Resource scheduling method and device in heterogeneous network

Abstract

The invention discloses a resource scheduling method and device in a heterogeneous network. The method comprises the following steps: determining whether a to be scheduled terminal is an edge user of a micro station and whether the to be scheduled terminal is interfered by an adjacent macro station; if the to be scheduled terminal is an edge user of the micro station and interfered by an adjacent macro station, determining an interference macro station set interfering the to be scheduled terminal; determining an ABS sub-frame used by the to be scheduled terminal according to nearly blank sub-frame ABS pattern sent by each macro station in the received interference macro station set. The edge user interfered by the macro station is determined through the method disclosed by the invention so as to purposefully distribute the ABS sub-frame for the user; the interference macro station set of the to be scheduled terminal is determined so that the micro station is capable of distributing the ABS sub-frame sent by the corresponding interference macro station to the to be scheduled terminal to use; not only the reasonable use of the ABS sub-frame is guaranteed, but also the service quality of the to be scheduled terminal is effectively improved, and the aim of realizing interference coordination between the micro station and the macro station is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource scheduling method and device in a heterogeneous network. Background technique [0002] In order to effectively solve the coverage and distribution problems of macro stations in indoor and hotspot scenarios, low-power nodes (LPN, LowPowerNode) are introduced into the coverage of macro stations to form a multi-layer network with the same coverage composed of different types of nodes. The industry will Such a network is called a heterogeneous network (HetNet, Heterogeneous network). LPN includes picocell (Picocell), home base station (Femtocell) and relay node (RelayNode) with signal relay transmission. For the LPN here, it can also be collectively referred to as micro station; compared with traditional macro station, micro station has Low power consumption, small size, portability and flexibility, convenient for flexible deployment such as coverage patchi...
