Abstract
A method and apparatus for radio resources control in a multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) communication system are disclosed. Radio resources are controlled by producing and applying a respective adaptive modulation and coding to each data stream. Applying a respective transmit power level to that data stream and mapping that data stream to a plurality of antennas. Each of the plurality of data streams are transmitted over different subcarriers, has a different adaptive modulation and coding (AM&C) and a different transmit power than others of the plurality of data streams.
Claims6
A wireless transmit/receive unit (WTRU) comprising:
- circuitry configured to produce a plurality of data streams;
- the circuitry is further configured for each of the plurality of data streams:
- to apply a respective adaptive modulation and coding to that data stream, apply a respective transmit power level to that data stream and map that data stream to a plurality of antennas;
- wherein each of the plurality of data streams are transmitted over different subcarriers.
A method comprising:
- producing, by a wireless transmit/receive unit (WTRU), a plurality of data streams;
- for each of the plurality of data streams:
- applying, by the WTRU, a respective adaptive modulation and coding to that data stream;
- applying, by the WTRU, a respective transmit power level to that data stream;
- and
- mapping, by the WTRU, that data stream to a plurality of antennas;
- wherein each of the plurality of data streams are transmitted over different subcarriers.
