Patent ID: 8446869

Claim:
An operation method of a femto Base Station (BS) in a wireless communication system supporting a femtocell, the method comprising: configuring a subframe set comprising at least two types of subframes among subframes having predefined different structures; and if a duration of a subframe carrying the subframe set arrives, transmitting one of the subframes comprised in the subframe set according to predefined order, wherein the duration is discontinuously distributed in a frame and no subframe is transmitted in a period other than the duration, wherein the subframes having the predefined different structures comprise: a first type subframe comprising a synchronization signal and a Master Information Block (MIB); a second type subframe comprising the synchronization signal; a third type subframe comprising the synchronization signal and system information; a fourth type subframe comprising the synchronization signal, the MIB, and the system information; and a fifth type subframe comprising the system information, and wherein the synchronization signal included in the subframe set is the same, in a physical layer structure, as a synchronization signal transmitted through an operation frequency band of the femtocell BS, and wherein the subframe set is transmitted during preset burst duration every preset system information transmission period, and the system information transmission period and the burst duration are defined in a unit of frame.
