Abstract: A responder user equipment (UE) in separate ranging sessions may determine whether there is a collision between the ranging signals assigned to broadcast in the separate ranging sessions. A collision in the ranging signals is detected when the ranging signals have the same frequencies and broadcast times, e.g., the broadcast time of one ranging signal is within a predetermined amount of time for the other ranging signal. When a collision in the ranging signals is detected, the responder UE sends a message to the initiator UE indicating the possibility of a collision. Available times for broadcasting the ranging signals may be determined, e.g., by the responder UE or the initiator UE. The initiator UE may initiate a new ranging session based on the available times for broadcasting the ranging signal or may proceed with the ranging session with the possibility that the responder UE will not participate.

Abstract: Multiple user equipments (UEs) may initiate independent ranging sessions at nearly the same time and location and which may interfere with each other. A UE that receives multiple initial messages for ranging determines if there is temporal separation between the ranging sessions. The UE may further determine if there is geographic separation between the ranging sessions, e.g., the initiating UEs are separated. If separation is lacking, the UE separates available ranging signal properties, such as frequency bandwidth, timing instances, and identifiers, and communicates different sets of ranging signal properties to each initiating UE. The multiple ranging sessions may be performed using the different sets of ranging signal properties with less risk of interference.

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: 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: Aspects relate to group-based positioning reference signal (PRS) broadcast in a wireless communication network. Wireless communication devices communicating over a sidelink channel in the wireless communication network may be grouped into one or more positioning groups. Within each positioning group, a respective order of the wireless communication devices in the positioning group may be identified. The wireless communication devices in a positioning group may then communicate PRSs therebetween over the sidelink channel based on the order of wireless communication devices in the positioning group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an initiator UE, a group formation communication indicating a group that the UE is associated with for a group positioning reference signal (PRS) Listen Before Talk (LBT) procedure. The UE may transmit, to the initiator UE, an indication that the UE should not be associated with the group based at least in part on performing the group PRS LBT procedure. Numerous other aspects are provided.

Abstract: A user equipment in a vehicle (V-UE) may transmit ranging signals, for example positioning reference signals (PRS), via inter-vehicle messages. The broadcast parameters for the ranging signals, such as the timing of transmission, the bandwidth, or a combination thereof, may be adjusted based on one or more motion characteristics of the vehicle. If high speed or large acceleration, or rate of turning, is detected, the rate of transmission and/or the resource blocks included in the ranging signals may be increased. By increasing the rate of transmission and/or recourse blocks in the ranging signals, other vehicles receiving the ranging signals may update the range more often and with greater accuracy for increased safety while the transmitting vehicle is traveling at high speeds or acceleration.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, using a set of receive antennas, a first positioning reference signal (PRS). The first UE may transmit, using a set of transmit antennas in response to the received first PRS, a second PRS. The first UE may receive, from a second UE, a control message indicating time and position information for the first PRS transmitted by the second UE and for the second PRS received at the second UE. The first UE may determine a position of the first UE based on the received control message and composite time and position information for the first PRS received at the first UE and for the second PRS transmitted by the first UE.
