Apparatus for determining a coding rate

Abstract

A radio transmitting apparatus determines a first coding rate for transmitting, in a single carrier system, data information based on information for determining the first coding rate, the information for determining the first coding rate being received from a base station; and determines a transmission power for the data information and the control information based on the information for determining the first coding rate.

         8 . The radio transmitting apparatus of  claim 1 , further comprising a transmitter configured to transmit the data information and the control information. 
     
     
         9 . The radio transmitting apparatus of  claim 1 , wherein the information for determining the first coding rate comprises a channel quality indicator (CQI). 
     
     
         10 . The radio transmitting apparatus of  claim 1 , wherein the software program code when executed causes the processor to perform the further act of selectively performing transmission power control on the data information and the control information. 
     
     
         11 .

         12 . The radio transmitting apparatus of  claim 10 , wherein the software program code when executed causes the processor to perform the further act of selectively performing transmission power control on the data information and the control information. 
     
     
         13 . A method of operating a radio transmitting apparatus comprising:
 determining a first coding rate for transmitting, in a single carrier system, data information based on information for determining the first coding rate, the information for determining the first coding rate being received from a base station; and   determining a transmission power for the data information and the control information based on the information for determining the first coding rate; and   transmitting the data information and the control information.   
     
     
         14 . The method of  claim 13 , wherein the information for determining the first coding rate comprises modulation and coding scheme (MCS) information received from a base station.
