Abstract

The invention provides a channel measurement feedback method and device as well as a pilot transmission method and device. The channel measurement feedback method comprises the following steps: determining detection parameters of first type channel state information (CSI) measurement reference information, wherein the first type CSI measurement reference information is at least one of a control information demodulation reference pilot signal and a data information demodulation reference pilot signal; detecting the first type CSI measurement reference information according to the detection parameters; under the situation that the first type CSI measurement reference information is detected, performing CSI measurement based on the first type CSI measurement reference information to obtain afirst type CSI measurement result; and feeding back the first type CSI measurement result to a transmitting end. Through adoption of the channel measurement feedback method and device as well as the pilot transmission method and device, the problem that beam training efficiency is not high due to the need of a large amount of measurement beam pilot overhead in the prior art is solved, and the effect of increasing the beam training efficiency is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a channel measurement feedback method and device, and a pilot transmission method and device. Background technique [0002] In wireless communication systems, as the number of antennas increases, it is a trend to use Beamforming (beamforming) technology 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 Beamforming technology to ensure the basic coverage requirements of various channels. [0003] Beamforming such as figure 1 As shown, it includes two parts: baseband precoding beamforming and RF precoding beamforming. Baseband precoding mainly refers to the precoding acting on the radio frequency path, and radio frequency precoding mainly refers to the Precoding, the former is done on the baseband, and the latter is done on the radio frequency. [0004] ...
