Abstract
The invention relates to sub macro cellular layers of a wireless communications system. An object of wireless communications system design is to reduce the number of base station sites required by increasing their range and or capacity. The term, “capacity” is used herein to refer to any suitable measure which provides an indication of how many conventional mobile terminals or other terminals are able to communicate effectively with a given antenna arrangement. Macro base station sites for cellular systems are particularly expensive, both in terms of the equipment required and the need for a geographical site for each cell site where, inter alia, large structures are frequently employed where planning permission is required. The present invention seeks to provide a system and method for reducing the effects of adjacent channel interference, especially in 3G CDMA base stations.
