Title:
CONTROL OF DRX TIMER FOR ONE-SHOT HARQ FEEDBACK
Document Type and Number:
WIPO Patent Application WO/2023/132736
Kind Code:
A1
Abstract:
A method performed by user equipment in a wireless communication system, provided in the present disclosure, may comprise the steps of: identifying that DRX has been configured; receiving a physical downlink control channel (PDCCH) at an active time of the DRX, the PDCCH including information for requesting one-shot HARQ feedback; on the basis of a request for the one-shot HARQ feedback, performing HARQ feedback corresponding to an identifier (ID) of a first HARQ process; and starting a DRX HARQ round trip time (RTT) timer associated with the first HARQ process.
