Abstract:
A method of wireless communication is disclosed which includes acquiring a first set of precoding matrices for a set of frequency bands and generating a second set of precoding matrices for the set of frequency bands based on the first set of precoding matrices. The second set of precoding matrices enables a transmission that satisfies a cubic metric criteria in multiple-in multiple-out communication mode in the uplink. In some designs, generating the second set of precoding matrices can be based on restricting the first set of precoding matrices for a set of frequency bands and transmission rank, rotating the first set of precoding matrices based for a predetermined transmission rank, or a combination thereof.
