Patent ID: 8208363

Claim:
A transmitter, comprising: a resource block determination unit evaluating a channel condition for each of multiple resource blocks in each subframe and determining a resource block to be used by a communicating opponent based on the evaluation; a data modulation scheme and channel coding rate determination unit determining a data modulation scheme and a channel coding rate for the communicating opponent based on the evaluation; a control channel generation unit generating a control channel indicative of the resource block to be used by the communicating opponent, the data modulation scheme and the channel coding rate; a transmission unit transmitting data over a data channel together with control information over the control channel to the communicating opponent, the data channel being encoded at a channel coding rate determined by the data modulation scheme and channel coding rate determination unit and being modulated with a data modulation scheme determined by the data modulation scheme and channel coding rate determination unit; and a division unit dividing a data sequence to be transmitted into plural sequences, wherein the data modulation scheme and channel coding rate determination unit determining at least a modulation scheme for each of the plural divided sequences, wherein the respective determinations of the resource block, the data modulation scheme and the channel coding rate are made on a per-resource block basis, a per-transmission time interval basis or a per-packet basis, and wherein the division unit dividing the data sequence to be transmitted into a greater number of sequences than a number of transmission antennas.
