Spread spectrum communication system and base station thereof

A base station for managing a cell in a spread spectrum communication system comprising a plurality of cells which share common frequencies, which base station comprising:

• a first transmitting means for transmitting a reception load state of the own base station to other base stations managing other cells;
• a first receiving means for receiving reception load states of said other base stations from said other base stations managing said other cells;
• a second transmitting means for transmitting a signal having control information interpolated therein to each mobile station within the cell under management of said own base station, said control information.being used for controlling a transmission state of said each mobile station;
• a second receiving means for receiving a signal from said each mobile station within said cell under management of own base station;
• and
• a power control means for determining said control information for said each mobile station so as not to interfere with operations of said other base stations managing said other cells with reference to a reception level index of the signal from said each mobile station and said reception load states of said other base stations managing said other cells.
