Document Type and Number:
WIPO Patent Application WO/2018/090812
Kind Code:
A1
Abstract:
Disclosed by the present invention are a method and apparatus in a user equipment (UE), a base station and a service center: A UE sends first information, then receives X1 first signals, and then sends a first measurement report. The first information is used to determine X1 first antenna ports, and the X1 first antenna ports are respectively used to send the X1 first signals; the first measurement report comprises K1 pieces of measurement information, and each of the K1 pieces of measurement information is for one of the X1 first signals; and the measurement information is used to determine at least the first two of a corresponding {time length set, first antenna port and first angle}. According to the present invention, the first information and the first measurement report are designed, and the feedback information selected by a beam is used for determining the generation and sending of a positioning reference signal under the condition of supporting a beamforming base station and UE, thereby improving the accuracy of UE positioning using the feature of strong directivity of beamforming.
