WIPO Patent Application WO/2016/134537
Kind Code:
A1
Abstract:
Disclosed are a channel quality measurement method, apparatus and system. The method comprises: a first user equipment receives a first-type reference signal and at least one second-type reference signal sent by a first base station, the first-type reference signal being configured with reference signal resources of M antenna ports, and the second-type reference signal being configured with reference signal resources of N antenna ports; the first user equipment measures channel quality based on the first-type reference signal to obtain a first measurement result; the first user equipment measures channel quality based on the at least one second-type reference signal to obtain a second measurement result; and the first user equipment sends the first measurement result and the second measurement result to the first base station. By means of the present invention, a downtilt angle of a vertical beam of a cell configured with an AAS can be adjusted according to channel quality measurement results corresponding to reference signals having different configurations.
