METHOD AND APPARATUS FOR PERFORMING CARRIER AGGREGATION USING ABS PATTERNS IN MACRO eNB OF WIRELESS COMMUNICATION SYSTEM CONNECTED TO HETEROGENEOUS NETWORK

摘要

Methods and apparatuses are provided for performing carrier aggregation (CA) using a plurality of almost blank subframe (ABS) patterns in a macro enhanced Node B (eNB) of a wireless communication system connected to a heterogeneous network. An ABS pattern having a different pattern is determined for each component carrier (CC), when two or more carriers are deployed in each of the macro eNB and at least one small cell eNB. A serving cell for each user equipment (UE) is determined for each CC, from among a macro cell and a small cell. CA is performed for data transmission to each UE using the determined ABS pattern, in accordance with each determined serving cell.
