摘要： A method of wireless communication, by a user equipment (UE) includes receiving downlink semi-persistent scheduling (SPS) configurations. The method also includes receiving a physical downlink shared channel (PDSCH) transmission for each of the plurality of SPS configurations. Each PDSCH transmission has no associated physical downlink control channel (PDCCH). The method further includes determining whether successful decoding of each of the PDSCH transmissions occurred. The method further includes generating a hybrid automatic repeat request (HARQ) codebook for the PDSCH transmissions based on the determining. The method also includes transmitting the HARQ codebook in a physical uplink control channel (PUCCH) only when at least one ACK is present in the HARQ codebook.
