Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first information identifying a value for a threshold parameter associated with a sidelink positioning procedure. The mobile station may transmit second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may communicate with a second UE using a shared radio frequency spectrum band. The first UE may perform a listen before talk (LBT) and may transmit a first positioning reference signal (PRS) based on a result of the LBT. The first UE may transmit the first PRS using a first time resource that is based on a duration of the first PRS. In response to detecting the first PRS, the second UE may transmit a second PRS using a second time resource that is based on the duration of the first PRS. The second UE may transmit the second PRS based on performing an LBT without a random back-off, which may enable the second UE to transmit the second PRS with reduced latency and improved reliability.

Abstract: Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to perform groupcast transmission on a sidelink channel of a high frequency band, such as a millimeter wave (mmW) band. The UE may transmit, via a sidelink channel, beamformed repetitions of a packet in multiple directions corresponding to multiple quality of service (QoS) profiles configured for transmission of the packet. The UE may determine precoders to transmit the packet in the multiple directions. Each repetition of the packet may be associated with a separate hybrid automatic repeat request (HARQ) process. The UE may perform precoder cycling to transmit the packet in the multiple directions, and the UE may retransmit the packet in directions where the initial transmission was unsuccessful.

Abstract: Techniques are discussed herein for detecting anomalous signals such as spoofed satellite positioning system (SPS) signals and for the transmission of accurate location estimates between user equipments (UEs) when the SPS signals are not reliable. A UE determines an SPS derived location estimate and determines an associated confidence level. The confidence level is determined based on time or location derived from the SPS signals, e.g., relative to local time or non-SPS information, such as stored previous location estimates, non-SPS sensor information, and location information from other UEs. The UE transmits location information to other UEs that includes a selected location estimate, confidence level, and the source of the location estimate, e.g., where the SPS derived location estimate is selected if the confidence level is high and the non-SPS derived location estimate is selected if the confidence level is low.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a sidelink connection with a second UE, where the sidelink connection is associated with a plurality of flows. The first UE may determine, based on monitoring each flow of the plurality of flows, a radio link status of the sidelink connection. The first UE may transmit, based on the determining, a non-access stratum layer message to the second UE based at least on the radio link status of the sidelink connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit route information indicating a route associated with the UE. The UE may receive, based at least in part on transmitting the route information, configuration information indicating at least one other UE assigned to the UE for sidelink positioning. Numerous other aspects are described.

Abstract: A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.
