Abstract: PURPOSE: A method for reducing resource allocation overhead to be used inside a radio communication system is provided to enable efficient operation of channel resources by excluding the non-efficient utilization of the channel resources by autonomously reporting system data from a remote site and allocating a transmission parameter through a local controller while using this information. CONSTITUTION: A remote site of mobile equipment(106) autonomously supplies the system data such as the measured value of a received signal strength, for example, through a base station transceiver(104) to a base station controller(102) during a period in which a communication link is settled active. Thus, the reduction of setting overhead is achieved. By using the autonomous report of the measured reception strength, the base station controller(102) can control burst transmission parameter allocated before each of burst transmission such as data velocity, band width and nominal initial output power, for example. Further, based on this autonomous report of the received signal strength, in the case of burst transmission, the base station controller(102) can control energy from the base station controller(102).
