Title:
HARQ PROCESSING METHOD, USER EQUIPMENT, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2022/073486
Kind Code:
A1
Abstract:
A user equipment (UE) executes a hybrid automatic repeat request (HARQ) processing method to reduce HARQ-ACK payload by selecting semi persistent scheduling (SPS) physical downlink shared channels (PDSCHs) on a plurality of periodic SPS PDSCH resources and reporting HARQ-ACKs for the selected SPS PDSCHs. Alternatively, the UE reduces HARQ-ACK payload by reducing HARQ-ACK bits for SPS PDSCH occasions or for SPS PDSCHs. Alternatively, the UE reduces HARQ-ACK payload by skipping HARQ-ACK feedback, such as a HARQ-ACK codebook, for the SPS PDSCHs. The UE determines an adjusted slot or sub-slot location for transmission of a HARQ-ACK bit for an SPS PDSCH at slot or sub-slot n when a symbol in an original slot or sub-slot location for transmission of the HARQ-ACK bit for an SPS PDSCH is invalid or has collision.
