Reducing interference caused by an atmospheric duct in a mobile communication system

摘要

A base station (14) in a mobile communication system operating according to a synchronized time division scheme comprises an antenna (26), a radio communication unit (24) for communicating with mobile stations of the system and an interference investigating unit (28) comprising a link quality measuring element (30), which obtains link quality measurements that are measured in the base station during uplink communication (UL) between at least one mobile station and the base station, a link quality evaluation element (32) that compares link quality measurements of at least one uplink channel with a link quality threshold and determines that the uplink channel is interfered by another base station if the link quality threshold is exceeded, a base station identifying element (34) that identifies the other base station via signals broadcast by the other base station and an interference limiting element (36) configured to perform an interference limitation activity based on the identification.
