The location management function may derive, from the sensing-based observation, a position hypothesis and may determine, from the reference-signal-based observation, UE identity information for the UE. By processing the reference-signal-based observation in conjunction with the sensing-based observation, the location management function may determine an association between the sensing-based observation and the reference-signal-based observation. The location management function may then transmit, to the UE having the UE identity information determined from the reference-signal-based observation, an indication of the position hypothesis derived from the sensing-based observation. ## Claims ### Claim 1 A method of indicating a location of a first device, the method comprising: obtaining, from a profile origin, a sensing-based profile including a sensing-based observation of the first device;
