Patent ID: 7274681

Claim:
A method of multiplexing information for mobile communications in which a plurality of pieces of information are multiplexed into a same radio frame and multiplex-transported over a radio circuit, said plurality of pieces of information having each Transmission Time Intervals selected from a plurality of types and said Transmission Time Intervals being the shortest time lengths during which data may be decoded, wherein a Transport Format Combination Indicator indicating a combination of number of data within said Transmission Time Interval of each of said plurality of pieces of information is inserted into each radio frame and transported, the method comprising: selecting and transporting said Transport Format Combination Indicator such that a high-order bit of said transport Format Combination Indicator can be changed when there is change in the number of data within said Transmission Time Interval with respect to information having a longest Transmission Time Interval; wherein said Transport Format Combination Indicator is encoded by using a coefficient including a mask code and is inserted into each radio frame, and when a value taken by said Transport Format Combination Indicator corresponds to a value represented by including a bit corresponding to a portion of said mask code and when the number of data within said Transmission Time Interval with respect to information having a longest Transmission Time Interval is determined, said Transport Format Combination Indicator is selected and transported such that a bit corresponding to the part of said mask code of said Transport Format Combination Indicator is determined.
