Abstract
The embodiment of the invention claims a channel information feedback method of antenna array comprising: the first network equipment receives the second network equipment transmits the N * M channel information of the sub-channel wherein the antenna array of the first network device includes M sub-array the second network device with the antenna array comprises N sub-arrays the first network device with the antenna array and the second network device with the antenna array channel comprises N* M sub-channels M and N are positive integers and are not 1 the same time M sub-array and N sub-array includes at least two antennas; according to the channel information of the channel from the second network device of N * M sub-channel of channel information to generate first network device of the antenna array with the second network device with the antenna array. Compared with the existing technology the embodiment of the invention of channel information feedback method in antenna array can reduce the complexity of the channel information and improve the efficiency of the channel information feedback.
Disclosed is a channel information feedback method for an array antenna comprising: a first network device receiving channel information about N x M sub-channels sent by a second network device wherein an array antenna of the first network device comprises M sub-arrays an array antenna of the second network device comprises N sub-arrays a channel between the array antenna of the first network device and the array antenna of the second network device comprises N x M sub-channels M and N are positive integers and are not one at the same time and the M sub-arrays and the N sub-arrays comprise at least two antennas; and according to the channel information about the N x M sub-channels from the second network device generating channel information about the channel between the array antenna of the first network device and the array antenna of the second network device. Compared with the prior art the channel information feedback method between array antennas disclosed in the embodiments of the present invention can reduce the complexity of acquiring channel information and improve the efficiency of channel information feedback.
