Patent ID: 8526319

Claim:
A method for wireless communication, comprising: determining at least one parameter based on at least one constellation constrained capacity function; and determining channel quantity indicators (CQIs) for multiple streams for a non-linear detector based on the at least one parameter, wherein the multiple streams comprise a first stream and a second stream, wherein the determining the at least one parameter comprises determining at least one first threshold for the first stream and at least one second threshold for the second stream based on the at least one constellation constrained capacity function, each first threshold corresponding to a different modulation order for the second stream, and each second threshold corresponding to a different modulation order for the first stream, wherein the determining the at least one first threshold and the at least one second threshold comprises determining the at least one first threshold and the at least one second threshold based further on a precoding matrix and a channel matrix, and wherein the determining the CQIs for the multiple streams comprises evaluating each of a plurality of precoding matrices, selecting a precoding matrix associated with a highest overall throughput among the plurality of precoding matrices, and determining CQIs for the first and second streams based on a first threshold and a second threshold corresponding to the highest overall throughput for the selected precoding matrix.
