Constraints on a source reference signal for quasi-collocation timing reference of a positioning reference signal

A method of a network entity, the method comprising:

• determining whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, wherein the source reference signal is a first downlink positioning reference signal transmitted on a first downlink transmit beam and the target reference signal is a second downlink positioning reference signal transmitted on a second downlink transmit beam, and wherein it is determined that the source reference signal is the QCL source of the target reference signal based on the source reference signal and the target reference signal satisfying a BW constraint specifying that a first BW portion and the second BW portion be within a threshold distance of each other in a frequency domain;
• and
• configuring a user equipment (UE) with the source reference signal as the QCL source of the target reference signal based on a determination that the source reference signal is the QCL source of the target reference signal.
