Configuration method of almost blank subframe, apparatus and base station

Abstract

The invention discloses a configuration method of an almost blank subframe, an apparatus and a base station. The method comprises the following steps that an interference base station determines to configure an ABS subframe; according to the number of subframes needed by a user under the interference base station, a sum of downlink subframes in an ABS subframe configuration period and a congestion threshold value, the number of idle subframes of the interference base station is determined; the number of the ABS subframes which are needed by interfered base stations and are sent by the N interfered base stations is acquired; according to the number of idle subframes of the interference base station and the number of the ABS subframes which are needed by the interfered base stations and are sent by the N interfered base stations, the number of interference base station configuration ABS subframes is generated. By using the method, the apparatus and the base station of the invention, system performance is not deteriorated when the interference base station configures the ABS at a congestion state; ABS resource configuration is effectively controlled; the lowest resource demand of the user is satisfied and simultaneously a system state is balanced; the ABS is configured as much as possible and performance and a throughput capacity of an interfered base station edge user are increased; and a system resource utilization rate is increased too.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a configuration method, device and base station for almost blank subframes. Background technique [0002] In order to effectively solve the problems of coverage increase and offloading in indoor and hotspot scenarios, for example, LPN (LowPowerNode, low-power node) is introduced into the coverage of macro base stations to form a multi-layer network with the same coverage composed of different types of nodes. The network is called HetNet (Heterogeneous network, heterogeneous network). LPN includes picocell (Picocell), home base station (Femtocell) and relay node (RelayNode) with signal relay transmission, which can also be collectively referred to as micro base station; compared with traditional macro base station, micro base station has low power consumption, small size It is small, light and flexible, easy to cover blind spots, hotspot distribution and flexible...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, most ABS configuration strategies mainly consider the load of the micro base station, the amount of interference, user information or the number of edge interference users, resulting in the macro base station after configuring ABS subframes, the system resources cannot meet the minimum resource requirements of the macro base station users
