Interference avoidance for ranging and positioning of distributed devices
Disclosed are some examples of techniques for ranging and positioning of distributed devices to avoid local and/or periodic interference. For example, an initiator user equipment (UE) can broadcast a positioning reference signal (PRS) message of a current positioning session to responder UEs. One or more characteristics of PRS transmission associated with a first responder UE in the current positioning session can be determined. Based on the characteristic(s), interference with the first responder UE can be identified, which can cause the initiator UE to change the broadcast order of the responder UEs for a next positioning session.
