Abstract
A process of assigning frequencies uses propagation loss in a CDMA communication system. A base station measures propagation loss over a channel between the base station and a mobile station. If the measured propagation loss is greater than a certain fixed value, the base station determines that since the mobile station is present in a position distant from the base station, the mobile station may possibly interfere with a base station of another CDMA communication system. The base station assigns a frequency channel which is not adjacent to the frequency band assigned to the other CDMA communication system to the mobile station.
