    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: 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: The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a remote user equipment (UE) may transmit, on at least one sidelink channel, a scheduling request to a relay UE connected with a network entity. The remote UE may further receive, on one or more sidelink channels, a scheduling indication including a resource grant from the relay UE in response to transmitting the scheduling request. In a further aspect, a relay UE may receive, on at least one sidelink channel, a scheduling request from a remote UE. The relay UE may further determine, a resource grant for the remote UE in response to receiving the scheduling request. The relay UE may further transmit, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.

    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.

    Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host device may determine a pool of preconfigured resources for discovery. The preconfigured resources are designated for one or more of: a discovery preamble, a query signal, a discovery message, and a random access preamble. The host device may transmit the discovery preamble on one or more resources designated for the discovery preamble. A client device may receive the discovery preamble and determine that the client device is interested in receiving information regarding the host device. The client device may transmit a query signal if interested. The host device may determine whether the query signal is received on a resource designated for the query signal in response to the discovery preamble. The host device may transmit a discovery message in response to receiving the query signal.

    Abstract: A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.
