Abstract
An apparatus and method for reducing interference between an uplink transmitter of a space-based wireless communication system and an uplink or downlink receiver of a terrestrial wireless communication system are described. The space-based system may be a Fixed Satellite Service (FSS) system and the terrestrial system may be a Local Multipoint Distribution Service (LMDS) system. An ordered list of preferred uplink transmission frequencies is assigned to all FSS uplinks located in a particular cell of the LMDS system. Different ordered lists are used in different cells of the LMDS system, while uplinks located in the same cell can utilize the same ordered list. A given potentially-interfering uplink transmitter selects an uplink transmission frequency from the appropriate ordered list if the uplink is unable to operate outside the LMDS frequency band and there are no gaps in the LMDS spectrum which can accommodate the uplink transmission. The ordered list may be selected by the LMDS service provider such that the impact of interference from FSS uplinks can be readily predicted and minimized. The invention thus allows simultaneous access to a shared frequency band for both LMDS and FSS systems.
