Abstract

The invention discloses an acquiring method and a device of channel condition information. The problem that a feedback mechanism is not flexible when a customer satisfaction index (CSI) of a wireless channel between different transmission points and user equipment is acquired is solved. The acquiring method comprises that first the user equipment receives at least two channel condition information CSI measurement reference resource collections sent by a base station; then, according to each CSI measurement reference collection of the at least two channel condition information CSI measurement reference resource collections, the user equipment respectively measures the CSI between the transmission points or/and transmission point combinations corresponding to each CSI measurement reference resource collection and the user equipment, and acquiring the feedback mechanisms which can satisfy the CSI demands between the transmission points or/and the transmission point combinations and the user equipment; and at last, the user equipment feeds back measurement results to the base station through the same or different feedback mechanisms. The acquiring method and the device of the channel condition information are suitable for 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 points 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" below 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 Signal ...
