Abstract: PROBLEM TO BE SOLVED: To provide a communication system, especially, radio communication system to use the strongest coding/modulating system to the quantity of applied payload bits. SOLUTION: Concerning this system, the quantity of payload bits applied in channel quality index (CQM) and block is considered. A transmitter uses one of (k) kinds of coding/modulating systems in the case of transmitting data on a radio data network. First of all, the transmitter selects a coding/modulating system C, for example, as a C/I measuring function (215). Continuously, the transmitter calculates the number B of blocks required for transmitting a data packet group D while using the coding/modulating system C (220). Besides, the transmitter calculates the number of blocks required for transmitting the data packet group D to each coding/modulating system stronger than the selected coding/modulating system C.
