In an embodiment, a central device of a radio access network (RAN) node, which comprises the central device and at least two distributed devices, receives positioning measurement request information from a location management function (LMF) device. The central device separately sends uplink signal configuration information to a first distributed device and a second distributed device of the at least two distributed devices in application protocol signaling The first and two distributed devices measure an uplink signal sent from a user equipment, and the two distributed devices separately sends a uplink signal measurement result in an application protocol signaling to the central device. The central device sends a positioning measurement result comprising the two uplink signal measurement results to the LMF device. ## Claims ### Claim 1 A method, comprising: receiving, by a first distributed device of a radio access network (RAN) node from a central device of the RAN node, first uplink signal configuration information;
