Abstract

The embodiment of the present invention discloses a method and device for acquiring channel state information, which solves the problem of inflexible feedback mechanism when acquiring CSI of wireless channels between different transmission points and user equipment. The method includes: first, the user equipment receives at least two channel state information CSI measurement reference resource sets sent by the base station; then the user equipment receives each CSI measurement reference in the at least two channel state information CSI measurement reference resource sets set, respectively measure the CSI between the transmission point or / and transmission point combination corresponding to each CSI measurement reference resource set and the user equipment, and obtain and satisfy the transmission point or / and transmission point combination and the A feedback mechanism of the CSI requirements between the user equipments; finally, the user equipment feeds back the measurement results to the base station through the same or different feedback mechanisms. The invention is applicable to the field of communication systems.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a method and device for acquiring channel state information. Background technique [0002] In traditional wireless communication systems, each user equipment (User Equipment, UE) usually only receives data and signaling information sent from one cell, where each cell contains one or more transmission points with transceiver devices, one with transceiver The transmission point of the device may correspond to one or more antennas. A skilled person can easily understand that the "cell" or "the transmission point corresponding to the cell" hereinafter have the same meaning. [0003] Usually, in order for the base station to perform reasonable scheduling, the base station needs to know the channel state information (Channel State Information, CSI) of the wireless channel between the transmission point and the UE, which is often sent by the UE to the reference signal (Reference Si...
