Abstract
A base station of a second system performs communication using a frequency adjacent to a frequency employed by communication between a base station and a mobile station of a first system. When the mobile station is close to the base station , the communication of the base station undergoes interference by the leakage power of the mobile station . To avoid the interference, the transmission is halted of the mobile station of the first system, which provides the interference by the leakage power.
