A method for a Round Trip Time, RTT, measurement procedure performed in a communication network, the network comprising a location server, LS, at least one user equipment, UE, a serving radio base station, s-gNB, serving the UE, and a number of neighboring radio base stations, n-gNBs, the method comprising: identifying, by the LS, said n-gNBs, based on at least one report from said at least one UE, or from UE information based on at least one measurement performed by said s-gNB; initiating, by the LS, configuration by: o acquiring capabilities of said at least one UE and capabilities from said gNBs, o acquiring beam measurements for the s-gNB and n-gNBs from said at least one UE report or from UE information based on measurements performed by the s-gNB and the n-gNBs; o informing said UE about resources for the s-gNB and the n-gNBs; o setting one of said UEs or gNBs to an initiator, and setting the rest of said UEs and gNBs to responders; and o providing initiator/responder frequency and time resources and group shared resources; and performing, by the LS, signaling and measurements by: o associating at least one positioning reference signal, PRS, from said initiator with receiving responders, wherein said PRS is an UL-PRS if said initiator is a UE, and a DL-PRS if said initiator is a gNB, o receiving from said responders a PRS on said specified frequency and time resources; and o measuring the timing information corresponding to the signal received from the initiator. identifying, by the LS, said n-gNBs, based on at least one report from said at least one UE, or from UE information based on at least one measurement performed by said s-gNB; initiating, by the LS, configuration by: o acquiring capabilities of said at least one UE and capabilities from said gNBs, o acquiring beam measurements for the s-gNB and n-gNBs from said at least one UE report or from UE information based on measurements performed by the s-gNB and the n-gNBs; o informing said UE about resources for the s-gNB and the n-gNBs; o setting one of said UEs or gNBs to an initiator, and setting the rest of said UEs and gNBs to responders; and o providing initiator/responder frequency and time resources and group shared resources; and o acquiring capabilities of said at least one UE and capabilities from said gNBs, o acquiring beam measurements for the s-gNB and n-gNBs from said at least one UE report or from UE information based on measurements performed by the s-gNB and the n-gNBs; o informing said UE about resources for the s-gNB and the n-gNBs; o setting one of said UEs or gNBs to an initiator, and setting the rest of said UEs and gNBs to responders; and o providing initiator/responder frequency and time resources and group shared resources; and performing, by the LS, signaling and measurements by: o associating at least one positioning reference signal, PRS, from said initiator with receiving responders, wherein said PRS is an UL-PRS if said initiator is a UE, and a DL-PRS if said initiator is a gNB, o receiving from said responders a PRS on said specified frequency and time resources; and o measuring the timing information corresponding to the signal received from the initiator. o associating at least one positioning reference signal, PRS, from said initiator with receiving responders, wherein said PRS is an UL-PRS if said initiator is a UE, and a DL-PRS if said initiator is a gNB, o receiving from said responders a PRS on said specified frequency and time resources; and o measuring the timing information corresponding to the signal received from the initiator. <EOS>
