Claim 0:
1. A method performed by a positioning entity, comprising:
obtaining a plurality of transmission-reception point (TRP) round trip time (RTT) related measurements, the plurality of TRP RTT-related measurements being one-to-one associated with a plurality of TRPs, wherein each TRP RTT-related measurement is associated with one TRP of the plurality of TRPs;
obtaining a plurality of user equipment (UE) RTT-related measurements, wherein each of the plurality of UE RTT-related measurements is associated with one TRP of the plurality of TRPs; and
determining a position of a UE based on the plurality of TRP RTT-related measurements and the plurality of UE RTT-related measurements,
wherein for each TRP of the plurality of TRPs,
the TRP RTT-related measurement associated with that TRP represents a duration between that TRP transmitting a downlink reference signal (DL RS) to the UE and that TRP receiving a corresponding uplink reference signal (UL RS) from the UE, and
the UE RTT-related measurement associated with that TRP represents a duration between the UE receiving the DL RS from that TRP and the UE transmitting the corresponding UL RS to that TRP,

wherein for each TRP k,
the associated TRP RTT-related measurement is expressed as ΔgNBk=TgNB,Rxk−TgNB,Txk in which TgNB,Txk represents a transmission time of the DL RS from that TRP and TgNB,Rxk represents a reception time of the corresponding UL RS at that TRP, and
the associated UE RTT-related measurement is expressed as ΔUEk=TUE,Rxk−TUE,Txk in which TUE,Rxk represents a reception time of the DL RS at the UE and TUE,Txk represents a transmission time of the corresponding UL RS from the UE,

wherein the plurality of TRP RTT-related measurements comprise quantities one ΔgNB1, zero or more ΔgNB2, and zero or more ΔgNB3 such that a total number of TRP RTT-related measurements is two or greater, the ΔgNB1 corresponding to a primary TRP in data communication with the UE, each ΔgNB2 corresponding to each secondary TRP in data communication with the UE, and each ΔgNB3 corresponding to a neighboring TRP not in data communication with the UE, and
wherein the plurality of UE RTT-related measurements comprise quantities one ΔUE1, zero or more ΔUE2, and zero or more ΔUE3 such that a total number of UE RTT-related measurements is two or greater, the ΔUE1 corresponding to the primary TRP, each ΔUE2 corresponding to each secondary TRP, and each ΔUE3 corresponding to each neighboring TRP.
