Method and apparatus for decreasing multi-cell feedback overhead is provided in the present invention. Wherein a user equipment utilizes a first period to feedback short-term channel direction information of a serving base station, utilizes a second period to feedback long-term channel direction information of neighboring base stations, further, the user equipment utilizes a third period to feedback long-term relative amplitude information, utilizes a fourth period to feedback short-term relative phase information, wherein the first period is shorter than the second period, and the third period is longer than the fourth period. |
