Abstract  Abstract

A method and apparatus for radio resources control in a multiple input multipleoutput (MIMO) orthogonal frequency division multiplexing (OFDM) communicationsystem are disclosed. Channel metric is calculated for each of a plurality oftransmit antennas. Sub-carriers are allocated to each transmit antenna in accordancewith the channel metric of each transmit antenna. Signals are transmitted usingthe allocated sub-carriers at each antenna. Adaptive modulation and codingand transmit power control of each sub-carrier may be further implemented inaccordance with the channel metric. Power control may be implemented per antennabasis or per sub-carrier basis. In performing power control a subset of transmitantennas may be selected and waterpouring may be applied only to the selectedantennas. Waterpouring may be based on SNR instead of channel response.
