Abstract

The invention discloses an interference adjustment processing method and device. The method comprises that a macrocell receives the amount of interfered terminals and the utilization rate of almost bland subframes (ABS) of a microcell covered by the macrocell; and the macrocell adjusts the ABS ratio according to load information of the macrocell as well as the amount of interfered terminals and the utilization rate of the ABS of the microcell. The load information comprises the GBR PRB utilization rate and the GBR DL PRB utilization rate; and the ABS ratio is the ratio of the ABS amount in the ABS mode period to the amount of all down subframes in the ABS mode period. The problem that the ABS utilization rate reported to the macrocell by the microcell cannot reflect the practical ABS utilization rate in the prior art is solved, and further the macrocell provides the accurate ABS ratio for the microcell covered by the macrocell.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an interference adjustment processing method and device. Background technique [0002] The inter-cell interference (eICIC) technology is an enhanced inter-cell interference coordination technology, which is mainly applicable to heterogeneous networks. The traditional macro cell network has the characteristics of "emphasis on outdoor, light on indoor", "recombined network, light on hot spot", etc., and it is not enough to consider the application of the growing hot spot users. Therefore, it is necessary to add low-power nodes in the macro cell. These nodes include A pico cell (pico), a home base station (femto), a relay station (relay), etc., these nodes form a heterogeneous network together. In heterogeneous networks, new interference scenarios will be introduced. How to provide high-quality services as much as possible under these interference scenarios is a topic of common c...
