Abstract

A buffer 106 stores transmission data temporarily. A CQI transmission control section 113 outputs an instruction signal for generating CQI to a CQI generating section 107 when transmission data is accumulated in buffer 106 . CQI generating section 107 generates CQI based on quality information when the instruction signal is input from CQI transmission control section 113 , and does not generate CQI when the instruction signal is not input from CQI transmission control section 113 . A base station information extracting section 108 extracts transmit parameter information and scheduling information included in received data. A channel coding section 109 encodes transmission data based on encoding rate information in the transmit parameter information. A modulator 110 modulates the transmission data based on modulation scheme information in the transmit parameter information. By this means, a large volume of packet data can be communicated at high speed on the uplink in optimum conditions according to communication environment.

Description

technical field [0001] The present invention relates to a communication terminal device and a base station device, and more particularly to a communication terminal device and a base station device in a system performing high-speed packet transmission on an uplink, wherein the base station device performs scheduling. Background technique [0002] So far, HSDPA (High Speed ​​Downlink Packet Access) has been standardized in the field of wireless communication systems, in which many communication terminal devices share a high-speed and large-capacity downlink channel, and Perform high-speed packet transmission on the road. [0003] In this HSDPA system, in the period set by the base station equipment, the base station equipment instructs the communication terminal equipment to transmit a signal called CQI (Channel Quality Indicator) indicating the modulation scheme and coding rate of packet data, and The packet data can be demodulated in the terminal equipment. When the base...
