Abstract
The present invention provides a TFCI decoding circuit and decoding method in which the TFI information for a relevant transport channel is determined, employing all the TFCI codeword information within the TTI, to enhance the receiving performance. A TTI combination pattern generating unit generates as a TTI combination pattern all the possible combinations of TFCI within a TTI having the longest interval among the TTIs for a plurality of transport channels, based on the fact that the TFI of a certain transport channel is not changed within the TTI on the transport channel. An adder adds, for each pattern, the likelihood for each radio frame calculated by a likelihood calculating unit, based on the TTI combination patterns. A TFI determination unit determines the TFI number of a relevant transport channel by selecting a pattern having the highest likelihood from among the TTI combination patterns.
