PROBLEM TO BE SOLVED: To provide a radio communication system and radio communication equipment in which efficiency in communications is improved by reducing pressure of communication channel capacitance due to an increase in communication information quantity. SOLUTION: In the radio communication system and the radio communication equipment, a data link part 103 generates a frame having common channel information to be transmitted-received by a common channel which is a common radio channel and individual channel information to be transmitted-received by an individual channel which is a radio channel different from the common channel and when transmitting the frame, a carrier is detected by a CPU 101 in the common channel. When the common channel is in an idle status as a result of carrier detection, data of the frame are modulated by a MODEM part 104 and transmitted from an RF part 105 via an antenna 13. Besides, the situation of using the individual channel is detected by an individual data carrier detection part 106 regardless of the transmission-reception of the frame, and an individual channel table is created/updated. Thus, a non-used individual channel is selectively used, so that a communication collision does not occur. COPYRIGHT: (C)2004,JPO
