Abstract
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.
Claims32
A method used in a wireless communications system that facilitates communicating a Buffer Status Report (BSR), comprising:
- receiving a configuration related to a Semi-Persistent Scheduling (SPS);
- detecting the Buffer Status Report (BSR) associated with a logical channel that is triggered;
- evaluating whether an SPS transmission occurs within a BSR Prohibit time interval associated with the triggered BSR;
- conveying the BSR through an uplink shared channel when the SPS transmission opportunity occurs based upon the evaluation;
- detecting a Scheduling Request (SR) transmission that is triggered;
- and
- performing a random access channel (RACH) procedure when at least one of the SPS opportunity or the SR opportunity occurs after the BSR prohibit timer expires.
A wireless communications apparatus, comprising at least one processor configured to:
- receive a configuration related to a Semi-Persistent Scheduling (SPS);
- detect a Buffer Status Report (BSR) associated with a logical channel that is triggered;
- evaluate whether an SPS transmission occurs within a BSR Prohibit time interval associated with the triggered BSR;
- convey the BSR through an uplink shared channel when the SPS transmission opportunity occurs based upon the evaluation;
- detect a Scheduling Request (SR) transmission that is triggered;
- and
- perform a random access channel (RACH) procedure when at least one of the SPS opportunity or the SR opportunity occurs after the BSR prohibit timer expires;
- and
- a memory coupled to the at least one processor.
