Document Type and Number:
WIPO Patent Application WO/2022/193167
Kind Code:
A1
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) transmission that indicates a unified transmission configuration indicator (TCI), wherein the DCI transmission comprises a semi-persistent scheduling (SPS) -release DCI transmission releasing an SPS physical downlink shared channel (PDSCH) configuration. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK codebook, wherein the HARQ-ACK feedback comprises an acknowledgment (ACK) to indicate successful reception of the unified TCI in the DCI transmission or a negative acknowledgement (NACK) to indicate a failed reception of the unified TCI in the DCI transmission. Numerous other aspects are described.
