METHOD FOR FEEDBACK AND METHOD FOR CONFIGURING A CODEBOOK IN MULTI-ANTENNA SYSTEM
摘要
<p>A feedback method for a multi-antenna system is disclosed. The feedback method for use in the multi-antenna system can reduce an amount of transmission (Tx) feedback information associated with a precoding matrix (i.e., a codebook). For example, a single codebook may include precoding matrixes associated with several ranks. A basic matrix constructing the precoding matrix is extended to a frequency axis, such that it can be used as a Cyclic Delay Diversity (CDD) structure.</p>
