Power optimization using scheduling request delay

摘要

Certain aspects of the disclosure relate generally to techniques for managing scheduling requests (SRs) for resources for uplink transmission. For example, certain aspects of the present disclosure relate to a method for wireless communication including determining a transmit opportunity for transmitting SR for uplink resources based, at least in part, on a discontinuous reception (DRX) time cycle. According to certain aspects, a user equipment (UE) may delay transmitting the SR based on the DRX time cycle to prevent repeated interruption of the DRX cycle that may reduce benefits of the power-saving DRX scheme.

主权项

1. A method for wireless communications by a user equipment (UE), comprising:
selecting a scheduling request (SR) delay based, at least in part, on a length of a discontinuous reception (DRX) time cycle and a channel condition; determining a transmission delay comprising a time interval to a first SR transmit opportunity for transmitting an SR for uplink resources that occurs after the SR delay; selecting an SR transmit opportunity based on a comparison of the transmission delay and a delay threshold; and transmitting the SR in the selected SR transmit opportunity.
