Method and Device for User Equipment Positioning

A method for positioning by a central device of a radio access network (RAN) node, comprising:

• receiving, by the central device, positioning measurement request information from a location management function (LMF) device, wherein the RAN node comprises the central device and at least two distributed devices;
• sending, by the central device, uplink signal configuration information to a first distributed device and a second distributed device of the at least two distributed devices, wherein the uplink signal configuration information is sent to a first distributed device through a first application protocol signaling and the uplink signal configuration information is sent to a second distributed device through a second application protocol signaling;
• receiving, by the central device, a positioning measurement report comprising a first uplink signal measurement report from the first distributed device though a third application protocol signaling and a second uplink signal measurement report from the second distributed device through a fourth application protocol signaling;
• and
• sending, by the central device, the positioning measurement report to the LMF device.

A central device of a radio access network (RAN) node, comprising:

• one or more processors, and
• a non-transitory computer-readable medium coupled to the one or more processors and storing computer instructions that when executed by the one or more processors, cause the one or more processors to:
• receive positioning measurement request information from a location management function (LMF) device, wherein the RAN node comprises the central device and at least two distributed devices;
• send uplink signal configuration information to a first distributed device and a second distributed device of the at least two distributed devices, wherein the uplink signal configuration information is sent to a first distributed device through a first application protocol signaling and the uplink signal configuration information is sent to a second distributed device through a second application protocol signaling;
• receive a positioning measurement report comprising a first uplink signal measurement report from the first distributed device though a third application protocol signaling and a second uplink signal measurement report from the second distributed device through a fourth application protocol signaling;
• and
• send the positioning measurement report to the LMF device.
