US 2020/0007206 A1 · INTERFERENCE COORDINATION METHOD AND APPARATUS

Abstract

Embodiments of the present invention disclose an interference coordination method and apparatus. The method includes: receiving direction restriction information, where the direction restriction information includes angle restriction information, and the angle restriction information is used to indicate a restricted transmission direction; determining a signal preprocessing manner, where a transmission direction formed based on the signal preprocessing manner does not include the restricted transmission direction; and feeding back the signal preprocessing manner. According to the embodiments of the present invention, signaling overheads can be reduced, and an interference coordination application scenario can be expanded.
