MODULATION CODING SCHEME SELECTION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A base station and method for selecting a modulation coding scheme (MCS) in an OFDM communication system, includes a first step 500 of estimating the channel response on each antenna based on the uplink feedback. A next step 502 includes calculating transmit weights from the uplink feedback. A next step 504 includes computing a beamformed Carrier-to-Interference plus Noise Ratio based on a broadcast Carrier-to-Interference plus Noise Ratio and the transmit weights and the channel response. A next step 506 includes choosing a best modulation coding scheme for a beamform allocation using the beamformed CINR. A best antenna gain and frequency band can also be chosen using the beamformed CINR.
