1. A base station device, comprising:
a processing circuitry configured to:
based on a conflicting beam list, determine that at least one conflicting beam is included in a set of transmitting beams to be used for downlink transmission from a local cell in a future specific period;
in response to the determining, send beam scheduling information for the future specific period to a base station of an adjacent cell, the beam scheduling information including at least information on time-frequency resources allocated to the at least one conflicting beam by the local cell,
wherein the conflicting beam list indicates a set of conflicting beams of the local cell involved in an inter-cell interference between the local cell and the adjacent cell, and
wherein the processing circuitry is further configured to:
receive, from the base station of the adjacent cell, time information about when an interference from the local cell is measured by a second UE in the adjacent cell;
based on the time information, determine a particular transmitting beam of the local cell interfering the second UE;
determine the particular transmitting beam to be a conflicting beam; and
store, in the conflicting beam list, a beam index of the particular transmitting beam.
