SU-BF MU-MIMO METHOD AND SYSTEM FOR UNIFIED RATE ADAPTATION FOR SU-BF AND MU-MIMO OPERATION

摘要

A method for providing rate adaptation in a multi-user wireless communication system including single-user beamforming (SU-BF) and multi-user multi-input multiple-output (MU-MIMO) is described. In this method, the master rate, which is the modulation and coding scheme (MCS) for SU-BF, is determined. The MCS for each transmission mode is derived from the master rate using rate mapping. Using the results from the mapping, the master rate is tracked instead of the MCS for each transmission mode. In one embodiment, mapping correction is performed periodically.
