    Abstract: Systems, methods, and circuitries are provided for configuring HARQ feedback for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) communication. In one example, a method includes identifying a physical uplink control channel (PUCCH) resource in a first slot for communicating a hybrid automatic repeat request (HARQ) codebook. The method includes determining a set of SPS PDSCH receptions for which feedback is multiplexed in the HARQ codebook based on SPS PDSCH configurations for each component carrier and each slot, a UE capability for number of SPS PDSCH receptions per slot, and a prioritization protocol. The method includes selecting a codebook type based on whether a PDSCH is scheduled by way of a dynamic grant for any of the plurality of slots, constructing the HARQ codebook based on the set of SPS PDSCH receptions and the selected codebook type, and transmitting the HARQ codebook to a next generation node

    Abstract: A wireless device may establish communication with a network node and determine a relationship between transmission configuration indication (TCI) and bandwidth part (BWP). The wireless device may then receive an indication of one of TCI or BWP from the network node followed by determining the other of TCI or BWP based on the indication and using the relationship between the TCI and BWP. Finally, the wireless device may perform downlink communication using the indicated one of TCI or BWP and determined other TCI or BWP. The network node may be comprised in a non-terrestrial network and may specify via RRC signaling the relationship between TCI and BWP for the wireless device. The indication of the TCI or BWP may be provided by downlink control information (DCI), medium access control (MAC) control element (CE), an inactivity timer, or RRC reconfiguration commands.
