Abstract

The invention discloses a method and apparatus for realizing almost blank subframe (ABS) configuration. The method comprises: an interference base station obtains ABS usage information sent by N base stations under interference; according to the ABS usage information, the number of configurable ABSs of the interference base station, and ABS adjusting states of the base stations under interference, the number of first configurable ABSs and the number of second configuration ABSs are determined; and the number of ABSs configured to the interference base station is determined based on the number of second configuration ABSs of the N base stations under interference and N interference levels. According to the embodiment of the invention, during the ABS adjustment process, the resource demands of the interference base station and the base stations under interference as well as the interference levels corresponding to the base stations under interference are taken into consideration, so that ABS configuration is balanced between the demand and the interference. Meanwhile, problems of long convergence time of ABS configuration and jittering existence are solved and the system stability is improved, so that objectives of edge user interference reduction, system performance improvement and throughput capacity enhancement can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for configuring almost blank subframe ABSs. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) communication system, it is necessary to effectively solve the problems of network coverage and network capacity increase in indoor and hotspot scenarios, for which HetNet (Heterogeneous network, heterogeneous network) is introduced. HetNet introduces LPN (LowPowerNode, low-power node) within the coverage of the macro base station to form a multi-layer network with the same coverage composed of different types of nodes. LPN can also be called a micro base station, including a picocell (Picocell), a home base station (Femtocell) and a relay node (RelayNode) with signal relay transmission. Compared with the traditional macro base station, it has low power consumption and small size , light and flexible, easy to cover bli...
