Abstract:
1. A method in a first radio network node (HBS) transmitting a radio signal at a first output power level in a first cell, the method comprising the steps of: performing one or more radio measurements in the first cell on an uplink (UL) radio signal transmitted by one or more user equipments (UEs) served by a second radio network node and on a downlink (DL) radio signal transmitted by the second radio network node, identifying one of the one or more UEs served by the second radio network node that experiences interference from a DL transmission from the first radio network node based on the one or more performed radio measurements, estimating an interference experienced by the identified UE caused by the DL transmission from the first radio network node based on the one or more performed radio measurements, and modifying the first output power level of the first radio network node based on the estimated interference to reduce the interference from the first radio network node experienced by the identified UE.
