Title:
RADIO COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/001357
Kind Code:
A1
Abstract:
[PROBLEMS] To improve the throughput and reduce the circuit size and power consumption for transmission. [MEANS FOR SOLVING PROBLEMS] A radio communication device performs radio communication by the multi-carrier transmission method using a frame composed of a plurality of sub-frames. The radio communication system includes: an extraction unit (8) for extracting a modulation parameter from a modulation information sub-frame constituting the received frame and reporting the modulation parameter of each sub-carrier to the reception side; a storage unit (9) for storing a modulation parameter extracted; and a modulation control unit (10) used when transmitting a frame to a frame transmission source, for encoding the transmission data or modulating each sub-carrier by using the modulation parameter stored. The radio communication device transmits a frame containing no modulation information sub-frame to the frame transmission source.
