摘要： Certain aspects of the present disclosure relate to a technique for managing contention-based uplink data transmissions. According to certain aspects, a base station may allocate a common contention-based resource to a plurality of user equipment (UEs). The plurality of UEs may utilize the contention-based resource to transmit uplink data without prior scheduling, which may result in transmission collisions. Certain aspects of the present disclosure provide a mechanism for determining which UE sent an uplink transmissions based on one or more transmission parameter signaled to the UEs.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a difference between a previous power management maximum power reduction (P-MPR) and a current P-MPR is determined. The previous P-MPR is the P-MPR when an indication is communicated that a power backoff is applied due to the previous P-MPR. A power headroom report (PHR) is triggered when the difference is greater than a threshold and the current P-MPR is greater than a sum of a maximum power reduction (MPR) and an additional MPR (A-MPR). Moreover, an apparatus is provided in which whether and how a P-MPR has changed is indicated in a PHR, and the PHR is transmitted. An apparatus is also provided in which a request is received from an evolved Node B (eNodeB) to report a P-MPR, and a PHR is transmitted including information related to the P-MPR.

摘要： Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

摘要： Techniques for controlling data transmission in a wireless communication system based on hybrid automatic retransmission (HARQ) are described. In one design, a user equipment (UE) may determine the number of HARQ processes (Z) supported by the UE, e.g., based on the amount of resources available at the UE. The UE may send information indicative of the number of HARQ processes supported by the UE to a Node B. The UE may thereafter receive data from the Node B on up to Z HARQ processes. In one design, the UE may receive data for non-guaranteed bit rate (non-GBR) traffic on up to Z HARQ processes and may receive data for guaranteed bit rate (GBR) traffic on up to all HARQ processes available in the system. In another design, the UE may receive data for both GBR traffic and non-GBR traffic on up to Z HARQ processes.

摘要： Techniques for performing in-order data delivery during handover in a wireless communication system are described. A user equipment (UE) may perform handover from a source base station to a target base station. The target base station may start a timer after a data path from a gateway to the UE has been switched from the source base station to the target base station. The target base station may receive forwarded packets for the UE from the source base station and may receive new packets for the UE from the gateway. The target base station may send the forwarded packets received prior to expiration of the timer to the UE before any new packets. The target base station may send the forwarded packets to the UE without waiting for the timer to expire and may send the new packets to the UE after the timer expires.

摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. A donor or other upstream access point can be provided with a filter mask, bit stream, and filter mask identifier generated by a related relay node for packets having given static header data. Thus, the donor or other upstream access point can apply the filter mask to incoming packet headers, and where a resulting bit stream matches the received bit stream, can replace at least a portion of the packet headers with the filter mask identifier. The relay node can subsequently decompress the packet headers based on the filter mask identifier. Similar functionality can be used for compressing uplink communications.

The system can include components that quantify an absence of protocol data units, ascertain whether a number of absent protocol data units exceeds the size of a transmission side grant, insert a sequence number associated with a first absent protocol data unit into an acknowledgement sequence number field associated with a partial status report, incorporates the sequence number associated with the first absent protocol data unit in the partial status report, includes sequence numbers of subsequent absent protocol data units into the partial status report without exceeding the transmission side grant, and sends the partial status report to the base station.

摘要： An apparatus, method, processor(s), and computer program product avoids user data loss by network-controlled, user equipment assisted handover in a wireless data packet communication system. A wireless receiver receives radio link control (RLC) packet data units (PDUs) from user equipment (UE) being served by a source node. A wireless transmitter commands the UE to handover. A network communication interface transmits RLC Uplink (UL) context from the source node to the target node, and transmits RLC Downlink (DL) initialization message and buffered in-transit DL RLC PDUs from the source node to the target node.

摘要： Techniques for sending data during handover with Layer 2 tunneling are described. In one design, a user equipment (UE) sends first Layer 2 packets to a source base station prior to handover to a target base station. The UE sends at least one second Layer 2 packet to the target base station, which identifies the second Layer 2 packet(s) as being intended for the source base station and thus forwards the second Layer 2 packet(s) to the source base station via a Layer 2 tunnel. The UE sends third Layer 2 packets to the target base station after the handover. The target base station processes the third Layer 2 packets to obtain IP packets and sends the IP packets to a serving gateway after a trigger condition, which may be defined to achieve in-order delivery of IP packets from the source and target base stations to the serving gateway.

摘要： A wireless network avoids delays in receiving status reports by having transmitters make sure that any outstanding Hybrid Automatic Repeat-reQuest (HARQ) processes in progress are all finished before sending the polling request. Thus, the receiver can respond to any polling request of the transmitter immediately without delay. Since the transmitter already ensures all HARQ processes are done, the receiver's status report will accurately reflect the latest information. The transmitter may send a poll anytime regardless of the HARQ processes if the most up-to-date polling is determined to be not as important (e.g., when the transmitter is trying to advance its transmitter window, in which case the exact Status info is not critical). The receiver may then react immediate upon receiving the poll. Thereby, detecting the loss of any piece of data within a data burst is expedited.
摘要翻译：无线网络通过使发射机确保正在进行的任何未完成的混合自动重复请求（HARQ）进程都在发送轮询请求之前完成，从而避免接收状态报告的延迟。因此，接收机可以立即立即响应发射机的任何轮询请求。由于发射机已经确保所有HARQ过程完成，所以接收机的状态报告将准确反映最新信息。如果最新轮询被确定为不重要，则发射机可以随时发送轮询，而不管HARQ进程如何（例如，当发射机试图推进其发射机窗口时，在这种情况下确切的状态信息是不重要）。接收者可能会在接收到投票后立即作出反应。因此，加速了数据突发内的任何数据丢失的检测。
