Bandwidth indication in positioning measurement reports
Disclosed are techniques for wireless communication. In an aspect, a UE or base station performs, during a positioning session, a measurement of a first positioning reference signal (PRS) within a first bandwidth part (BWP), performs, during the positioning session, a measurement of a second PRS within a second BWP, transmits, to a location server, a measurement report including the measurement of the first PRS and the measurement of the second PRS, and transmits, to the location server, an indication of the first BWP, the second BWP, or both.
