Methods used in control node and radio node and associated devices

A control node, comprising:

• a processor and non-transitory computer readable medium storing instructions, which when executed by the processor, cause the control node to perform:
• selecting one or more client radio nodes based on a Directional Link Interference Map (DLIM) for active links under control of the control node, wherein each of the one or more client radio nodes is served by a server radio node under control of the control node, wherein the DLIM identifies directional links that contribute interference to the active links and interference levels of the directional links;
• for each of the selected one or more client radio nodes, determining one or more candidate links other than an active link between the client radio node and its server radio node for replacing the active link, wherein each candidate link is between the client radio node and another radio node other than the server radio node;
• for each of the determined candidate links and active links,
• determining a set of sounding and sensing related parameters, wherein the set of sounding and sensing related parameters for a link includes a set of dedicated sounding and sensing related parameters for the link and a set of common sounding and sensing related parameters for the determined candidate links and active links, and wherein the set of common sounding and sensing related parameters includes a sounding and sensing period and a sounding and sensing interval;
• and
• transmitting the determined set of sounding and sensing related parameters to a transmitting node and a receiving node of the respective link.
