Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select, based at least in part on a sensor selection criteria, a first subset of sensors from a set of available sensors of the UE, each sensor in the set of available sensors associated with a sensor type. The UE may perform, using the first subset of sensors, sensing operations to obtain a first sensing data, the first sensing data comprising sensing data measured by the UE during the sensing operations. The UE may transmit a first sensing report indicating the first sensing data. The UE may receive, based at least in part on the first sensing report, a second sensing report indicating a second sensing data, the second sensing data comprising a unified sensing report based on the first sensing report from the UE and one or more additional sensing reports from other UE.

Abstract: Independent ranging sessions that are initiated by multiple initiating user equipments (UEs) are monitored and combined into a single combined ranging session to reduce overhead. A UE monitors a first set of ranging sessions initiated by a first initiator UE, which include pre-ranging messages identifying UEs in the first set of ranging sessions, and monitors a second set of ranging sessions initiated by a second initiator UE, which include pre-ranging messages identifying UEs in the second set of ranging sessions. The UE initiates a third set of ranging sessions by broadcasting pre-ranging messages identifying UEs in the third set of ranging sessions that comprises the UEs in the first set of ranging sessions and the UEs in the second set of ranging sessions. The original initiator UEs, upon receiving the pre-ranging messages initiating the third set of ranging sessions, terminate the initiation of their ranging sessions.

Abstract: A user equipment (UE) in a vehicle (V-UE) broadcasts multi-phased ranging signals with which other entities may determine the range to the V-UE. The multi-phased ranging signals may include a first message, which may be broadcast in the Intelligent Transport System (ITS) spectrum, includes ranging information, such as a source identifier, location information for the broadcasting V-UE, and an expected time of broadcast of the ranging signal. The ranging signal may then be broadcast at the expected time and may include the source identifier. A second message, which be broadcast in the ITS spectrum, may include clock error information for the V-UE. A receiving entity may determine the range to the V-UE based on the time of arrival of the ranging signal and the expected time of transmission, as well as the clock error information. The receiving entity may further generate a position estimate based on the received location information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a plurality of UEs for a UE positioning session. The UE may identify a set of parameters for the UE positioning session. The UE may broadcast information indicating at least the set of parameters for the UE positioning session. The UE may receive, from at least one of the plurality of UEs, a set of positioning reference signals (PRSs) based at least in part on the set of parameters. The UE may broadcast, based at least in part on the set of PRSs, positioning information. Numerous other aspects are provided.

Abstract: A method of wireless communication by a positioning entity includes determining an accuracy of a positioning estimate of a first non-anchor sidelink user equipment (UE). The method also includes determining the accuracy satisfies an accuracy condition. The method further includes configuring the first non-anchor sidelink UE as a first anchor UE based on the positioning estimate satisfying the accuracy condition.

Abstract: In a particular implementation, a method of wireless communication includes transmitting, from a first user equipment (UE) to a second UE, a radio resource control (RRC) request that includes a first discontinuous reception (DRX) preference at the first UE. The method also includes receiving, at the first UE from the second UE, a RRC setup message that includes a second DRX preference at the second UE. The method further includes transmitting, from the first UE to the second UE, a RRC setup complete message that includes an indication of a confirmed DRX cycle.

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: Techniques are provided for sidelink positioning with a single anchor using distributed antenna systems. An example method for determining relative locations of two stations includes determining a first round trip time for positioning reference signals transmitted between a first station and a first antenna of a second station, determining a second round trip time for the positioning reference signals transmitted between the first station and a second antenna of the second station, wherein the first antenna and the second antenna are disposed in different locations proximate to the second station, and determining relative locations of the first station and the second station based at least in part on the first round trip time and the second round trip time.

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.
