Title:
APPARATUS AND METHOD FOR HARQ-ACK FEEDBACK FOR MULTICAST SERVICE
Document Type and Number:
WIPO Patent Application WO/2023/205991
Kind Code:
A1
Abstract:
The disclosure relates to apparatus and method for supporting Hybrid Automatic Repeat request (HARQ) -Acknowledgement (ACK) feedback for multicast service. In some aspects, a user equipment (UE) device may comprise at least one antenna; at least one radio, coupled to the at least one antenna and configured to perform wireless communication using at least one radio access technology; and one or more processors coupled to the at least one radio, wherein the one or more processors are configured to cause the UE device to: receive, from a base station, a Radio Resource Control (RRC) signaling which indicates that a semi-static codebook is configured for a Hybrid Automatic Repeat Request (HARQ) -Acknowledgement (ACK) feedback for both multicast and unicast and that a HARQ-ACK feedback for multicast is disabled; and generate a HARQ-ACK feedback report which excludes a HARQ-ACK bit for the multicast by using a time domain resource assignment (TDRA) for the unicast to configure the semi-static codebook.
