1. A method of wireless positioning performed by a user equipment (UE), the method comprising:
acquiring, from a first set of transmission/reception entities (TREs), a first set of measurements of signals, wherein a TRE comprises a base station, a UE, or a combination thereof;
selecting, from the first set of TREs, a second set of TREs, based on the first set of measurements of signals and criteria for selecting and/or prioritizing TREs for radio frequency fingerprint (RFFP)-based positioning, the criteria specifying a requirement for signal quality, anchor type, coverage status, or a combination thereof;
acquiring, from the second set of TREs, a second set of measurements of signals, the second set of measurements of signals comprising RFFP measurements; and
estimating a position of the UE based on the second set of measurements of signals.
