    摘要: An improvement in the efficiency of downloading transmission data than conventional. This information downloading apparatus downloads different sets of information for every predetermined group to which a mobile terminal belongs. This apparatus comprises a channel selecting means for selecting an information channel for transmitting transmission data out of information channels and a transmitting means for transmitting transmission data by utilizing the selected information channel. The channel selecting means selects an information channel so as to transmit transmission data with different addresses through different information channels. The transmitting means transmits, for every group, information on the presence of transmission data, on an information channel to be used when transmission data is present, and on the data length of transmission data through a control channel. The control channel comprises time slots related with their respective groups.

    摘要: A radio communication system where a connection between a controlled radio communication apparatus and a controlling radio communication apparatus is registered. A controlling radio communication apparatus sends vacant slot information indicative of a vacant time division multiplexing time slot to a controlled radio communication apparatus, the controlled radio communication apparatus sends a connection register request signal to the controlling radio communication apparatus using a vacant time division multiplexing time slot based on the vacant slot information, the controlling radio communication apparatus allocates the vacant time division multiplexing time slot to the controlled radio communication apparatus that sent the connection register request signal based on the received connection register request signal, thereby registering the connection of the controlled radio communication apparatus, and the controlled radio communication apparatus sends a control signal using the time division multiplexing time slot allocated by the first radio communication apparatus. With this structure, it is possible to automatically register a connection of a controlled radio communication apparatus.

    摘要: Sub-channels are defined for a physical random access channel of a wireless time division duplex communication system using code division multiple access. The sub-channels carry information between system users and a system network. A series of radio frames have a sequence of timeslots. For a particular timeslot number of the sequence, each sub-channel of the particular timeslot number is uniquely defined by one radio frame of the series.

    摘要: A method and device are described for determining whether or not reserved bits of a field are assigned a function so that the mobile station may easily be adapted to perform enhanced functions. Such a determination enables first generation mobile stations to perform enhanced functions using bits which are initially reserved but may be assigned to service or function in later generations of the protocols. An indication of whether or not the reserved bits have been assigned a function may be sent on a broadcast channel by a usage information element. If the usage information element indicates that the reserved bits have not been assigned any service, such as power control, time alignment or short message services, the reserved bit may be used to enhance functions, such as equalization and synchronization. The method and device may further provide for improved decoding of the coded superframe phase/packet channel feedback (CSFP/PCF) field. Because the superframe phase (SFP) information is known when looking at the remaining bits from the start and end of the broadcast information, the number of possible codewords in the CSFP/PCF filed may be reduced in the decoding process. Also, the length of a codeword to be decoded may be reduced based on a usage information element sent on the broadcast channel which indicates whether a reserved bit in the CSFP/PCF field is still reserved. More generally, the block code of any channel coded word, not necessarily packet data may be effectively reduced based on knowledge of some information in the coded word. Decoding performance is improved by shortening the length of the codewords to be decoded because the shorter codewords are less susceptible to bit errors.
