Methods used in control nodes, and associated control nodes

A network node of a first network for determining interference from a second network, comprising:

• a processor;
• and
• a memory containing instructions which, when executed by the processor, cause the network node to perform operations to:
• determine first sounding and sensing related parameters for radio nodes of the first network that communicate using directional links utilizing beam-forming, wherein sounding and sensing, utilizing the first sounding and sensing related parameters, by the radio nodes of the first network during a sounding and sensing window provide measurements for determining intra-network interference for the first network;
• receive second sounding and sensing related parameters for radio nodes of the second network that communicate using directional links utilizing beam-forming, wherein the second sounding and sensing related parameters pertain to radio nodes of the second network;
• adjust the sounding and sensing window of the first network, based on the second sounding and sensing related parameters, to sense effects of sounding of the radio nodes of the second network on radio nodes of the first network;
• and
• apply the adjusted sounding and sensing window to sound and sense in the first network to obtain measurements to determine inter-network interference from the second network on the radio nodes of the first network.
