Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a sidelink communication. The UE may generate a transmit power control command based at least in part on a measurement of the sidelink communication. The UE may transmit, via a sidelink feedback channel, the transmit power control command to control a transmit power, for another sidelink communication, of the source UE. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) participating in a sidelink communications group communicates with one or more member UEs of the sidelink communications group, and transmits group presence announcement messages for the sidelink communications group based on a determination, based on communicating with the one or more member UEs, of at least a transmit power for the group presence announcement messages and that the UE is expected to transmit the group presence announcement messages for the sidelink communications group.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), an indication of an access link discontinuous reception (DRX) configuration and a sidelink DRX configuration. The access link DRX configuration and the sidelink DRX configuration may synchronize access link DRX operation and sidelink DRX operation of the UE. The UE may perform access link communication with the BS based at least in part on the access link DRX configuration and/or may perform sidelink communication with another UE based at least in part on the sidelink DRX configuration. Numerous other aspects are provided.

Abstract: Techniques for wireless communications are described. A first device may receive first control signaling that may indicate a second device in a wireless communications system. The first device may then identify, based on the received first control signaling, a set of devices for tracking the second device in the wireless communications system. In some examples, the first device may then transmit second control signaling to the identified set of devices for tracking the second device in the wireless communications system. The first device may then receive, based on the transmitted second control signaling, coordination information from the set of devices. The received coordination information may be associated with the second device. The coordination information collected by the set of devices may be used to predict changes in an environment surrounding the second device. By predicting dynamic changes in the environment, disruptions in wireless communication may be prevented.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

Abstract: Certain aspects of the present disclosure provide techniques relating to network controlled sensor information sharing between vehicles. In one embodiment, a method of wireless communications by a network entity comprises receiving a request, from a first user equipment (UE), for sharing of sensor information by at least a second UE based on a target region indicated by the request and taking one or more actions, in response to the request, to trigger the sharing of sensor information by the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), such as a pedestrian UE, may perform a discovery procedure with a second UE in a vehicle-to-everything (V2X) wireless communications environment that includes multiple other UEs in addition to the first UE and the second UE. The second UE may, for example, be a roadside UE configured to aggregate V2X messages for the first UE. The first UE may determine, based on performing the discovery procedure, a schedule for the first UE to use to receive bundled V2X messages from the second UE. The first UE may receive, from the second UE based on the determined schedule, a message indicating bundled information from multiple V2X messages received at the second UE from the multiple UEs.

Abstract: In an aspect, a vehicle apparatus of a vehicle obtains, based on sensor data from one or more vehicle sensors communicatively coupled to the vehicle, intra-lane position data relative to the vehicle, the intra-lane position data indicating at least one lateral distance between at least one side of a primary vehicle and at least one lane reference point. The vehicle apparatus transmits the intra-lane position data to one or more neighboring entities. In another aspect, a vehicle management device obtains intra-lane position data that indicates at least one lateral distance between at least one side of at least one observed vehicle of a plurality of neighboring vehicles and at least one lane reference point, and instructs at least one vehicle of the plurality of neighboring vehicles to perform one or more actions based on the intra-lane position data.
