Mobile wireless communication system and wireless communication apparatus

Abstract

A mobile wireless communication system including a wireless communication apparatus and a counterpart wireless communication apparatus is provided, the system establishing wireless communication between the wireless communication apparatus and the counterpart wireless communication apparatus by multiplexing plural channels including at least a traffic channel for transmitting a packet, a control channel for transmitting control information for receiving the packet, and a channel for transmitting information including transmission power control information. The wireless communication apparatus includes a transmission unit that transmits the transmission control information to the counterpart wireless communication apparatus via the channel for transmitting information including transmission power control information at intervals of a prescribed period that is longer than a length of the packet, and transmits the transmission power control information via the control channel when the packet is being transmitted via the traffic channel.

What is claimed is: 
     
         1 . A method for mobile wireless communication system including a base station and a mobile station, the method comprising:
 multiplexing by the base station a plurality of channels including a first channel for transmitting data, a second channel for transmitting control information including modulation scheme information, redundancy version information, retransmission control information, and a new data indicator for transmitting data using the first channel, a first power control information, and a third channel for transmitting information including a second power information;   transmitting the plurality of channels from the base station to the mobile station; and   receiving the plurality of channels by the mobile station.   
     
     
         2 . The method for mobile wireless communication according to  claim 1 , wherein a first power level represented by the first power control information is arranged to be greater than or equal to a second power level represented by the second power control information.
