CONTROLLING INTERFERENCE IN A CELL OF A WIRELESS TELECOMMUNICATIONS SYSTEM

摘要

The present invention provides an interference controller and method for limiting in one cell the effect of interference generated by other cells of a wireless telecommunications system, each cell of the wireless telecommunications system having a central terminal and a plurality of subscriber terminals, communication between a central terminal and a subscriber terminal being arranged to occur over a wireless link, and a plurality of code division multiplexed channels being provided within a single frequency channel to enable data items pertaining to a plurality of wireless links to be transmitted simultaneously within different code division multiplexed channels of said single frequency channel. The interference controller comprises an analyser for comparing with predetermined criteria parameters within the cell indicative of whether the code division multiplexed channels are subject to interference from signals generated by said other cells; and a channel controller, responsive to the analyser, to selectively prevent code division multiplexed channels from being used in order to reduce the effect of the interference from said other cells. In preferred embodiments, the interference controller is provided within a central terminal of at least one cell of the wireless telecommunications system.
