Interference and traffic pattern database

A node associated with one or more cellular communications networks, comprising:

• one or more processors;
• and
• memory containing instructions executable by the one or more processors whereby the node is operable to:
• obtain position-pair-dependent interference related information for pairs of positions, the position-pair-dependent interference related information comprising, for each pair of positions comprising a first position and a second position, information regarding interference caused by wireless transmissions originating at the first position to wireless receptions at the second position;
• identifying one or more interfered node and interfering node pairs having an interference level that is greater than a predefined threshold based on the position-pair-dependent interference related information for the position of a receive node;
• store information comprising the position-pair-dependent interference related information in one or more databases;
• and
• provide access to the one or more databases to enable taking one or more actions with respect to mitigating interference to the receive node from at least one of the interfering nodes as dominant interferer in the one or more interfered node and interfering node pairs where the one or more actions including at least one action chosen from the group consisting of:
• performing interference cancellation;
• and
• performing interference rejection combining.
