Abstract:
1. A receiving apparatus in a communication system for encoding transmit data of a plurality of channels at respective ones of transmission time intervals (TTIs), partitioning the encoded data of each channel at a frame period to obtain frame data of prescribed bit lengths, transmitting and multiplexing the frame data of each channel, and transmitting, frame by frame, identification information (TFCI) that specifies frame-data length information (TFI) of the frame data on each channel, said apparatus comprising: a storage unit for storing multiplexed data that has been received; a discrimination unit for discriminating, frame by frame, frame-data length information (TFI) on each channel based upon the identification information (TFCI) that has been received; a decision unit for checking whether the frame-data length information (TFIs) of all frames within the transmission time interval (TTI) agree or not on a per-channel basis, and for deciding, when even one TFI differs, that the largest number of items of frame-data length information (TFI) that are the same among the items of frame-data length information in a plurality of frames within a transmission time interval (TTI) is frame-data length information common to all of said plurality of frames within the transmission time interval; a demultiplexer for identifying bit length per frame of each channel based upon the frame-data length information (TFI) that has been decided, and demultiplexing multiplexed data, which has been stored in the storage unit, channel by channel on the basis of the bit length; and a decoder for joining and decoding, in an amount equivalent to the transmission time interval, frame data that has been demultiplexed on a per-channel basis.
