    Abstract: Aspects described herein relate to identifying a sidelink priority value of sidelink traffic to be transmitted via a sidelink channel, identifying a type of uplink traffic to be transmitted via an uplink channel, the uplink traffic is scheduled to be transmitted contemporaneously with the sidelink traffic, prioritizing, based at least in part on the identification of the type of uplink traffic being of a first type uplink traffic, the uplink traffic regardless of the sidelink priority value, and transmitting, based on prioritizing the sidelink traffic or prioritizing the uplink traffic, at least one of the sidelink traffic or the uplink traffic.

    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: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

    Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host wireless device may transmit a discovery message to a client wireless device. The client wireless device may transmit a random access channel (RACH) preamble on a first time domain resource to the host wireless device in response to the discovery message. The client wireless device may later transmit a second RACH message to the host device on a second time domain resource after the first time domain resource. The second time domain resource may be defined by a mapping from the first time domain resource. The host device may transmit a third RACH message establishing a communication session between the host wireless device and the client wireless device.

    Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

    Abstract: Methods and apparatuses are provided for use in wireless communication devices to provide a capability for vehicles to actively perform traffic planning with regard to other vehicles, for example, within a region comprising an intersection and possibly wherein the intersection is not associated with a device or service for such or similar purposes. Such underlying techniques may reduce traffic congestion in certain instances by allowing two or more vehicles to negotiate or otherwise coordinate safe traversal within a region comprising an intersection. Moreover, the traffic planning techniques may be of use for a variety and/or mixture of different types of vehicles, paths, intersections, etc.
