Method and apparatus for adjusting a data transmission rate

The present invention discloses a method and apparatus for adjusting a data transmission rate, wherein the method comprises adjusting the period of the data transmission rate, the sender information to determine trends in data transmission rate according to channel state, data transmission rate is determined based on the trends data transmission mode and a modulation and coding scheme, the transmit end using the determined data transmission mode and the transmission data modulation and coding scheme. According to the present invention, to solve the problem of data transmission rate and channel condition mismatch, increased stability and increased link system throughput.
