A method for determining multiple round-trip times, RTTs, for a user equipment, UE, performed by a serving New Radio, NR, Node B, gNB, for the UE, the method comprising: sending, by the serving gNB to the UE, a control signal indicating that the serving gNB and a plurality of other nodes will be transmitting a plurality of RTT measurement signals during a plurality of predefined symbols of downlink subframes, wherein the control signal further requests the UE to report the information indicative of an arrival time at the UE of each of the plurality of RTT measurement signals; sending, by the serving gNB to the UE, during one or more predefined symbols of a downlink subframe, an RTT measurement signal on a cell supported by the serving gNB, wherein the plurality of RTT measurement signals comprise the RTT measurement signal and the plurality of other RTT measurement signals transmitted by the plurality of other nodes; receiving, at the serving gNB from the UE, an RTT response signal, wherein the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals is included in a payload of the RTT response signal, and wherein reception of the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals comprises decoding the payload for the RTT response signal; obtaining, by the serving gNB, an arrival time at the serving gNB of the RTT response signal; obtaining, by the serving gNB, a transmission time of the RTT response signal; receiving, at the serving gNB from the plurality of other nodes, information indicative of an RTT between the UE and each of the plurality of other nodes, wherein the information indicative of the RTT between the UE and each of the plurality of other nodes comprises information indicative of a transmission time of each of the plurality of the RTT measurement signals transmitted by the plurality of other nodes and of an arrival time of the RTT response signal at each of the plurality of other nodes; and enabling, by the serving gNB, determination of an RTT between the UE and the serving gNB and between the UE and each of the plurality of other nodes based on at least one of a transmission time at the serving gNB of the RTT measurement signal, the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals, the arrival time at the serving gNB of the RTT response signal, the transmission time of the RTT response signal, the information indicative of the RTT between the UE and each of the plurality of other nodes, and a timing adjust parameter for the UE. sending, by the serving gNB to the UE, a control signal indicating that the serving gNB and a plurality of other nodes will be transmitting a plurality of RTT measurement signals during a plurality of predefined symbols of downlink subframes, wherein the control signal further requests the UE to report the information indicative of an arrival time at the UE of each of the plurality of RTT measurement signals; sending, by the serving gNB to the UE, during one or more predefined symbols of a downlink subframe, an RTT measurement signal on a cell supported by the serving gNB, wherein the plurality of RTT measurement signals comprise the RTT measurement signal and the plurality of other RTT measurement signals transmitted by the plurality of other nodes; receiving, at the serving gNB from the UE, an RTT response signal, wherein the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals is included in a payload of the RTT response signal, and wherein reception of the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals comprises decoding the payload for the RTT response signal; obtaining, by the serving gNB, an arrival time at the serving gNB of the RTT response signal; obtaining, by the serving gNB, a transmission time of the RTT response signal; receiving, at the serving gNB from the plurality of other nodes, information indicative of an RTT between the UE and each of the plurality of other nodes, wherein the information indicative of the RTT between the UE and each of the plurality of other nodes comprises information indicative of a transmission time of each of the plurality of the RTT measurement signals transmitted by the plurality of other nodes and of an arrival time of the RTT response signal at each of the plurality of other nodes; and enabling, by the serving gNB, determination of an RTT between the UE and the serving gNB and between the UE and each of the plurality of other nodes based on at least one of a transmission time at the serving gNB of the RTT measurement signal, the information indicative of the arrival time at the UE of each of the plurality of RTT measurement signals, the arrival time at the serving gNB of the RTT response signal, the transmission time of the RTT response signal, the information indicative of the RTT between the UE and each of the plurality of other nodes, and a timing adjust parameter for the UE.
