Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.

Abstract: Disclosed are some examples of techniques for positioning of a user equipment (UE) using positioning reference signal (PRS). One or more units of messages may be communicated between an initiator UE and a responder UE. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include one or more of a direction, a velocity, a location confidence and a location of the responder UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) message, the RRC message including an indication of whether group-based beam reporting is enabled for the UE. The UE may transmit a group-based beam report based at least in part on the indication that the group-based beam reporting is enabled for the UE. Numerous other aspects are described.

Abstract: Independent ranging sessions that are initiated by multiple initiating user equipments (UEs) are detected and combined into a single combined ranging session to reduce overhead. The independent ranging sessions may be determined to be nearby and concurrent when a UE detects a number of ranging cycles within a predetermined time. The UE may send messages to each initiator UE indicating that the ranging sessions should be combined and the initiator UEs will terminated initiating any further ranging sessions. Combined ranging session may be initiated by the UE and may include all of the participating UEs from the independent ranging sessions. The combined ranging session continues until it is determined that one or more UEs in the combined ranging session are not receiving ranging signals from other UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.
