The invention discloses a method and a device for estimating the RF channel in a MIMO system parameters, so that the same site receives the matrix and the transmission matrix satisfies the transpose correspondence, simplified multiple input multiple output (MIMO) channel estimation information feedback multi antenna communication system. The technical solution includes: a base station control terminal to transmit uplink signals; the base station through the uplink signal estimation of uplink channel parameters: * up (k); the base station control terminal measurement of downlink channel parameters: * down (k); terminal through downlink signal estimation in downlink channel parameters: down * (k); downlink channel parameter estimation: terminal * down (k) reported to the base station; the base station through the following equation is transformed into linear form solution of equation, to obtain the A matrix: AP (k) and A: UE (k), the equation is: down * A = \1: AP: a case of UE * = T: up = 0, A: AP (k) said the base station receives the radio frequency and transmission RF link response ratio, A: UE (k) that the mobile station receiving and sending radio frequency RF link response ratio. The invention is applied to the field of mobile communication.
