 308, and sends (310) data in uplink on an uplink shared physical channel (PUSCH) to the serving base station and the base station. of join processing. Note that the uplink grant (306) specified that the mobile station is to use radio resources from both the serving base station and the junction processing base station, so that the uplink data sent by the mobile station (in 310) can be received by both the serving base station and the splice processing base station for uplink splice processing.
    When receiving the uplink data in the PUSCH, both the serving base station and the junction processing base station perform respective tasks (JP DEC, ADV, DEC, PREP) based on the received uplink data. In the example of Fig. 3, it is assumed that the base junction processing station is unable to successfully decode the uplink data received in the PUSCH - as a result, the base junction processing station sends a failure indication (312) to the service base station. Note that it may not be clear whether reception of the uplink data is successful or not at the time the HARQ feedback is to be provided by the serving base station to the mobile station. As a result, according to some embodiments, an acknowledgment (ACK) (314) is provided without an uplink grant. Instead, the ACK is provided with a suspend indication, which is sent to the mobile station. In response to the ACK with the suspend indication (314), the mobile station does not perform the uplink data transmission. Effectively, the ACK with the suspend indication effectively delays the provision of the HARQ feedback from the serving base station to the mobile station until the serving base station is able to determine whether or not the splice processing base station is able to cooperating with the serving base station to process the uplink splice data so that the serving base station can successfully decode the uplink data.
    In the example of Figure 3, it is assumed that in view of the failure indication (312) from the junction processing base station, and also in view of the fact that the serving base station is unable to successfully decode the data from uplink data received at 310, that the serving base station will request transmission of the same uplink data sent at 310. The serving base station sends (at 316) grant details with respect to the retransmission request to the serving base station. junction processing, and the serving base station in addition sends (at 318) an uplink grant to the mobile station with RV set equal to 2. This is a request for a retransmission of the same uplink data previously transmitted by the station. mobile.
    Fig. 4 is a timing diagram that is similar to the timing diagram of Fig. 3, except that the junction processing base station is able to successfully decode the uplink data sent in 310. The tasks of Fig. 3 are given the same reference numbers in Fig. 4. As indicated in Fig. 4, decoding (402) performed by the splice processing base station in response to the uplink data in the PUSCH received at 310 results in successful decoding. , which causes the junction processing base station to send the uplink data (at 404) to the serving base station. At the serving base station, such uplink data sent by the base junction processing station (404) can be combined with the uplink data directly received (310) by the serving base station from the mobile station, which results in a determination at the serving base station that the uplink data sent at 310 has been successfully received. As a result, the serving base station is able to schedule the transmission of the next uplink data from the mobile station, and the service base sends grant details (406) with respect to such scheduling of the next uplink data from the mobile station to the junction processing base station. The serving base station also sends an uplink grant (408) with RV equal to zero to indicate to the mobile station that the mobile station is to send the next uplink data.
    In Figure 4, it is observed that even though the data was successfully decoded by the junction processing base station, and that ultimately the serving base station was able to successfully decode the uplink data received at 310, at the point where HARQ feedback is needed, the serving base station is not yet able to send an uplink grant for the next uplink data from the mobile station. As a result, even in the example of figure 4, the serving base station sends an acknowledgment (ACK) with the suspension indication (314).
    In the examples of Figures 3 and 4, it is assumed that the splice processing base station is able to provide assistance for the uplink data splice processing. In other examples, the tactical planner at the junction processing base station can choose whether or not to schedule assistance based on predefined rules. For example, the junction processing base station may choose not to schedule assistance when receiving uplink data from the mobile station based on a comparison of the junction processing base station's SINR with the serving base station's SINR. For example, if the SINRj of the junction processing base station j is worse than the SINRj of the service base station I by some predefined threshold T (SINRj < SINRj - T), then the junction processing base station did not offer assistance. This rule can also be known in advance to the serving base station - in other words, if the serving base station determines that the junction processing base station's SINRj is worse than the serving base station's SINRj by the predefined threshold, then the serving base station knows that it does not expect assistance in receiving the uplink data from the junction processing base station.
    By using predefined rule(s) when performing uplink data join processing, cooperating base stations can predict each other's actions without requiring that the cooperating base stations actually exchange signaling to make the determination of whether the cooperating base stations can together processing uplink data from the mobile station, which can be associated with significant communication delays between nodes.
    If the junction processing base station chooses not to schedule assistance in response to the junction processing request, the junction processing base station may report this decision to the serving base station so that the serving base station knows that does not expect help from the junction processing base station. In other examples, the serving base station may already know that no help is expected from the junction processing base station, even without any feedback from the junction processing base station, from both the serving base station and the Junction processing systems employ the same rule(s) when determining whether or not the junction processing base station should provide assistance for uplink data processing.
    Using techniques or mechanisms according to some embodiments, bidirectional negotiation to perform uplink data join processing by multiple base stations can be avoided to reduce latency. Instead, predefined rules are used to govern behavior when performing uplink data join processing.
    Machine-readable instructions (such as instructions from the advance planner 120 and the tactical planner 122 of Figure 1) are loaded for execution on one or processors (such as 124 in Figure 1). A processor may include a microprocessor, microcontroller, processor module or subsystem, programmable integrated circuit, programmable gate array, or other control or computing device.
