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: An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS). A first packet can be obtained, by a wireless communications device, from an application generated for a radio access technology (RAT), where the first packet includes a QoS value associated with the RAT. A reflective indicator can be set in a header of the first packet to indicate a configuration, including a QoS value, to be used by a receiving device in transmitting a second packet. The first packet can be transmitted to the receiving device.

Abstract: Various aspects described herein relate to techniques for connection setup procedures in a wireless communication system (e.g., a vehicle-to-everything (V2X) communication system in millimeter wave). In an aspect, the method includes identifying information for V2X communications, and initiating a random access procedure based on the identified information. The method further includes identifying one or more random access channel (RACH) resources based on the information, identifying one or more RACH response resources based on the one or more RACH resources, and performing directional communications using at least the one or more RACH resources or the one or more RACH response resources.

Abstract: Techniques are provided for supporting V2X communications which may be implemented in various apparatuses, methods, and/or articles of manufacture. In certain aspects an extended transmission profile may be determined to support V2X communications via 5G NR RATs between two or more wireless devices. For example, one or more processing units of a wireless device may determine that a NR RAT is requested for a V2X communication based, at least in part, on service information associated with data to be transmitted, determine an extended Tx Profile for the V2X communication, and initiate transmission of at least a portion of the data via the NR RAT using the transceiver based on the extended Tx Profile.

Abstract: A method, a computer-readable medium, and an apparatus for V2V, V2X, or D2D communication may be a transmitting device configured to determine a source ID for communication over a link, to determine a destination ID for the communication over the link based on a type of the communication. The transmitting device may be further configured to transmit at least one control message over the link, where the control message(s) indicate the source ID and the destination ID. In certain aspects, a receiving device may be configured to receive the control message over the link, where the control message indicates the source ID and the destination ID. The receiving device may be configured to receive a data message over the link and to determine whether to attempt to decode the data message received over the link based on the source ID and the destination ID indicated in the control message.
