Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect an object and determine to share position information associated with the object with one or more UEs. The UE may select a reference entity detectable by one or more other UEs and determine the position of the detected object relative to the position of the selected reference entity. The UE may transmit, to one or more second UEs, a sensor sharing message that includes the position information of the object relative to the selected reference entity and an indication of the selected reference entity. The one or more second UEs may detect the position of the reference entity and determine the location of the detected object based on the position of the reference entity and the position of the detected object relative to the position of the reference entity.

Alternative coordinate system for sensor sharing

Methods, systems, and devices for wireless communications are described. In some cases, an application enabler layer (e.g., a vehicle-to-everything (V2X) application enabler (VAE) layer), may identify a congestion control configuration that includes capabilities for collecting operation information. The application enabler layer may receive, from a set of user equipment (UEs), the operation information in accordance with the capabilities. Then, the application enabler layer may generate congestion control instructions for one or more UEs of the set of UEs based on the received operation information. Additionally or alternatively, an application enabler architecture layer (e.g., a service enabler architecture layer for verticals (SEAL)) may identify a congestion control configuration including capabilities for collecting operation information and monitor sidelink performance for the set of UEs in accordance with the capabilities. The application enabler architecture layer may identify a congestion status for a communication type based on monitoring the sidelink performance.

Congestion control by a sidelink midlayer framework

Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an aspect, an application layer in a user equipment (UE) receives, from an access layer in the UE, a quality of service (QoS) indication comprising a metric that represents a quality of one or more radio bearers used for a vehicular communication with one or more other UEs. The application layer performs a transmission control over the vehicular communication based on the QoS indication.

Transmission control in application layer based on radio bearer quality metrics in vehicular communication

Techniques described herein provide for leader selection of a group of vehicles, based on inter-vehicle communications. According to embodiments, a host vehicle can determine it qualifies to be the leader of a potential group by comparing vehicle information of other cars in the potential group with its own vehicle information. Once the determination has been made, the host vehicle can then send a request to be the group leader to the other vehicles. If the other vehicles accept, the host vehicle can initiate group formation. Otherwise, another vehicle can reject the request and send its own request to become the group leader, reinitiating group leader negotiation until a group leader is determined.

Leader selection in V2X group management

Methods, systems, and devices for wireless communications are described. A user equipment (UE) that transmits sensor data to another UE may also send information about the associated sensor and its performance. For example, the UE may determine a set of rules that apply to a sensor. The set of rules may define an association between a group of performance values and a group of performance levels corresponding to one or more metrics of the sensor. The UE may identify a performance value from the group of performance values for the sensor based on a performance level of the sensor and the set of rules. After determining the performance value, the UE may transmit an indication of the set of in a first data frame of a message and an indication of the performance value in a second data frame of the message.

Sensor performance indication

Methods and systems for managing traversals of one or more vehicles through a traffic intersection are proposed. In one example, a method comprises: receiving a first message including one or more motion characteristics of one or more vehicles approaching the traffic intersection; forming a motion group; grouping a subset of the one or more vehicles into the motion group based on the one or more motion characteristics; assigning a leader vehicle for the motion group; determining a group maneuver target for the motion group to traverse through the traffic intersection; and transmitting, to the leader vehicle of the motion group, a second message including the group maneuver target for the motion group, to enable the leader vehicle of the motion group to control a motion of each member vehicle of the motion group based on the group maneuver target.
