    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: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to decode radio resource control (RRC) signaling from an authorized V2X network entity. The RRC signaling including configuration information to activate a sidelink transmit (TX) bandwidth part (BWP) of a plurality of sidelink TX BWPs within a sidelink carrier. Data is encoded for transmission to a second UE using a first sidelink signal. The processing circuitry is to cause transmission of the encoded data via the first sidelink signal. A bandwidth of the first sidelink signal during the transmission is within the activated sidelink TX BWP.
