A transmission method selection section (223) selects either a first packet transmission method or a second packet transmission method. When the first packet transmission method is selected, an SRQ information generation section (224) generates SRQ (scheduling request) information based on the amount of data calculated by a data amount measuring section (221) and/or the retention time thereof, and the transmission power that can be used for packet data transmission calculated by a transmission power calculation section (222). On the other hand, when the second packet transmission method is selected, the SRQ information generation section (224) does not perform SRQ information generation, or generates SRQ information of a specific value for which packet data transmission is never permitted. By this means, in a radio communication system in which packet transmission is performed on uplinks and the packet transmission method is switched adaptively, the packet transmission method can be reported without transmitting a dedicated signal to a base station apparatus.
A communication terminal apparatus used in a radio communication system in which packet transmission is performed in an uplink, and switching is performed adaptively between a first packet transmission method whereby a communication terminal apparatus performs packet transmission in accordance with base station apparatus scheduling and a second packet transmission method whereby a communication terminal apparatus performs packet transmission without a base station apparatus performing scheduling, said communication terminal apparatus comprising:
A base station apparatus used in a radio communication system in which packet transmission is performed in an uplink, and switching is performed adaptively between a first packet transmission method whereby a communication terminal apparatus performs packet transmission in accordance with base station apparatus scheduling and a second packet transmission method whereby a communication terminal apparatus performs packet transmission without a base station apparatus performing scheduling, said base station apparatus comprising:
A radio communication method used in a radio communication system in which packet transmission is performed in an uplink, and switching is performed adaptively between a first packet transmission method whereby a communication terminal apparatus performs packet transmission in accordance with base station apparatus scheduling and a second packet transmission method whereby a communication terminal apparatus performs packet transmission without a base station apparatus performing scheduling, wherein:
A communication terminal apparatus used in a radio communication system in which packet transmission is performed in an uplink, and switching is performed adaptively between a first packet transmission method whereby a communication terminal apparatus performs packet transmission in accordance with base station apparatus scheduling and a second packet transmission method whereby a communication terminal apparatus performs packet transmission without a base station apparatus performing scheduling, said communication terminal apparatus comprising:
