Abstract:
1. A wireless communication system comprising: a transmitting device that transmits data in frame units that are modulated based on MCS (Modulation and Coding Scheme) determined by adaptive modulation and an MCS identifier that specifies MCS; and a receiving device, which is configured to conduct wireless communication with the transmitting device, and demodulate received data based on MCS specified by the received MCS identifier; wherein the transmitting device comprises wherein the receiving device comprises, wherein the data modulating unit modulates the error part of the data maintained in the transmission data maintaining unit and specified by the frame identifier and the identifier of the error part in the ARQ based on the MCS maintained in the transmission data maintaining unit, after a predetermined frame from receiving the ARQ; wherein the data transmitting unit retransmits the modulated data; wherein the data demodulating unit demodulates an error part of the received data based on the MCS maintained in the demodulated data maintaining unit; and wherein the receiving device further comprises a chase combining unit for chase combining the demodulated error part and the data maintained in the demodulated data maintaining unit.
