摘要： An object of the present invention is to reduce the volume of a control signal and shorten a delay of processing in a system comprising a base station configured to transmit a pilot signal at a predetermined transmission power and a mobile station configured to transmit a preamble prior to transmission/reception of data. A mobile station comprises means for spreading the preamble with a spreading code corresponding to a reception power or a signal interference ratio of the pilot signal at the host station, based on a correspondence between the spreading code and, the reception power or the signal interference ratio of the pilot signal at the host station (power code determiner and transmitted signal converter), and means for transmitting the preamble after the spreading process (transmitter); and a base station comprises means for determining a transmission power or a downlink transmission rate for a signal directed to the mobile station, according to the spreading code of the preamble received from the mobile station, based on the correspondence between the spreading code, and the reception power or the signal interference ratio of the pilot signal at the mobile station (spreading code measuring part, estimator, and transmission rate determiner).

摘要： In mobile communication system 100 according to the present invention, mobile station 1 is camped on cell C10 established by base station B10. In the cell C10, there exist indoor cells C11-C13 and outdoor cells C21, C22 as neighboring cells. Mobile station 1 measures received levels of cells C10-C13, C21, C22 and determines cell types of the respective cells, i.e., whether each cell is an indoor cell or not, based on broadcast information M1. Mobile station 1 selects a cell as a reselection target on the basis of the received levels and cell types.
