Exchange of ul interference detection related information

A base station, comprising:

• a transceiver that receives uplink interference detection related information and distribution information distributed from a first base station;
• and
• a processor that:
• updates the distribution information;
• and
• checks whether to transmit the uplink interference detection related information to other base stations based on the updated distribution information, wherein the transceiver transmits or stops transmitting the uplink interference detection related information according to the checking result.

A control node, comprising:

• a transceiver that:
• receives uplink interference detection related information from at least one base station;
• and
• distributes a list of the uplink interference detection related information to target base stations.
