Disclosed is a method of a handover in a wireless communication system. The method includes transmitting a handover request message to the service BS, and receiving a handover command message from the service BS in response to the handover request message. Multi-carriers are assigned to a terminal in advance right before a handover, and all or some of the multi-carriers are activated right after the handover. Therefore, multi-carrier are effectively utilized.

Method receiving Multicast Broadcast Service (MBS) in a wireless communication system is provided. The method comprises receiving a Dynamic Service Addition (DSA) message through a primary carrier, from a Base Station (BS); switching from the primary carrier to a secondary carrier based on the DSA message; receiving an MBS Configuration message through the secondary carrier, from the BS; and receiving MBS data through the secondary carrier based on the MBS Configuration message, from the BS.

A method of transmitting data for reducing interference in a hierarchical cell structure including a macro base station (BS) providing multi carriers and a femto BS providing a single carrier includes performing a channel scan within an interfered carrier to acquire channel state information and neighbor femto BS information if interference with the femto BS occurs; transmitting a channel measurement report including the channel state information and the neighbor femto BS information to the macro BS; and transmitting data through a carrier changed by receiving carrier change information from the macro BS.

There is provided a method for handover of a terminal in a wireless access system using multi-carrier operation. The method comprises: receiving a handover command message from a serving base station; and performing network reentry to a target base station based on the handover command message, wherein the handover command message includes information required for handover to the target base station and information on whether the target base station supports handover using multi-carriers. Accordingly, it is possible to efficiently perform the handover in the wireless access system supporting the multi-carriers.

The present invention relates to a femtocell search method for a handover from a macrocell to a femtocell. The present invention relates to a method for a terminal that accesses a macrocell to search a femtocell in an environment where a plurality of femtocells are overlapped in one macrocell. The terminal searches a femtocell by using a dummy preamble in order to minimize the size of neighbor cell lists broadcasted from the macrocell to the terminal. Therefore, according to the present invention, an MAC overhead can be minimized by eliminating neighbor femtocell lists in a mobile neighbor advertisement (MOB_NBR_ADV) message broadcasted from the macrocell, and the terminal can search a femtocell with a minimum scanning load by checking only a femtocell dummy preamble in a dedicated symbol of the macrocell.

The present invention provides a method of a Base Station (BS) updating system information using a superframe structure in a wireless communication system, comprising transmitting a primary header including system scheduling information pertinent to an update of the system information and transmitting an updated secondary header. The system scheduling information comprises secondary header change state information indicating a change state of the updated secondary header, secondary header applying information indicating whether the secondary header change state information is applied to a current system, and a secondary header change indicator indicating the updated secondary header.
