    摘要: A synchronization channel is generated by generating, as a P-SCH basic waveform, a signal sequence in which codes with constant amplitude in a frequency domain are placed at intervals of a predetermined number of subcarriers; transforming the signal sequence into a time domain; multiplying the signal sequence transformed into the time domain with a predetermined code sequence; retransforming the signal sequence multiplied with the predetermined code sequence into the frequency domain; generating an S-SCH signal sequence; and multiplexing the signal sequence retransformed into the frequency domain and the S-SCH signal sequence.

    摘要: In a radio communication system, a user terminal transmits a reservation packet to a base station using a common control channel (1), and the base station assigns an uplink data channel to the user terminal according to the reservation packet, and assigns a first shared control channel (2b) to the user terminal in association with the uplink data channel, and the mobile station transmits a control signal to the base station using the associated uplink shared control channel. According to status of radio communication, the base station may assign beforehand a second uplink shared control channel (2a) for which occupation by the user terminal is permitted only while the user terminal is performing communication.

    摘要: A disclosed base station transmits a broadcast channel to a user device a predefined number of times in a predetermined cycle for communication with the user device. The base station includes a repetition unit configured to repeat the broadcast channel, after the broadcast channel is channel-coded, for the predefined number of times to generate multiple broadcast channels; and a signal waveform changing unit configured to process the generated broadcast channels such that the processed broadcast channels have different signal waveforms. Positions of the broadcast channels in the order of transmission in the predetermined cycle are associated with the signal waveforms of the broadcast channels.

    摘要: In a radio communication system including a plurality of base stations and a plurality of mobile stations, a base station includes a reception timing difference report unit measuring a reception timing difference of reference signals transmitted from neighboring base stations, and reporting the reception timing difference to one or more base stations. A base station has a transmission timing difference computation unit computing a transmission timing difference of reference signals between the base station and neighboring base stations based on the reception timing difference, and a transmission timing difference information report unit reporting the transmission timing difference to the mobile station. The mobile station further includes a cell search unit performing cell search on a cell search range limited based on the transmission timing difference transmitted from the base station.
