Abstract

The present invention provides a channel measurement feedback method and device, and a pilot transmission method and device, wherein the method includes: determining the detection parameters of the first type of channel state information CSI measurement reference information, wherein the first type of CSI measurement reference information It is at least one of the following: control information demodulation reference pilot signal, data information demodulation reference pilot signal; detect the first type of CSI measurement reference information according to the detection parameters; when the first type of CSI measurement reference information is detected, Performing CSI measurement based on the first type of CSI measurement reference information to obtain the first type of CSI measurement result; feeding back the first type of CSI measurement result to the sending end. The present invention solves the problem in the related art that the efficiency of beam training is not high due to the need for a large amount of measurement beam pilot overhead, and achieves the effect of improving the efficiency of beam training.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a channel measurement feedback method and device, and a pilot frequency sending method and device. Background technique [0002] In wireless communication systems, as the number of antennas increases, beamforming technology is used to enhance the coverage of various channel signals, especially in high-frequency systems, due to the relatively large path loss, Therefore, it is generally necessary to adopt the beamforming technology to ensure the basic coverage requirements of various channels. [0003] Beamforming such as figure 1 As shown in the figure, it includes: baseband precoding beamforming and radio frequency precoding beamforming. Baseband precoding mainly refers to the precoding acting on the radio frequency path, and radio frequency precoding mainly refers to the effect on the radio frequency path. Precoding, the former is done on the baseband and the latter ...
