摘要： A Handover apparatus and method of a Mobile Station (MS) in a wireless communication system in which at least one small cell resides in a macro cell includes, when entering a neighboring small cell, checking a movement speed of the MS. The method also includes determining whether to hand over to the small cell by taking into account the movement speed of the MS. When it is determined not to hand over to the small cell, that MS transmits small cell penetration information to a macro Base Station (BS); allocates a macro only resource from the macro BS; and communicates with the macro BS in the small cell using the macro only resource allocated from the macro BS.
