<p>A CDMA wireless system which exchanges a signal between a plurality of mobile stations and a wireless base station by a CDMA (Code Division Multiple Access) method includes first and second hierarchical cells, and a base station control device. The first and second hierarchical cells constitute hierarchical cover areas of the wireless base station and are different in only transmission/reception frequency. The base station control device preferentially hands over a mobile station having a low spread rate among the mobile stations to either one of the first and second hierarchical cells. An interference wave suppressing method in this system is also disclosed. <IMAGE></p> |
