Realizing method, dividing method and multiplexing method of feedback channel

The invention discloses a realizing method, a dividing method and a multiplexing method of a feedback channel. The realizing method of the feedback channel comprises the following steps: dividing an uplink HARQ feedback area into HARQ feedback channel transmission resource blocks with the number of N according to a predetermined rule, wherein the uplink HARQ feedback area consists of M logic resource blocks, wherein both N and M are natural number; and each HARQ feedback transmission resource block multiplexes HARQ feedback channels with the number of R in the form of orthogonal code, wherein R is a natural number. By adopting the technical scheme, the uplink chain channel resource can be efficiently utilized, and the transmission performance of feedback information is ensured.
