Multiple user equipments (UEs) may initiate independent ranging sessions at approximately the same time and location and may interfere with each other. A UE receiving multiple initial messages for ranging determines whether there is a time separation between the ranging sessions. The UE may further determine whether there is a geographic separation between the ranging sessions, for example, whether the initiating UEs are separated. If there is no separation, the UE separates available ranging signal characteristics, such as frequency bandwidth, timing instance, and identifier, and communicates a different set of ranging signal characteristics to each initiating UE. Multiple ranging sessions may be conducted using different sets of ranging signal characteristics without much risk of interference.
