<p>A method for reference signal transmission, a method for channel quality estimation, a mobile station, a base station, and a wireless communication system are disclosed in the present invention. A method doe reference signal transmission includes: according to a first precoding matrix for precoding data sent by multiple antennas of a mobile station, precoding a demodulation reference signal sent with the data; according to a second precoding matix, precoding a sounding reference signal sent with the data, wherein the different columns and the different rows of the first precoding matrix and the second precoding matix correspond to different data and different antennas respectively; transmitting the precoded sounding reference signal and the precoded demodulation reference signal, wherein the ranks of a matrix composed by arrangement of the whole column vectors of the first precoding matrix and the whole column vectors of the second precoding matrix are greater than or equal with the number of antennas. Under the circumstance of the mobile station equipped with multiple antennas, the present invention can effectively reduce the occupation of Sounding Reference Signal (SRS) resource during the each antenna channel quality estimation.</p> |
