Abstract

The embodiment of the application discloses a channel information feedback method of an antenna array. The channel information feedback method of the antenna array comprises the following steps: a first network device receives the channel information of NxM sub-channels sent by a second network device, wherein the antenna array of the first network device comprises M sub-arrays, the antenna arrayof the second network device comprises N sub-arrays, the channel between the antenna array of the first network device and the antenna array of the second network device comprises NxM sub-channels, Mand N are positive integers and are not both 1 at the same time, and the M sub-arrays and the N sub-arrays comprise at least two antennas; and the channel information between the antenna array of thefirst network device and the antenna array of the second network device is generated according to the channel information of the NxM sub-channels from the second network device. Compared with the prior art, the channel information feedback method between antenna arrays disclosed by the embodiment of the application can reduce the complexity of obtaining the channel information and improve the efficiency of channel information feedback.
