摘要： A radio channel control method for controlling, in a radio communication system having a transmitter and a receiver, a radio channel from the transmitter toward the receiver. The method includes receiving a signal transmitted from the transmitter by the receiver, measuring reception quality of the signal, generating information which indicates increment or decrement of the reception quality, and controlling a modulation or coding for the radio channel based on the information.

摘要： In a case where multiple kinds of frames having different lengths (Ngi_s and Ngi_l) of guard intervals inserted before the head of the effective data, the length of the guard intervals are adjusted in such a manner that at least the position of a part of the effective data is are apart from frame timing by the same amount. Thereby, on the receiving end, it is always possible to perform reception processing such as FFT processing in an appropriate time division at a fixed timing, without causing sample deviation of the effective data.

摘要： In a wireless communication system, a sender apparatus sends a data block, for each of a plurality of stream data, with data block identification information, which does not conflict between stream data, annexed, and a reception apparatus performs a re-sending synthesis process for a data block received already and a re-sending data block to which the same data block identification information is individually annexed based on the data block identification information annexed to the received data block. Consequently, also in a case wherein the number of transmission streams between the sender apparatus and the reception apparatus is varied (reduced), the matching property of the data block which is a re-sending synthesis target can be maintained and communication can be continued normally.
