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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, periodically, at least one metric associated with a current reference signal on a sidelink. Accordingly, the UE may extend a time window allowed for a search for a new reference signal on the sidelink based at least in part on the at least one metric. For example, the UE may extend the time window as a function of a discontinuous reception cycle associated with the UE. Alternatively, the UE may extend the time window for a preconfigured amount of time. Numerous other aspects are described.

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: 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: 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 user equipment (UE) may reserve a transmission resource for transmitting a transmission block (TB) via a sidelink communication; reserve a retransmission mission resource for retransmitting the TB, wherein the retransmission resource is reserved such that at least one hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback occasion occurs between transmission of the TB and a first retransmission of the TB; and communicate with another UE via the sidelink communication based at least in part on the transmission and retransmission resources. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically scheduling antenna resources of a wireless node, such as, antenna panels of a user equipment (UE). In some cases, a first node (e.g., a UE) performs, with two or more other nodes, a first beam sweep procedure across two or more antenna resources of the first node on two or more wireless interfaces, generates or obtains scheduling information based on results of the first beam sweep procedure, wherein the scheduling information indicates which of the antenna resources is scheduled for which wireless interfaces, and communicates with the other nodes on the wireless interfaces according to the scheduling information.

Abstract: The base station may transmit a mode switch indication to a UE to switch from a first duplex mode to a second duplex mode. The UE may activate or deactivate one or more antenna panels and the UE and the base station may communicate with each other based on the mode switch indication. The second duplex mode may be FD mode, and the mode switch indication may be transmitted a threshold number of symbols or slots prior to the FD symbols. The slot format pattern may not include FD symbol, and the base station and the UE may communicate bidirectional signals in FD mode using the flexible symbols. The second duplex mode may be HD mode. The slot format pattern may include the FD symbols, and the base station and the UE may transmit or receive signals in HD mode using the FD symbols as the flexible symbols.
