PROBLEM TO BE SOLVED: To provide a radio frame control method capable of easily configuring a radio frame at a downward link of an OFDMA system, based on an IEEE 802.16 standard.SOLUTION: A radio frame configured from each resources of an OFDMA symbol and a subcarrier comprises a resources assignment 2. The resources assignment 2 makes the usage amount of resources of either the OFDMA symbol or the subcarrier constant, makes the usage amount of another resources variable, and then uses a resources assignment unit composed of a fixed amount of resources for the constant usage and a variable unit quantity of resources for the variable usage. The resources assignment 2 configures a data sequence from packets transmitted using a same modulation system and a same error correction encoding rate, and assigns the resources assignment unit to the data sequence.
