    Abstract: An apparatus and system of user equipment (UE) location determination using Transmission-Reception Points (TRPs) are described. Uplink angle of arrival (UL-AoA). UL relative time of arrival (UL-RTOA), and/or UL sounding reference signal reference signal received power (SRS-RSRP) measurements use an UL Antenna Reference Point (ARP) identifier (ID), which is associated with a UL ARP location (TRP panel) that is relative to the TRP geographical coordinates. The Location Management Function (LMF) requests additional path reporting for UE positioning for downlink Time Difference of Arrival (DL-TDOA), UL-TDOA, and multi-round trip time (RTT) reporting. The additional path information includes relative time difference and path quality indicator values and possibly a path RSRP value. The LMF indicates a maximum number of additional paths to be reported. The expected value and uncertainty range for each TRP is reported for downlink angle of departure (DL-AoD) measurements.

    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.
