Patent ID: 8149727

Claim:
A transmitting method for use by a transmitting apparatus for transmitting data and control information in a single carrier system, the method comprising: determining a modulation and coding scheme (MCS) for the data based on information for determining the MCS, the information for determining the MCS being transmitted from a base station; calculating a coding rate for the control information based on the information for determining the MCS and offset information transmitted from the base station, the coding rate being calculated according to arranged information that defines a relationship among a coding rate portion of the MCS, the offset information, and the coding rate, the arranged information being contained in the transmitting apparatus, wherein a value of the offset information is used to adjust the coding rate portion of the MCS; transmitting the data using the MCS; and transmitting the control information using the coding rate, wherein a total bit length of the offset information is smaller than a total bit length of the information for determining the MCS.
