    摘要: Mobile station notifies base station of identification information of base stations searched by searching as a search list, and the base station notifies the mobile station of base stations which are not regarded as prestored neighbor base stations and base stations which are in an unusable base station list, of the base stations in the notified search list, as an NG list. If necessity of handover is increased, the mobile station receiving the notification executes handover to base stations (for example, base station) in the search list other than the base stations included in the NG list.

    摘要: In step 5a, a mobile-station measures a reception level and an interference level with the other base-stations, for a base-station considered as a communication partner. In step 5b, the mobile-station transmits a measurement result obtained in step 5a as control information to the base-station considered as the communication partner. In step 5c, the base-station determines a transmission format in a transmission format candidate group used for the transmission to the mobile-station, on the basis of the control information, etc. If the base-station discriminates that an area where the mobile-station considered as the transmission destination is located has a great influence since an interference level indicated by the control information received from the mobile-station exceeds a preset threshold value, the base-station determines use of a transmission format in which repetition is executed at more than two times after executing interleaving resistant to the interference, in the transmission format candidate group.

    摘要: On the basis of control information for CQI transmission of which a base station notifies a mobile station, the mobile station transmits CQI information for each sub-frame in a case of best effort type service or transmits the base station the CQI information at one time for every four sub-frames in a case of rate preservation type service.

    摘要: In a base station, after CRC is added to transmission data as a detection code, the transmission data is subjected to error-correcting coding using a convolutional code based on tail biting, divided into four frames of P-BCH and transmitted. For this reason, at a mobile station, even if reception (synthesis) is started from any frame of P-BCH represented as (b-1) to (b-4), a cyclic structure of the transmission signal is maintained due to the tail biting and reception data shifted by unit of frame can be obtained. For this reason, at the mobile station, even if a leading frame is unknown, decoding can be executed by one-time error-correcting decoding. A result of the decoding is subjected to CRC detection in four frame timings, the leading frame is detected and the transmission data is restored.
