Abstract: One problem with current D2D communications is that there is no physical layer feedback (e.g., HARQ feedback) for unicast sidelink communications. That is, the transmitting UE does not know if the receiving UE receives and/or properly decodes the unicast transmission. Instead, current D2D communications require that a transmitting UE send a unicast sidelink communication multiple times to increase the chances that the unicast sidelink communication is received by the receiving UE. By blindly transmitting unicast sidelink communications multiple times, the spectral efficiency and radio resource utilization of the network is decreased. The present disclosure provides a solution to this problem by enabling HARQ feedback for unicast sidelink communications that improves the spectral efficiency and also enables better radio resource utilization for the network.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first link quality. The first link quality indicates a link quality of a first link between a first potential relay UE and the remote UE. The apparatus determines a second link quality. The second link quality indicates a link quality of a second link between the first potential relay UE and a first base station. The apparatus ranks the first potential relay UE relative to a second potential relay UE. The ranking of the first potential relay UE is based on a combination of the first link quality and the second link quality. The apparatus selects one of the first potential relay UE and the second potential relay UE for a relay connection based on the ranking of the first potential relay UE relative to the second potential relay UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity receives measurement reports that indicate a non-reciprocity condition between link directions (e.g., as part of a multi-round trip time (RTT) position estimation session). In an aspect, the position estimation entity transmits request(s) to retrieve non-reciprocity source information, which may be used in position estimation derivation (e.g., to correct for error due to the non-reciprocity). In an aspect, the request(s) may be transmitted to a target UE and/or a wireless node involved in the position estimation session (e.g., serving gNB or TRP, another UE, etc.).

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may identify a limited detection range, such as a Line of Sight (LoS) blockage or reduced coverage. The UE may request inter-vehicle assistance from a centralized control entity to overcome this limitation. The CE may transmit an indication of a set of target objects tracked by a sensor at the UE and a level of accuracy for tracking the set of target objects. In turn, the centralized control entity may request sensor information from one or more UEs with a complete LoS, a larger coverage area, or both. Based on the available sensor information, the centralized control entity may collect and transmit the sensor information back to the first UE in response to the request for assistance.
