Cross-link interference measurement method, apparatus, base station and controller

Abstract

A method, apparatus, base station, and controller for cross-link interference measurement are disclosed, relating to the field of communication technology. The controller sends configuration information for an interference measurement window to a victim base station and resource configuration information for measurement signals to both the victim and interfering base stations. The interfering base station sends measurement signals to the victim base station using different beams. The victim base station measures the CLI value of the beam corresponding to each measurement signal within the interference measurement window and reports the beam measurement results to the controller. The controller then coordinates inter-base station scheduling based on the beam measurement results. Applying the technical solution provided in this application can suppress CLI in F-TDD communication systems, improve the performance of F-TDD communication systems, reduce the complexity of interference measurement performed by the victim base station, and save energy for the victim base station.
