Feedback corresponding to unified transmission configuration indicators in semi-persistent scheduling release downlink control information transmissions

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to:
• 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;
• 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;
• determine a location in the HARQ-ACK codebook for the HARQ-ACK feedback;
• receive an additional DCI transmission that indicates an additional unified TCI, wherein the additional DCI transmission comprises an additional SPS-release DCI transmission releasing the SPS PDSCH configuration;
• and
• either:
• identify the additional DCI transmission as an error based at least in part on determining that the additional DCI transmission is associated with the location in the HARQ-ACK codebook with which the DCI transmission is associated, wherein the additional DCI transmission comprises an additional SPS-release DCI transmission releasing an the SPS PDSCH configuration,
• determine whether a quantity of SPS PDSCH occasions in a set of SPS PDSCH occasions is greater than, or equal to, a quantity of unified TCIs in a set of unified TCIs that includes the unified TCI and the additional unified TCI, wherein the SPS PDSCH configuration corresponds to the set of SPS PDSCH occasions, wherein the location is determined in the HARQ-ACK codebook based at least in part on a plurality of locations associated with a plurality of SPS PDSCH occasions of the set of SPS PDSCH occasions, wherein each of a plurality of SPS configuration indexes of the plurality of SPS PDSCH occasions is lower than a configuration index of any SPS PDSCH occasion of the set of SPS PDSCH occasions that is not also in the plurality of SPS PDSCH occasions, or
• determine a location in the HARQ-ACK codebook for an additional HARQ-ACK feedback corresponding to the additional DCI transmission based at least in part on a dedicated bit, of one or more bits appended to the HARQ-ACK codebook, being associated with the at least one additional DCI transmission.
