摘要： Systems and methodologies are described that facilitate utilizing timers in conjunction with transmitting buffer status reports (BSR). A prohibit timer can be utilized to determine when BSRs can be transmitted to an eNB. The prohibit timer can be initialized or restarted upon transmitting a BSR to an eNB. A BSR retransmit timer can be used to determine when to retransmit a BSR. The BSR retransmit timer can be initialized upon transmitting a BSR to an eNB and restarted each time an uplink resource allocation is received from the eNB. Once the timer expires, if an uplink transmission buffer contains data (e.g., size>0), the BSR can be retransmitted to the eNB. Control data feedback can additionally be used to determine when to retransmit the BSR. In addition, in either case, the timer duration values can be provided by the eNB.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.
摘要翻译：描述了有助于在无线通信环境中采用周期性闭环功率控制校正的系统和方法。可以通过下行链路发送周期性功率控制命令，以控制和/或校正接入终端采用的上行链路功率电平。可以基于从接入终端发送的上行链路周期性传输来生成每个周期性功率控制命令。周期功率控制命令可以通过物理下行链路控制信道（PDCCH）或带内信令进行通信。此外，接入终端可以被分组以提高周期性功率控制命令的下行链路传输的效率。在释放接入终端上行链路资源时，可以停止周期性功率控制命令。例如，这些资源可以在接入终端的不活动时段之后解除分配。此后，接入终端可以发起随机接入（例如，利用开环机制）来恢复周期性功率控制命令传输。

摘要： Systems and methodologies are described that facilitate operating an access terminal in an LTE based wireless communication environment utilizing extended microsleep. While in non-DRX mode, an access terminal can operate in on state for a first period of time and in extended microsleep state for a second period of time. Further, the first and second periods of time can form a repeating pattern where these periods of time alternate. Thus, the access terminal can turn on its receiver for the first period of time (e.g., decode downlink information while in on state) and turn off its receiver for the second period of time (e.g., inhibit decoding of downlink information while in extended microsleep state). Further, the first period of time in the repeating pattern can be one TTI (e.g., 1 ms) and the second period of time in the repeating pattern can be a plurality of TTIs (e.g., 5 ms).

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： Systems and methodologies are described that facilitate signaling and/or utilizing uplink delay budget related feedback in a wireless communication environment. A lowest delay budget associated with a most urgent Radio Link Control (RLC) service data unit (SDU) retained in a buffer of an access terminal can be determined. Further, a portion of a Medium Access Control (MAC) header (e.g., two reserved bits, . . . ) can be configured to carry a code related to a delay threshold corresponding to the lowest delay budget. Moreover, the MAC header can be transferred to a base station. The base station can detect the code carried by the portion of the MAC header, and a delay threshold can be determined as a function of the detected code (e.g., utilizing a radio bearer specific mapping). According to an example, the access terminal can be scheduled for uplink transmission as a function of the delay threshold.

摘要： Systems and methodologies are described that facilitate communicating a Buffer Status Report (BSR) from user equipment (UE) while reducing the employment of a RACH procedure. A BSR Prohibit time interval can be triggered by a receipt of uplink data to the UE. The BSR can be conveyed utilizing an uplink-shared channel (UL-SCH) if a Scheduling Request (SR) or a Semi-Persistent Scheduling (SPS) occurs within the duration of the BSR Prohibit time interval. The BSR can be communicated utilizing a RACH procedure if a SR or SPS occurs upon the expiration of the BSR Prohibit time interval.
