Abstract
A terrestrial network node of a terrestrial mobile communication network is operated to simultaneously serve terrestrial and aerial coverage on a same carrier frequency. Such operation includes directing a first reception beam towards an aerial radio node. A second reception beam is directed towards a user equipment in the terrestrial mobile communication network. The signal received in the first reception beam is filtered to create a replica of a signal transmitted by the aerial radio node as received by the second reception beam. The replica is subtracted from the signal received by the second reception beam.
