Title:
DYNAMIC HYBRID AUTOMATIC REPEAT REQUEST (HARQ) CODEBOOK FOR MULTI-USER PACKET (MUP) AND/OR UNICAST COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/226966
Kind Code:
A1
Abstract:
Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical downlink shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.
