Abstract: Aspects relate to techniques for enabling a UE to detect a potential mistrusted UE that may be sharing inaccurate sidelink assistance information with other UEs. In an aspect, a first UE may receive a plurality of sidelink assistance information from other UEs. The first UE can further identify an amount of the plurality of sidelink resources for which a second UE provides respective inconsistent sidelink assistance information with respect to other UEs. In response to the amount exceeding a mistrust detection threshold, the first UE can transmit a report indicating that the second UE is a potential mistrusted UE to a centralized node. Based on the received reports associated with the second UE, the centralized node can transmit a mistrust indication indicating that the second UE is an actual mistrusted UE with respect to subsequent sidelink assistance information associated with the second UE.

Abstract: A network device is provided with excessive interference mitigation. In one implementation, the network device transmits a notification of the excessive interference to a network entity. In another implementation, the network device changes a receive beam or begins to acquire a new cell in response to a detection of the excessive interference. In yet another implementation, the network device alerts a user in response to a detection of the excessive interference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, radio resource control (RRC) signaling configuring a list of sidelink transmission configuration indication (TCI) states. The UE may communicate on one or more sidelink channels using one or more sidelink TCI states included in the list of sidelink TCI states configured in the RRC signaling. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of a range of frequencies outside an operational bandwidth of the UE based at least in part on the range of frequencies being compatible with one or more sets of analog beamforming beam weights associated with the operational bandwidth. The UE may communicate, with the base station, based at least in part on transmitting the indication of the range of frequencies outside of the operational bandwidth of the UE. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit at least a first synchronization signal block (SSB) over a first sub-band in a first spatial direction and a second SSB over a second sub-band in a second spatial direction, wherein the at least the first SSB and the second SSB are transmitted at a same time and wherein the at least the first SSB and the second SSB comprise a set of SSBs, the at least first sub-band and the second sub-band comprise a first set of sub-bands, and the at least first spatial direction and the second spatial direction comprise a first set of spatial directions.

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.
