Title:
MULTICAST TRANSMISSION FEEDBACK AND BUFFER PROCESSING
Document Type and Number:
WIPO Patent Application WO/2021/222725
Kind Code:
A3
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARQ) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.
