1. A method comprising:
receiving, by a user equipment (UE), beamformed position reference signals (BF-PRSs) on a plurality of beams from a plurality of network devices in accordance with a BF-PRS configuration;
measuring, by the UE, a time difference (TD) between a pair of BF-PRSs of the BF-PRSs received from a pair of network devices of the plurality of network devices; and
transmitting, by the UE, a feedback message indicating the TD, the feedback message including identification information identifying the pair of network devices.
