Abstract  Abstract

Embodiments of the present invention disclose a method of feeding back information regarding channels between antenna arrays. The method includes the step of the first network device receiving channel information of N × M subchannels transmitted by the second network device, wherein the antenna array of the first network device is M pieces. And the antenna array of the second network device includes N subarrays, and the channel between the antenna array of the first network device and the antenna array of the second network device has N × M subarrays. Including channels, M and N are positive integers and both are not 1, M subarrays and N subarrays each include at least two antennas, and N from the second network device The antenna array of the first network device and the second network device according to the channel information of × M subchannels Of and generating channel information of a channel between the antenna array. Compared with the prior art, embodiments of the present invention can reduce the complexity of acquiring channel information and improve the efficiency of channel information feedback by the disclosed method of feeding back information about channels between antenna arrays. it can.
