Title: WIRELESS COMMUNICATION SYSTEM WITH DISCRIMINATION BETWEEN EXTRANEOUS RECEIVED SIGNALS
Abstract:
A wireless communication system comprising base stations and remotely located terminal units. The base stations and the remotely located terminal units communicate data over operational wireless communication links between them. The communication links are assigned to respective sub-channels comprising tiles separated by frequency and time. At least the base stations have detectors for analysing extraneous received signals in unassigned tiles of the communication links. The detectors discriminate between a first type of extraneous signals detected in unassigned tiles of one sub-frame and also detected in other unassigned tiles, and a second type of extraneous signals detected in the unassigned tiles but not detected in other unassigned tiles. The reaction of the base stations to detection of the first type of extraneous signals is different from the reaction of the base stations to detection of the second type of extraneous signals.
