Abstract: In an aspect, an initiator transmits a positioning reference signal. The initiator receives a plurality of responder positioning reference signals sent from individual responders of a plurality of responders. The initiator transmits a measurement message comprising a first set of measurements that are determined based on the positioning reference signal and the plurality of responder positioning reference signals. The initiator receives responder measurement messages sent from the individual responders of the plurality of responders. The initiator receives updated map information from an anchor and updates pre-existing map information based on the updated map information.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a request for a first user equipment (UE) to provide sensing capability information associated with UEs other than the first UE (e.g., an indication of one or more sensors associated with the corresponding UE, an orientation of the corresponding UE, a field of view associated with the corresponding UE). Additionally, the first UE may receive, from each of a set of second UEs, indications of the sensing capability information associated with the corresponding second UEs. Based on the sensing capability information indicated for each of the set of second UEs, the first UE select a subset of second UEs and transmit an indication of the sensing capability information associated with the subset of second UEs to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive a first set of ranging measurements based at least in part on a first one or more positioning reference signals communicated over a sidelink between a pedestrian user equipment (P-UE) and a vehicle UE (V-UE). The network node may receive a second set of ranging measurements based at least in part on a second one or more positioning reference signals communicated over an access link between the P-UE and one or more base stations. The network node may transmit, to the P-UE, an estimated position of the P-UE. For example, in some aspects, the estimated position of the P-UE may be based at least in part on the first set of ranging measurements and the second set of ranging measurements. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for grouping devices to reduce latency in round trip time based millimeter wave positioning. A method that may be performed by a wireless device includes obtaining a status, of the wireless device, within a group including the wireless device, wherein the group comprises a group owner (GO) of the group and one or more members of the group; and participating in a positioning procedure that estimates a position of at least one of the GO or the one or more members according to the status of the wireless device.

Abstract: Disclosed are some examples of techniques for ranging and positioning of distributed devices to avoid local and/or periodic interference. For example, an initiator user equipment (UE) can broadcast a positioning reference signal (PRS) message of a current positioning session to responder UEs. One or more characteristics of PRS transmission associated with a first responder UE in the current positioning session can be determined. Based on the characteristic(s), interference with the first responder UE can be identified, which can cause the initiator UE to change the broadcast order of the responder UEs for a next positioning session.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a method of wireless communication includes determining, based on environment information about an environment in which a user equipment (UE) that is receiving positioning reference signals (PRSs) using a first bandwidth (BW) is operating, a second BW to be used by the UE for receiving PRSs, and transmitting PRSs using the second BW to be used by the UE for receiving PRSs.

Abstract: In one example, a method being performed by a first station and comprises: transmitting a first message including an indication of whether a clock reconfiguration event occurs at the first station; transmitting a first positioning reference signal (PRS); receiving from a second station a second PRS; and transmitting to the second station a second message including a first time when the first PRS is transmitted by the first station and a second time when the second PRS is received by the first station, to enable the second station to determine a roundtrip time (RTT) between the first station and the second station based on the first time, the second time, a third time when the second station receives the first PRS, a fourth time when the second station transmits the second PRS, and the indication.

Abstract: A vehicle-enabled user equipment (VUE) and related techniques are disclosed. In one aspect, the VUE issues a periodic broadcast, or signals a response to a requesting source, identifying its location management capability (LMC). The UE forms a link with a recipient VUE of the broadcast to perform joint localization of the pedestrian UE (PUE). Joint localization by VUE and another VUE may be performed by VUEs and PUEs in the region exchanging ranging signals and ego measurements. The VUE determines a location jointly of the PUE. The location can be determined upon a request, periodically, or in response to a triggered event.
