Patent ID: 8111621

Claim:
A communication method of a communication terminal used in a telecommunication system transmitting a transport channel composite having a plurality of transport channels between a base station and the communication terminal via a physical channel, performing rate matching process on data of each of said transport channels to change a transmission rate, and calculating a variation between a number of bits of each of said transport channels after the rate matching process and a number of bits of each of said transport channels before the rate matching process, the variation being used to perform rate matching process, the method comprising: first receiving step of receiving a first parameter controlling a rate matching ratio of each of said transport channels; second receiving step of receiving data of which the transmission rate is changed by the rate matching process via said physical channel, said physical channel having a maximum physical rate; and determining step of calculating a variation between a number of bits of each of said transport channels after the rate matching process and a number of bits of each of said transport channels before the rate matching process, based on first parameter received in the first receiving step and second parameter indicating said maximum physical rate corresponding to said transport channel composite, and third parameter indicating a maximum value of rate estimator corresponding to said transport channel composite.
