Title:
METHOD FOR TRANSMITTING HARQ-ACK CODEBOOK, USER EQUIPMENT, DEVICE AND STORAGE MEDIUM, AND METHOD AND BASE STATION FOR RECEIVING HARQ-ACK CODEBOOK
Document Type and Number:
WIPO Patent Application WO/2021/100982
Kind Code:
A1
Abstract:
A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.
