Abstract
The embodiment of the invention discloses a channel information obtaining method and device so as to obtain channel information between a terminal and network equipment. The method comprises the following steps: network equipment acquires channel information of N first channels, wherein the first channels are uplink channels between a first antenna port of terminal equipment and an nth antenna port of the network equipment; wherein n is equal to 1, 2,... N, and N is the number of antenna ports of the network equipment; the network equipment receives Q pieces of difference information sent by the terminal equipment; wherein each piece of difference information in the Q pieces of difference information is used for indicating difference information between channel information of a second channel and channel information of the first channel, and the second channel is an uplink channel between a second antenna port of the terminal device and an nth antenna port of the network device; wherein Q is a positive integer; and the network equipment determines uplink channel information between the terminal equipment and the network equipment according to the channel information of the N firstchannels and the Q pieces of difference information.
