REALLOCATION OF EXCESS POWER FOR FULL CHANNEL-STATE INFORMATION (CSI) MULTIPLE-INPUT, MULTIPLE-OUTPUT (MIMO) SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a method of reallocating excess power for full channel-state information (CSI) multiple-input, multiple-output (MIMO) systems.SOLUTION: The total transmit power may be initially allocated to transmission channels on the basis of a particular power allocation scheme 214. The initial allocation may result in more power being allocated to some transmission channels than needed to achieve a required SNR 220. In such situations, the present techniques reallocate excess transmit power of transmission channels operated in a saturation region to other transmission channels operated in or below the saturation region 226.
