Abstract

See full text

Multiple user equipments (UEs) may initiate independent ranging sessions at nearly the same time and location and which may interfere with each other. A UE that receives multiple initial messages for ranging determines if there is temporal separation between the ranging sessions. The UE may further determine if there is geographic separation between the ranging sessions, e.g., the initiating UEs are separated. If separation is lacking, the UE separates available ranging signal properties, such as frequency bandwidth, timing instances, and identifiers, and communicates different sets of ranging signal properties to each initiating UE. The multiple ranging sessions may be performed using the different sets of ranging signal properties with less risk of interference.
