Abstract

The invention relates to the technical field of communication, and aims to solve the problem of co-channel interference among micro-base stations FAPs in the prior art. The invention provides a method, a device and a system for distributing subcarrier groups. The method in a micro base station configuration center comprises the following steps of: determining the adjacent micro-base station of which the coverage is superposed with that of a network-accessed micro-base station by the micro-base station configuration center; searching use information of PUSC (Partially Used Sub-Carrier) domain subcarrier groups used by the adjacent micro-base station, and distributing a PUSC domain subcarrier group which is different from the PUSC domain subcarrier group of the adjacent micro-base station to the PUSC domain of the micro-base station; and sending the distributed PUSC domain subcarrier group information to the micro-base station. Different subcarrier groups can be dynamically distributed to the FAPs, among which co-channel interference possibly produce, through the micro-base station configuration center, thereby eliminating co-channel interference between every two adjacent FAPs.

Description

technical field [0001] The present invention relates to the technical field of communications, and specifically relates to a method, device and system for allocating subcarrier groups. Background technique [0002] A Femtocell Access Point (FAP) in a Worldwide Interoperability for Microwave Access (WiMAX) network is a low-power WiMAX base station. This kind of micro base station provides wireless coverage in a small range, and is mainly used in indoor homes and small home office (SOHO: Small Office Home Office) environments, so it is also called a micro base station. It uses a wired broadband network (such as a DSL / IP network, etc.) for access, and the wired broadband network here may belong to different operators from the WiMAX network. The MS connects to the FAP through the air interface, accesses the WiMAX network, and interacts with the signaling plane of the WiMAX core network data through the wired broadband network. [0003] WiMAX FAP provides access services for Wi...
