Abstract
In a radio communication system, communication for sending data from a transmitting station to a receiving station and communication for transmitting re-send data from the transmitting station to the receiving station according to the re-send request transmitted from the receiving station to the transmitting station are done on different occasions of communication. Hence, in the applications not requiring real time service, this re-send control method does not spend the power and radio resources wastefully, and by effectively utilizing the system resources and lowering the power consumption, the battery of the terminal may be reduced in size, so that the portability of the terminal may be enhanced. Further, the radio communication system has a high speed down-link channel and a low speed down-link channel, data to be transmitted from a base station to a terminal is classified into primary data and secondary data, the primary data is transmitted by the high speed down-link channel, and the secondary data is transmitted by the low speed down-link channel.
