Disclosed is a communication system in which appropriate retransmission control operations are respectively performed for two data types including real time data and non real time data, and the transmitter and the receiver used for this communication system. A data type identifier (240) identifies a data type as real time or non real time, and based on the identified data type, a controller (210) and another controller adjust parameters used for retransmission control.
