    Abstract: 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.

    Abstract: In a CDMA transmitting apparatus, a cross-correlation value between different spreading-code sequences used to spread respective ones of a plurality of transmit signals is calculated, an interference interval of a spreading-code sequence is discriminated from the cross-correlation value calculated, and interference noise is reduced by halting transmission of at least one transmit signal, or partially altering at least one spreading-code sequence, with regard to all or part of a spreading-code sequence discriminated to be an interference interval.

    Abstract: In a code division multiple access communicating system, a base station has a receiving means receiving access signals from plural terminal apparatus, and an acknowledge information transmitting means collectively putting acknowledge information to reception of the access signals for the terminal apparatus in a transmission frame when the receiving means receives the access signals from the terminal apparatus and transmitting the frame to the plural terminal apparatus, while each of the terminal apparatus has an acknowledge information receiving means receiving a plural pieces of acknowledge information from the acknowledge information transmitting means of the base station, and a transmitting means again accessing to the base station according to the acknowledge information for its own terminal apparatus among the plural pieces of acknowledge information, thereby avoiding conflict of access timings between the terminal apparatus whose acknowledge information has been put, and thus suppressing a decrease of the throughput.

    Abstract: 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.
