A method for managing a terminal operated in an idle state is provided. The method includes entering a femto cell, determining whether a femto base station managing the femto cell has the same paging group as a macro base station managing a macro cell overlapping the femto cell, transmitting a first ranging code triggering a paging enable state to the femto base station if it is determined that the paging group is the same as the determination result, and receiving a paging message from the femto base station.

In a retransmitting method, at least one ARQ block included in a first PDU is fragmented into a plurality of ARQ sub-blocks, and at least one second PDU is generated from the plurality of ARQ sub-blocks. The second PDU includes a payload including an extended header and at least some of a plurality of ARQ sub-blocks. The extended header includes a field representing a sequence number of the first ARQ sub-block belonging to the payload.

There is provided a method for transmitting data by a base station (BS) in a multicast broadcast service (MBS) supporting multiple carriers in a wireless communication system. The method comprises receiving a switching request message indicating an E-MBS service requested by a mobile station (MS), from the MS, transmitting a switching response message including information regarding a switching start time among a plurality of carriers set in the MS and transmitting data regarding an E-MBS service requested by the MS to the MS through a primary carrier, starting from the switching start time.Alternatively, there is provided a method for receiving data by a mobile station (MS) in a multicast broadcast service (MBS) supporting multiple carriers in a wireless communication system. The method comprises transmitting a switching request message indicating an E-MBS service requested by the MS to a BS, receiving a switching response message including information regarding a switching start time among a plurality of carriers set in the MS from the BS, switching from a secondary carrier to a primary carrier at the switching start time and receiving data regarding an E-MBS service requested by the MS from the BS through the primary carrier.

The subscriber station of claim 15, wherein the uplink data includes data to be transmitted, and a header having information on the data and the subscriber, and the uplink data generator adds the subheader includDisclosed is a method and device for requesting and reporting channel quality information in a mobile communication system. An uplink radio resource for a subscriber station having data to transmit is allocated and a CQI indicator for requesting channel quality information is added to the allocation information to be transmitted to a subscriber station. The subscriber station having received the uplink radio resource allocation information generates channel quality information by measuring the radio channel quality for communication with the base station according to existence of the indicator and transmits desired uplink data having the generated channel quality information to the base station. As a result, the seamless and efficient channel quality report can be performed in the wireless communication system, and the optical modulation and the channel coding level can be adapted for the subscriber to transmit or receive the data corresponding to the channel quality. ing the channel quality information to the header of the uplink data.

There are provided a method and an apparatus for scanning in a mobile communication system supporting a multi-carrier. For this, the scanning method includes: in a mobile station supporting a multi-carrier including a primary carrier and a secondary carrier, requesting allocation of a scanning interval to a serving base station by using the primary carrier; receiving a response message for designating the scanning interval and a carrier to be used for scanning from the serving base station; and scanning neighbor base stations by using the carrier designated by the response message in the scanning interval. Transaction data is continuously transmitted and received through the remaining carriers while scanning the neighbor base stations by using the primary carrier or the secondary carrier without interruption.

Provided is a method for obtaining superframe header (SFH) information in a neighboring base station advertisement (NBR-ADV) message at a terminal. In the method, a NBR-ADV message having SFH information set per each carrier is received from a serving base station. The SFH information of each carrier is obtained from the NBR-ADV message. In the obtaining the SFH information of each carrier, SFH information of a corresponding carrier is obtained based on SFH information of a previous carrier when a predetermined field is set as a predetermined value.
