Abstract

The invention provides a channel state information measurement method and device. The channel state information measurement method comprises the steps that first equipment sends N reference signal ports to second equipment on a specified signal resource according to a specified sending mode, wherein the reference signal ports are used by the second equipment to measure channel state information between the first equipment and the second equipment, and N is a positive integer; and the first equipment receives the channel state information fed back by the second equipment. According to the invention, a problem of measurement for the channel state information in the related art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for measuring channel state information. Background technique [0002] The cellular network system in the related art mainly uses low frequency band (eg 300MHz-3GHz) frequency spectrum. However, with the increasing demands of communication services, the traditional low frequency band becomes more and more crowded, which is no longer enough to meet the needs of future communication. [0003] The characteristic of high-frequency communication is that it has relatively serious path loss and penetration loss, and its propagation in space is closely related to the atmosphere. Due to the extremely short wavelength of high-frequency signals, a large number of small antenna arrays can be applied to enable beamforming technology to obtain more accurate beam directions, and to improve the coverage of high-frequency signals with the advantages of narrow beam technology ...
