Abstract
A method for reducing interference between FDD and a TDD interfering radio networks including identifying respective radio entities for which the interferences should be reduced; defining a time pattern comprising time slots on each of the interfered channels, and receive time intervals for radio entities that may be interfered, and aligning the time patterns so that receive time intervals for the radio entities that are potentially exposed to interferences, overlap each other. The radio entity that might create interference to the radio entity of the pre-defined type of the other network, is prevented from transmitting communications that might create e substantial interference to the radio entity associated with the other radio network, and communications transmitted to some radio entities of the pre-defined types that might experience interference, are scheduled at intervals in which communications are received with substantially reduced interference.
