Abstract

A communication terminal apparatus that can perform an appropriate system operation at the network side and also can avoid a reduction in throughput and a reduction in system efficiency. In this apparatus, a compressed mode calculating part (124) determines, based on compressed information and slot format information, a slot that is a gap in a frame of a compressed mode. A transmission power control part (125) establishes a transmission power obtained by increasing, by Delta Pilot, the transmission power as designated and set by a TPC command for the slots other than the gap in the frame of the compressed mode. A DPCCH transmission power reporting part (127) outputs, to a channel encoding part (128), a report value indicative of the transmission power obtained by removing the effect of Delta Pilot from the transmission power established by the transmission power control part (125).

Description

technical field [0001] The present invention relates to a communication terminal device, a scheduling method, and a transmission power derivation method, and more particularly, to a communication terminal device, a scheduling method, and a transmission power derivation method on the network side that report the transmission power of a channel including known symbols to a base station or the like. Background technique [0002] Technology for high-speed transmission of packet data in the uplink is being researched and developed. In such a packet data transmission technique, it is necessary to allocate which communication terminal device to transmit, and this allocation, that is, scheduling is performed by the base station based on the transmission power of the channel transmitted by the relevant communication terminal or how much can be used in the transmission of packet data. Power information and the amount of transmission data that the communication terminal device has, etc...
