Abstract: Overhead of signaling for retransmission control using a multiple codeword is decreased and throughput is improved. A radio communication apparatus performs data transmission by using the multiple codeword, and includes a reception device having a MIMO demodulation section 15 for demodulating data transmitted by the multiple codeword and an ACK/NACK generation section 21 for generating an ACK/NACK signal corresponding to the demodulation result of the demodulated data of respective codewords. The ACK/NACK generation section 21 allocates less resource to a signal corresponding to a low-order code word having a lower quality, and allocates more resource to a signal for a high-order codeword having a higher quality, thereby generating the ACK/NACK signal.

Abstract: A method for specifying a transport block-to-codeword mapping relationship and a method for transmitting a downlink signal using the same are described. If a swap flag has a first logic value, a first transport block is mapped to a first codeword and a second transport block is mapped to a second codeword. If the swap flag has a second logic value, the first transport block is mapped to the second codeword and the second transport block is mapped to the first codeword. If the size of any one of two transport blocks is 0, the swap flag is not used.

Abstract: A power controlling apparatus and method in a mobile communication system. A receiver in a mobile station multiplexes the frame reception result indicator bits for at least two traffic channels received from a transmitter in a base station, inserts the multiplexed frame reception result indicator bits in a pilot signal bit by bit, and transmits the reverse frame. Then, the transmitter extracts the pilot signal from the reverse frame, demultiplexes the frame reception result indicator bits, and performs a power control on the traffic channels based on the values of the frame reception result indicator bits.

Abstract: In a flexible layer one (403) of a GERAN transmitter device, a TFCI, which indicates a particular combination of cyclic redundancy check, channel coding and rate matching, is generated by a TFCI generating process (412) using information from the medium access control layer. The TFCI is coded by a coding process (413), and inserted into the data stream by a TFCI insertion process (414). Each code has more bits than the corresponding TFCI, and identifies uniquely the TFCI. The coded TFCI is spread across the pre-interleaved block with portions placed in fixed positions in each burst. Interleaving is then performed by an interleaver (411). The coded TFCI used with a half-rate channel is the central segment of the coded TFCI used in the corresponding full-rate channel. The additional loss is so small as to be insignificant, but the FER performance is significantly improved, compared to using the full-rate codes, as a result of the increased payload of the content data bits. In half-rate mode, the amount of coded TFCI data gives rise to a ratio of the performance of the coding of the transport format combination data to the performance of the coded content data which is at a similar level to the ratio in the full-rate mode.
