    Abstract: A UE transmits, to at least one UE, a PRS request message, the transmitted PRS request message including one or more parameters including at least one of: an SL ranging protocol version, one or more supported PRS channels, a supported per-channel PRS bandwidth, an initiator UE-assigned PRS Tx time, or a post-PRS Tx time. The UE receives, from the at least one UE, a PRS response message based on the transmitted PRS request message. The UE transmits, to the at least one UE, a PRS confirmation message based on the received PRS response message, the transmitted PRS confirmation message including one or more parameters including at least one of: the SL ranging protocol version, the one or more supported PRS channels, the supported per-channel PRS bandwidth, the initiator UE-assigned PRS Tx time, or the post-PRS Tx time.

    Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

    Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

    Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine a link quality for one or more links associated with the first UE. A link quality for a link of the one or more links may be based at least in part on one or more measurements associated with at least a subset of a plurality of beams of the link. The first UE may generate, based at least in part on the link quality for the one or more links associated with the first UE, a connectivity graph of at least a portion of a wireless network in which the first UE is included. The first UE may identify, using the connectivity graph, a route to a third UE included in at least the portion of the wireless network. Numerous other aspects are provided.

    Abstract: Certain aspects of the present disclosure to techniques for sidelink re-discovery without repeating beamforming in millimeter wave (e.g., Frequency Range 2) bands. For example, a Tx UE may complete a first beam training with a Rx UE. The Tx UE may generate a discovery message that includes at least one of: an indication of a beam training reference signal (BT-RS) sequence index of the first beam training; an indication of a timer for changing the BT-RS sequence; or an indication of a second BT-RS sequence to be used by the Tx UE before an expiration of the timer. The second BT-RS sequence may be indicated as an index to a set of BT-RS sequences including the BT-RS sequence associated with the first beam training. The Tx may transmit the generated discovery message to the Rx UE.

    Abstract: A configuration for allowing a wireless device to request control of another wireless device. The apparatus receives a message from a first user equipment (UE), the message comprising a first identifier (ID). The apparatus sends a first request to an authority requesting authorization to control the first UE. The apparatus receives information from the authority for controlling the first UE. The apparatus transmits a second request for connection with the first UE to control the first UE, the second request comprising the information received from the authority.
