ABSAlmost Blank Subframe A Method and an apparatus for performing Carrier Aggregation using Multiple ABSAlmost Blank Subframe pattern in a macro cell base station of a wireless communication system with Heterogeneous Networks

摘要

One embodiment of a method for performing carrier aggregation using a plurality of ABS (Almost Blank Subframe) patterns in a macrocell base station of a wireless communication system connected to a heterogeneous network according to the present invention is to each of the macrocell base station and at least one small cell base station. When two or more different carriers are arranged, determining an ABS pattern having different patterns for each carrier; Determining a serving cell for a terminal among macrocells or small cells; And performing carrier aggregation for data transmission from the macrocell base station and the small cell base station to the terminal using the determined ABS pattern according to the determined serving cell.
