Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may establish, via a sidelink signaling interface, a unicast link between the remote UE and a relay UE; establish a connection with a base station via the relay UE, wherein a message associated with establishing the connection is communicated via the unicast link; establish one or more bearers based at least in part on a radio bearer configuration received from the base station via the connection; establish, with the relay UE, one or more sidelink access stratum entities for the one or more bearers using one or more sidelink radio resource control messages based at least in part on an access stratum configuration received from the base station via the connection; and receive or transmit control-plane or user-plane traffic via the one or more bearers.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) receives device-to-device (D2D) information from a second user equipment (UE). The first UE determines whether the first UE is within a threshold range from the second UE based on the D2D information. Application layer processing is enabled for a message in the D2D information, if the first UE is within the threshold range.

Abstract: Techniques described herein leverage existing localization sensors or V2X devices to detect one or more other vehicles that include wireless systems that can interfere with in-vehicle wireless networks. The localization sensors or V2X devices can provide information to determine a location, a heading, a speed, a size, and a type of other vehicles. This information can be used to determine a probability of network interference and allow the in-vehicle wireless networks to employ one or more techniques to mitigate the effects of the interference. The interference mitigation techniques can include increasing or decreasing transmitter power, changing a frequency or a channel of a wireless transmitter, or activating one or more additional transmitters as relays to improve reliability.

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, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switched from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting one or more sidelink channel state information (CSI) reference signals (CSI-RSs) targeting a group of user equipments (UEs). The method generally includes requesting one or more CSI reports from a selected one or more UEs of the group of UEs. The method generally includes receiving one or more CSI reports from the selected one or more UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine a link quality for one or more links associated with the first UE. A link quality for a link of the one or more links may be based at least in part on one or more measurements associated with at least a subset of a plurality of beams of the link. The first UE may generate, based at least in part on the link quality for the one or more links associated with the first UE, a connectivity graph of at least a portion of a wireless network in which the first UE is included. The first UE may identify, using the connectivity graph, a route to a third UE included in at least the portion of the wireless network. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source user equipment (UE) may transmit a first sidelink communication to a target UE. The source UE may receive, based at least in part on transmitting the first sidelink communication to the target UE, a transmit power control command for a second sidelink communication. The source UE may transmit the second sidelink communication using a transmit power determined based at least in part on the transmit power control command. 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 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.
