MANAGING EXTERNAL INTERFERENCE IN A WIRELESS NETWORK

摘要

A method and corresponding apparatus are provided for configuring a wireless network comprising a plurality of nodes to mitigate effects of an external interference source. A subset of nodes of the plurality of nodes are configured to simultaneously participate in an external interference sampling process in which each node of the subset of nodes samples signals received by an antenna array of that node. A measurement report, comprising a signal source angle and a received signal strength, is received from a node. A location of the external interference source is firstly estimated using the measurement report received from the node. The external interference source is then characterised using the estimated location of the external interference source and the received signal strength to calculate for the external interference source at least one of: a source power; a beam width; an antenna bearing; and a front-to-back transmission ratio. Finally the plurality of nodes are configured to mitigate the effects of the external interference source in dependence on a result of the characterising step.
