A method of coordinating multi-cell round trip time, RTT, positioning signaling, the method performed by a server comprising a location management function, and the method comprising: identifying a first user equipment, UE, served by a base station and a second UE served by the base station, the base station being configured to send a base station downlink, DL, positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for the first UE to send first UE uplink, UL, positioning signals, and second times to the second UE, for the second UE to send second UE UL positioning signals, at least one of the first times being different from at least one of the second times, wherein the first times are allocated to be proximate in time to a first plurality of the plurality of base-station-transmission times and the second times are allocated to be proximate in time to a second plurality of the plurality of base-station-transmission times, the first plurality different from the second plurality, at least one instance of the first UE UL positioning signal configured to form a first RTT pair with a respective first instance of the base station DL positioning signal transmitted at a first time of the plurality of base-station transmission times, at least one instance of the second UE UL positioning signal configured to form a second RTT pair with a different respective instance of the base station DL positioning signal transmitted at a second time of the plurality of base-station transmission times; sending a first communication to cause the first UE to send at least a respective one of the first UE UL positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE UL positioning signals at each of the second times. identifying a first user equipment, UE, served by a base station and a second UE served by the base station, the base station being configured to send a base station downlink, DL, positioning signal wirelessly at a plurality of base-station-transmission times; allocating first times to the first UE, for the first UE to send first UE uplink, UL, positioning signals, and second times to the second UE, for the second UE to send second UE UL positioning signals, at least one of the first times being different from at least one of the second times, wherein the first times are allocated to be proximate in time to a first plurality of the plurality of base-station-transmission times and the second times are allocated to be proximate in time to a second plurality of the plurality of base-station-transmission times, the first plurality different from the second plurality, at least one instance of the first UE UL positioning signal configured to form a first RTT pair with a respective first instance of the base station DL positioning signal transmitted at a first time of the plurality of base-station transmission times, at least one instance of the second UE UL positioning signal configured to form a second RTT pair with a different respective instance of the base station DL positioning signal transmitted at a second time of the plurality of base-station transmission times; sending a first communication to cause the first UE to send at least a respective one of the first UE UL positioning signals at each of the first times; and sending a second communication to cause the second UE to send at least a respective one of the second UE UL positioning signals at each of the second times.
