Patent ID: 7339998

Claim:
A method of selecting transport format combination information in a communication apparatus for selecting prescribed transport format combination information from a plurality of items of transport format formation combination information TFCj (j=1, 2, . . . ) that stipulates a combination of transmission format indicators (TFIs) each of which specifies transport data bit length of a prescribed transmission time interval (TTI) of a transport channel, multiplexing transport data of each of the transport channels based upon the transport format combination information that has been selected, and transmitting this data, said method comprising the steps of: classifying each transport format combination information TFCj (j=1, 2, . . . ) to plural classes based upon amount of multiplexed transport data of each transport channel; measuring a transmission power of the communication apparatus; deciding a class of transport format combination information to be selected, so that said transmission power of the communication apparatus does not become larger than a designated maximum transmission power; and selecting transport format combination information from the class that has been decided, based upon an actual transport bit rate of each transport channel.
