摘要： An embodiment of the present application relates to the technical field of wireless communications, in particular to a positioning information determination method and device, for solving the problem of large positioning result errors in the prior art due to the fact that existing positioning methods cannot acquire the height difference between a UE and a base station. The positioning information determination method provided in the embodiment of the present invention comprises: a base station receives an uplink signal from a UE; and the base station determines the angle of arrival, beam declination angle and timing advance of the UE according to the received uplink signal. By determining the angle of arrival, beam declination angle and timing advance of a UE according to the received uplink signal, the base station determines the height difference between the UE and the base station according to the beam declination angle, thus reducing positioning result error and improving positioning precision.

摘要： The embodiments of the disclosure relate to the technical field of wireless communications, and particularly relate to a method, a system and a device for feeding back and receiving a Pre-coding Matrix Indicator (PMI), which is used for feeding back a vertical dimension PMI. The method for feeding back the PMI provided by the embodiments of the disclosure comprises: confirming the PMI needed to be fed back, wherein the PMI comprises a horizontal dimension PMI and a vertical dimension PMI, or a PMI combined by horizontal dimension and vertical dimension (801); feeding back the confirmed PMI in a non periodic Channel State Information (CSI) feedback mode or a periodic CSI feedback mode (802). Since the capability of feeding back the vertical dimension PMI, dynamic 3D beam shaping technology can be implemented and the throughput of the user equipments in the edge of cell and the average throughput can be improved.
