Abstract
A radio transmitting device and method enables reduction of an increase of CGI memories for the control channel and an improvement of the throughput of the data channel. When multiplex transmission through the control channel and the data channel is carried out and when adaptive modulation is applied to both channels, an MCS selecting section (108) is provided with one CQI table for the data channel and CQI tables for the control channel, and a table selecting MCS determining section (201) selects one of the tables depending on the transmission bandwidth of the terminal and determines the MCS of the control channel while looking up the selected CQI table.
Claims14
A radio transmission apparatus comprising:
- a coding unit configured to code one form of control data using a modulation and coding scheme (MCS) for a data channel and an offset value, the offset value being set for said one form of the control data;
- and
- a radio transmitting unit configured to transmit data in the data channel and said one form of the control data coded with a coding rate according to said one form of the control data.
A radio transmission method comprising:
- coding one form of control data using a modulation and coding scheme (MCS) for a radio data channel and an offset value, the offset value being set for said one form of the control data;
- and
- transmitting data in the radio data channel and said one form of the control data coded with a coding rate according to said one form of the control data.
