(54) Title: CONFIGURING MULTI-CHANNEL TRANSMISSION FOR RANGING ACCURACY (57) : Methods, systems, and devices for wireless communication are de- scribed. A wireless device may identify a configuration for transmitting ranging sig- nals 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. 210 2 220 zoo FIG. 2 W O 20 18/ 19098 2 Al [Continued on next page] WO 2018/190982 Al MIDEDIMOMOIDEIREEMOMOIMMENBUDIMIE Published: — with international search report (Art. 21(3))
