| 摘要 |
A method (500) for wireless communications is described, the method comprising receiving (502) multiple feedback aspects of a channel for the wireless communications, determining (504) multiple codewords (W 1 , W 2 ) based on the multiple feedback aspects, determining (506) a final precoding matrix (W) based on the multiple codewords (W 1 , W 2 ), enforcing (508) at least one codebook property in at least one of the final precoding matrix (W) or the multiple codewords (W 1 , W 2 ), wherein enforcing the at least one codebook property comprises quantizing each of the multiple codewords (W 1 , W 2 ) or quantizing the final precoding matrix (W), applying (510) the final precoding matrix (W) to a plurality of spatial streams to form precoded spatial streams and transmitting (512) the precoded spatial streams. Also the corresponding apparatus is described. |
