摘要
The downlink data receptions include a set of one or more PDSCH receptions (PDSCH1, PDSCH2) belonging to a same group GO, scheduled by respective associated DCI elements (DCI1, DCI2) that indicate a same first slot (PUCCH1 slot) for a corresponding acknowledgement transmission, and a 'SPS' PDSCH reception (SPS-PDSCH1), for which an acknowledgment transmission is scheduled on the next of a plurality of fixed periodic slots. The UE determines that the first slot for acknowledgment transmission is the same as the next fixed periodic slot for acknowledgment transmission, generates a joint acknowledgment codebook concatenating a group codebook for group GO including an AN element for each dynamically scheduled PDSCH receptions of the group GO and a SPS codebook including an AN element for the 'SPS' PDSCH reception, and attempts to transmit the generated joint acknowledgment codebook on said first slot for acknowledgment transmission.
