摘要： A mobile communication system capable of improving the system throughput. A base station (1) divides one cell into three sectors. A common pilot channel is transmitted to a plurality of mobile stations in the sectors by beams (101-103) whose directivity is controlled by an adaptive antenna for each of the sectors. On the other hand, when a mobile station (2) communicates data with the base station (1), the base station transmits a data channel and an individual control channel to the mobile station (2) by using a beam (201) whose directivity is controlled individually. The mobile station (2) switches between the common pilot channel and the individual control channel from the base station (1) for estimating the communication path quality.

摘要： In soft hand over in a code division multi access mobile radio communication system, interference in a down link caused by transmission from a plurality of base stations for one mobile station, can be restricted. Control of transmission power is performed according to command from the mobile station only in the base station serving as a primary base station which has minimum propagation loss with the mobile station during soft hand over, and the base stations other than the primary base station perform transmission with restricting output. In comparison with the transmission power control performed by the conventional plural base station transmission, interference for the peripheral mobile station can be reduced to achieve higher down link capacity. Also, upon restricting transmission power of the base station other than the base stations having small propagation loss with the mobile station among base station group in soft hand over, by moderately attenuating the transmission power instead of restricting abruptly, degradation of the reception quality can be prevented when error is caused in selection of the base station.

摘要： A cellular type mobile communication system comprising a plurality of cells, a plurality of base stations disposed in the respective cells, and a mobile station located in the cells. On reception of a control command for a transmission power from the mobile station, each base station increases or decreases the transmission power in response to the control command. In addition, each base station renews the transmission power so that the transmission power after increased or decreased approaches a predetermined reference power.

摘要： A device acquires load information representing a load of radio communication performed between a base station and a plurality of communication terminals performing radio communication with the base station by using a radio resource allocated by the base station. The device sets in response to the acquired load information, from a first radio resource range and a second radio resource range, a radio resource range that the base station can allocate to an edge communication terminal whose channel quality is less than a predetermined threshold.

摘要： For a communication terminal performing radio communication, a base station acquires communication path quality information representing a communication path quality, which is the quality of a communication path with the communication terminal. The base station allocates power larger than reference transmission power as transmission power to an edge terminal configuring at least part of an edge terminal group configured by an edge terminal that is a communication terminal whose communication path quality is lower than a threshold quality, allocates the reference transmission power as the transmission power to an edge terminal configuring a remaining part of the edge terminal group.
