摘要： A wireless communication system comprises a mobile station and a base station, which use a plurality of communication channels and a pilot channel corresponding to at least one of the communication channels. The base station has a transmitting unit that employs at least one of the communication channels as a priority channel and transmits channel information of this priority channel and the other channels by use of a communication channel other than the pilot channel. The mobile station has a determining unit that determines a reception level of the pilot channel; an acquiring unit that acquires the channel information transmitted via the communication channel other than the pilot channel; and a deciding unit that decides, as an available communication channel, at least one of the communication channels based on both the channel information acquired by the acquiring unit and the reception level determined by the determining unit.

摘要： The present invention enables assignment to a terminal a sub-band having satisfactory communication quality. A reference-signal reception unit receives from a terminal a reference signal spreading over sub-bands. A communication-quality measurement unit measures the communication quality of each of the sub-bands on the basis of the reference signal. A sub-band assignment unit assigns one of the sub-bands to the terminal on the basis of the communication quality, for the terminal to perform wireless communication with the communication device. A reference-signal transmission unit transmits to the communication device a reference signal spreading over the sub-bands. A sub-band-assignment-information reception unit receives information on one of the sub-bands which is assigned to the terminal by the communication device on the basis of the reference signal. A data transmission unit transmits data to the communication device through the sub-band assigned to the terminal.

摘要： In transmission in which MIMO is applied, there have been problems that the number of variable parameters increases and the number of information bits necessary for control channel increases. When the number of simultaneous multiplex users in one frame increases, there is also a problem of increased control channel information in proportion to the number of users. Error correction coding is performed for the control channel information based on the Adaptive Modulation and Coding scheme, and the above error correction coded control channel information is transmitted after being modulated with a predetermined modulation scheme, and further, according to propagation condition, the coding rate in the above error correction coding is made variable.
