Abstract
A method is provided for scheduling data transmission in a Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) system. The MIMO-OFDM system may comprise at least one MIMO-OFDM transmitter and at least one MIMO-OFDM receiver. Feedback from one or more receivers may be used by a transmitter to improve quality capacity and scheduling in MIMO-OFDM communication systems. The method may comprise generating or receiving information pertaining to a MIMO channel metric and information pertaining to a Channel Quality Indicator (CQI) in respect of a transmitted signal; and sending a next transmission to a receiver using a MIMO mode selected in accordance with the information pertaining to the MIMO channel metric and an adaptive coding and modulation selected in accordance with the information pertaining to the CQI.
