    Abstract: An apparatus and system for inter-UE coordination feedback for sidelink communications are described. In particular, inter-UE coordination feedback signaling for reliable sidelink communication including transmitter-based resource allocation and signaling of conflicts, prioritization of the inter-UE coordination feedback, and timing of the inter-UE coordination feedback are described. Sidelink hybrid acknowledgment request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) or NACK only signaling is prioritized over a half-duplex (HD) or co-channel collision (CC) feedback indication, and uplink transmissions are prioritized over sidelink transmissions. In response to detection of a conflict, the inter-UE coordination feedback is transmitted relative to the slot where the HD or CC event occurs or relative to the slot where reservation of the resources for the sidelink transmissions.

    Abstract: Systems and methods for transmission of PDSCH and HARQ-ACK feedback in 5G networks are described. The TDRA of PDSCH repetitions are indicated in a DCI by a SLIV sequence configuration that contains multiple SLIV sequences. Each SLIV sequence for a slot is associated with an independent repetition factor and may also be associated with a partition factor to indicate a partition within the slot. One or more TRPs may be used to transmit each PDSCH repetition. The TCI states are mapped to the PDSCH repetitions in a round-robin fashion using an offset in terms of number of PDSCH repetitions from where TCI state switching starts and a number of consecutive PDSCH repetitions per TCI state. The HARQ-ACK bits in response to the PDSCH from the TRPs are concatenated in order of increasing control resource set higher layer signaling index.
