1. A method of ranging between user equipments (UEs) performed by a receiving UE, the method comprising:
receiving a first initial message from a first UE to initiate a first ranging session;
receiving a second initial message from a second UE to initiate a second ranging session;
determining that a temporal separation between the first ranging session and the second ranging session is less than a predetermined time threshold;
separating available ranging signal properties into a first set for the first ranging sessions and a second set for the second ranging session, wherein the first set of ranging signal properties and the second set of ranging signal properties are different;
transmitting a first response messages to the first UE comprising the first set of ranging signal properties and a second response message to the second UE comprising the second set of ranging signal properties; and
performing the first ranging session with the first UE using the first set of ranging signal properties and the second ranging session with the second UE using the second set of ranging signal properties.
