Abstract
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. A user equipment (UE) may use timers to maintain an ON duration in DRX. The UE may receive, via downlink control information (DCI), an indication of a feedback transmission opportunity (TxOP) for a HARQ process. The UE may activate a timer at the end of the TxOP regardless of whether the UE transmits feedback in the TxOP to ensure that the UE remains active. In some implementations, a base station may provide the UE with multiple opportunities to transmit a feedback message. The UE may reactivate a timer after each feedback TxOP for the same HARQ process or may activate the timer after the first feedback TxOP and may refrain from activating the timer after subsequent feedback TxOPs for the HARQ process.
