Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

Abstract: A method of triggering a distance-based feedback transmission in a vehicle communication system includes determining an availability of the location information of a first electronic device, and transmitting sidelink control information that indicates the availability of the location information of the first electronic device. The sidelink control information includes a communication range indication or another parameter indicating the availability of the location information of the first electronic device. A receiving device receives the sidelink control information from the first electronic device, determines based on the sidelink control information that the location information of the first electronic device is unavailable, and transmits a distance-based feedback message to the first electronic device based at least in part on the sidelink control information.

Abstract: Aspects relate to mechanisms for a wireless communication device to generate a superposition transmission of a sidelink signal to be transmitted to at least one receiving wireless communication device and an uplink signal to be transmitted to a base station. The wireless communication device may transmit the superposition transmission on resources allocated by the base station on a common carrier utilized for both sidelink and uplink transmissions. The superposition transmission includes a base layer corresponding to the uplink signal and an enhanced layer corresponding to the sidelink signal. The wireless communication device may further generate and transmit interference assistance information to the receiving wireless communication device for use by the receiving wireless communication device in canceling the base layer from the superposition transmission.

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: Various aspects of the present disclosure generally relate to roadside unit relay for sidelink communications. In some aspects, a user equipment (UE) may determine a resource in which to monitor for a message from a wireless communication device, where the message is based at least in part on information from one or more vehicle to everything (V2X) messages received by the wireless communication device. The UE may monitor for the message only in the resource and receive the message in the resource. Numerous other aspects are provided.

Abstract: Aspects relate to wireless communication devices configured to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a first sidelink transmission, determine one or more sidelink resources for receiving a second sidelink transmission based at least in part on the resources used to transmit the first sidelink transmission, monitor the determined one or more sidelink resources, and receive via the transceiver the second sidelink transmission on the monitored one or more sidelink resources. According to another example, a wireless communication device can receive a first sidelink transmission, determine one or more sidelink resources for transmitting a second sidelink transmission based at least in part on the received first sidelink transmission, and transmit the second sidelink transmission on the one or more of the determined sidelink resources.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.

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.
