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： 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.

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.
