<p>Disclosed are a method, device and MIMO system for acquiring a main-secondary stream channel reference offset and a secondary stream block length, which relate to the field of communications. By setting 0 dB to be the largest main-secondary stream channel offset value, and -31 dB—-12 dB to be the value range of the smallest main-secondary stream channel offset value, an offset between two neighbouring main-secondary stream channel offset values is able to be smaller than or equal to 1 dB, i.e. the linear value grain of a secondary stream channel offset value is able to be finer, thus the obtained secondary stream block length is more precise. The method employed in the embodiments of the present invention is: the main-secondary stream channel reference offset consists of 30-32 main-secondary stream channel reference offset values and index values corresponding to the main-secondary stream channel offset values one by one, wherein the main-secondary stream channel offset values are in a linear distribution, and the largest main-secondary stream channel offset value is 0 dB, and the value range of the smallest main-secondary stream channel offset value is -31 dB—-12 dB.</p> |
