Patent ID: 8638744

Claim:
A data transmission processing method, comprising: receiving, by a first base station, an adjustment parameter transmitted by a terminal, wherein the adjustment parameter is obtained by the terminal according to reference signals separately transmitted by the first base station and a second base station; performing, by the first base station and according to the adjustment parameter, channel compensation on a first channel between the first base station and the terminal to obtain a second channel; transmitting, by the first base station, a first signal over the second channel to the terminal, so that the terminal obtains the first signal from a mixed signal of the first signal and a second signal that is transmitted by the second base station, wherein the first signal and the second signal are transmitted by the first base station and the second base station using a same spectrum to the terminal, respectively; and wherein the adjustment parameter comprises A 1 and B 1 when the terminal has a single antenna, where A 1 comprises a difference between a phase of the first channel and a phase of a channel between the second base station and the terminal, and where B 1 comprises a ratio of a modulus of the channel between the second base station and the terminal and a modulus of the first channel.
