US 2017/0288840 A1 · Interference adjustment Processing Method and Device

Abstract

An interference adjustment processing method and device are provided. In the interference adjustment processing method, a macro cell receives the number of interfered UEs and an Almost Blank Subframe (ABS) utilization rate from a micro cell in a coverage of the macro cell; and the macro cell adjusts an ABS proportion according to load information of the macro cell, the number of the interfered UEs under the micro cell and the ABS utilization rate, wherein the load information comprises a Guaranteed Bit Rate Physical Resource Block (GBR PRB) utilization rate and a Guaranteed Bit Rate Downlink Physical Resource Block (GBR DL PRB) utilization rate, and the ABS proportion is a ratio of the number of ABSs in an ABS pattern period to a total number of downlink subframes in the ABS pattern period.
