Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The disclosure provides a remote interference management method, a gNB, an electronic device, a readable storage medium, and a base station for performing inter-base station interference coordination. The method includes steps of: determining, by a gNB, a mapping relationship between a gNB set ID and a RIM-RS according to received configuration information; transmitting, by the gNB, the RIM-RS according to the allocated gNB set ID and the mapping relationship; and/or performing RIM-RS detection, by the gNB, determining gNB set ID information through the detected RIM-RS according to the mapping relationship, and reporting the determined gNB set ID information. The present disclosure determines the mapping relationship between the gNB set ID and the RIM-RS according to the received configuration information, and further transmits and/or detects the RIM-RS based on the mapping relationship, thus simplifying signaling interaction information and improving the communication flexibility of the RIM-RS with multiple functions. The base station includes: a transceiver, configured to transmit signals and/or receive signals; and a processor, configured to: control the transceiver to receive a physical signal transmitted by a second base station and perform interference measurement based on the received physical signal; and control the transceiver to report an interference measurement result to the second base station or a management center, to cause the second base station to perform interference coordination for at least the first base station based on the interference measurement result reported by the first base station or configuration by the management center.
