ABSTRACT:
A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S) of spatial multiplexed symbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.
