Claim:
1. A method of performing a channel measurement at a User Equipment (UE) in a wireless communication system, the method comprising: receiving a handover command message including subframe allocation information of a target cell indicating a measurement restriction set related to a channel measurement from a serving cell via a physical layer, wherein the target cell is interfered with by a neighbor cell and participates in almost blank subframe (ABS)-based interference coordination, wherein the measurement restriction set indicates a subframe pattern in which channel measurement is allowed based on the ABS-based interference coordination, and wherein the UE is not able to receive, from the target cell via higher layer signaling, the subframe allocation information of the target cell before the UE handover to the target cell is completed, receiving a signal from the target cell in a time interval corresponding to the measurement restriction set, measuring a channel of the target cell using the received signal, and determining whether to perform handover to the target cell based on the measurement of the target cell.
