    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for transmitting ranging signals in a vehicle-based communication system. The configuration may identify a plurality of channels to be used for the ranging signals and timing for the ranging signals. The wireless device may transmit the configuration to a receiver and transmit ranging signals based at least in part on the configuration. The receiver may use the ranging signals to determine a distance between the receiver and the wireless device. The receiver may use the determined distance to update positioning information or operate a motor vehicle.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with minimizing D2D RTS/CTS signaling overhead resource usage. In one example, a WAN entity is equipped to receive one or more channel gain values from a plurality of UEs, determine that a CID can be reused by multiple D2D links based on the received one or more channel gain values, and transmit information indicating that the CID may be reused. In another example, a UE is equipped to measure a direct power signals and an inverse power echoes on a CID used for a link formed between a third and fourth UE, and determine that the CID may potentially be reused by a link formed with a second UE for D2D RTS/CTS signaling, based at least in part on the measured direct power signals, measured the inverse power echoes, and a SIR threshold.
