TIME DOMAIN INTERFERENCE COORDINATION METHOD AND NETWORK DEVICE

摘要

Disclosed in the present invention is a time domain interference coordination method, comprising: when the load of a macro cell is larger than or equal to a load threshold or when a timer reaches the preset time of a system, a network device obtaining a first almost blank subframe ABS subframe ratio parameter of the macro cell and at least one cell range extension CRE parameter, the at least one cell range extension CRE parameter being a CRE parameter between the macro cell and at least one micro cell, and the at least one micro cell being a micro cell within the coverage range of the macro cell; the network device configuring the first ABS subframe ratio parameter to the macro cell, and configuring the at least one CRE parameter to the macro cell and the at least one micro cell. The method of the present invention enables an expansion of the coverage range of the micro cell when the load of the macro cell is larger than or equal to the load threshold, as a result of which the at least one micro cell adsorbs user equipment UE belonging partially to the macro cell, to reduce the load of the macro cell.
