Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a request for a first set of base stations to transmit on demand positioning reference signals (PRS) in a first band, measures the on demand PRS from the first set of base stations in the first band, measures periodic PRS from a second set of base stations operating in a second band, and sends, to a positioning entity, positioning measurements of at least the on demand PRS and the periodic PRS.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a PRS sequence is determined based in part on a sidelink zone where a transmitting UE is located. A receiving UE may perform a blind search based on PRS sequence(s) associated with its own sidelink zone and/or neighboring sidelink zones. In other aspects, measurement reports may be conveyed to a position estimation entity with positioning measurements being associated with respective PRS sequences, which can then be correlated to the respective transmitting UEs at the position estimation entity so as to facilitate position estimation of a target UE.

Abstract: A method of cross validating a positioning reference signal includes: measuring, at a first UE, a first PRS resource to determine a first PRS measurement; receiving, from a second UE via sidelink communication, a second PRS measurement of a second PRS resource; and determining whether at least one of the first PRS measurement or the second PRS measurement is unreliable based on a relationship of the first PRS measurement to the second PRS measurement.

Abstract: Techniques for detecting non-line-of-sight (NLOS) wireless signal paths are described. In some embodiments, a method thereof may include receiving positioning information from one or more networked devices, the positioning information comprising information indicative of measurements of one or more wireless signals transmitted between one or more wireless network nodes and one or more UEs, location data indicative of a location of each of the one or more UEs, or a combination thereof; determining a commonality associated with the received positioning information; and based on the determined commonality, determining that the NLOS wireless signal path is present between the given UE and the one or more wireless network nodes.

Abstract: Techniques are provided for utilizing a sidelink discovery interface to determine a location of a user equipment (UE). An example method for determining a location of a mobile device according to the disclosure includes receiving one or more reference signals transmitted via a first radio access technology, determining measurement values for the one or more reference signals, receiving a discovery signal from a station via a second radio access technology that is different from the first radio access technology, wherein the discovery signal includes and identification value associated with the station, and obtaining the location based at least in part on the measurement values and the discovery signal.

Abstract: Apparatus, methods, and computer-readable media for facilitating signaling of network coding information to facilitate feedback processing are disclosed herein. An example method for wireless communication at a transmitting device includes encoding data packets based on a first network coding and transmitting encoded data packets to a receiving device. The example method also includes receiving network coding information and determining a second network coding applied by the receiving device based on the network coding information. Additionally, the example method includes receiving feedback from the receiving device and decoding the encoded data packets based on the second network coding applied by the receiving device. Further, the example method includes updating the first network coding applied by the transmitting device based on the feedback and the decoding of the encoded data packets.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may transmit a sidelink request to reserve a subset of data resources to a second UE, and may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The second UE may transmit a positive sidelink response if it is available for a data transmission. A third UE may transmit a negative sidelink response if it objects to the data transmission. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.
