Spread spectrum communication system and base station thereof

摘要

A spread spectrum communication system includes a plurality of cells which share common frequencies. Each base station managing each cell includes transmitters for transmitting a reception load state of the base station to other base stations managing other cells. Receivers for receiving reception load states of the other base stations and transmitters for transmitting a signal having control information interpolated therein to each mobile station within the cell under management are included in the system. The control information is used for controlling a transmission station of each mobile station. A second receiver for receiving a signal from each mobile station within the cell under management and a power control are included for determining the control information for each mobile station so as not to interfere with operations of the other base stations managing the other cells with reference to a reception level index of the signal from each mobile station and the reception load states of the other base stations managing the other cells.
