摘要
A transmission apparatus and method updates a communication mode selection table that updates a communication mode selection table correctly and selects an optimal MCS according to an actual channel condition. A buffer temporarily stores calibration data to be transmitted for updating a table. A scheduler performs scheduling of data to be transmitted based on a CIR on a downlink reported from a plurality of communication terminal apparatuses. When there is no data to be transmitted, the scheduler sends calibration data from the buffer. When calibration data is transmitted as a result of the scheduling, the scheduler notifies an address information generation section of the communication terminal apparatus to which the calibration data is transmitted. In one mode, first data is transmitted from a first communication apparatus to another communication apparatus, the first communication apparatus receives from the other communication apparatus, information on an error rate when the other communication apparatus receives the first data; and;the first communication apparatus transmits second data to the other communication apparatus based on a communication mode determined using the information on the error rate.
