摘要： Disclosed is a transmission device which transmits a systematic code obtained by adding parity bits to information bits. When the code rate of the systematic code is a value in a specific range determined by the decoding characteristic in a case where dummy bits are not inserted, a dummy bit insertion portion inserts dummy bits into the information bits and shifts the decoding characteristic, so that the code rate assumes a value outside a specific range determined by the decoding characteristic after shifting. An encoding portion performs systematic encoding of the information bits into which the dummy bits are inserted, and deletes the dummy bits from the results of the encoding to generate a systematic code, and a rate matching portion, performs rate matching such that the size of the systematic code is equal to a size determined by the physical channel transmission rate, and transmits the systematic code.

摘要： In an error control apparatus on a receiving side using a hybrid ARQ which combines an error correcting encoding method and an automatic repeat request method, a buffer stores hard decision result data or soft output data instead of soft decision information in order to reduce a memory capacity of the buffer, and re-encodes the data stored to be provided to a combiner. Alternatively, the number of bits of the data stored in the buffer is restricted or a memory included in a decoder is used as an HARQ buffer.

摘要： A receiver receives data transmitted from a transmitter. The data is stored in a buffer, and a reliability value of the data is computed by a computing unit. A determining unit determines reliability of the data by comparing a reliability value of existing data in the buffer and a reliability value of the data. When the reliability value of the data is higher than a predetermined value, the existing data is combined with the data. Then, an error correcting unit performs error correcting on combined data obtained, and outputs decoded bits. If the combined data includes many errors, retransmission of the data is requested to the transmitter. When the reliability value of the data is lower than the predetermined value, retransmission of data is directly requested without combining the data with the existing data.

摘要： The present invention is directed to a handover method, a base station, and a mobile station for a CDMA mobile communication system, to improve the efficiency of inter-frequency handover. Handover is achieved between a mobile station and distributed base stations and the like. The base stations have different traffic channel frequencies. In a normal mode, a signal unit transmitted through a traffic channel consists of four frames. In a compression mode, the base station temporally compresses two normal frames into a single frame period and then transmits the frames twice through the traffic channel. The mobile station switches the reception frequency of a present traffic channel and the reception frequency of a perch channel of the destination base station at intervals of two normal-mode frames at the head of each frame received from the perch channel. The mobile station then restores frames received from the traffic channel in the compression mode to the original frames and processes them. At the same time, the mobile station extracts a system frame number from two frames received from the perch channel.
