Abstract:
1. A method for a transmitter in a communication system, the method comprising: allocating first and second subchannels for signal transmissions to a receiver in the communication system, the subchannels containing Orthogonal Frequency Division Multiplexing (OFDM) subcarriers; transmitting, at a first transmission time, a first data packet over the first subchannel and a second data packet over the second subchannel; receiving a signal from the receiver indicating an error in the first data packet received by the receiver; and transmitting, at a second transmission time, a redundancy version of the first data packet over the second subchannel and a third data packet originally scheduled for the second subchannel over the first subchannel, wherein the first subchannel and second subchannels have different spatial configurations.
