Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

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 provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving one or more configurations for sidelink discontinuous reception (SL DRX); determining an SL DRX pattern for a communication on the sidelink, based on the one or more configurations for DRX, the communication comprising a service for broadcast communication, a group of UEs for groupcast communication, or a UE pair for unicast communication; and communicating with one or more other UEs on the sidelink using the determined SL DRX pattern.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a service type to be used by the UE for one or more device-to-device (D2D) communications on a sidelink interface; determine a slice identifier based at least in part on the service type, wherein the slice identifier corresponds to a resource allocation to be used for the one or more D2D communications; and transmit an indication of the slice identifier. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may then be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.

Abstract: Techniques are disclosed for a priori or real-time intersection trajectory determination of a vehicle, and corresponding messaging of the trajectory determination. Trajectory determination may be based on vehicle static characteristics, dynamic characteristics, and/or intersection geometry. Trajectory messages, which can be communicated using CV2X, may not only indicate the trajectory, but may (optionally) indicate which intersection ingress and egress points the vehicle will block over the course of the traversal of the vehicle along the trajectory.
