    Abstract: The present invention relates to a method and apparatus for transmitting a bandwidth request (BR) header in a wireless communication system. User equipment transmits a standalone BR header to a base station through a first uplink (UL) resource allocated by a BR-acknowledgement (ACK) A-MAP information element (IE), receives from the base station a hybrid automatic repeat request (HARQ)-non-acknowledgement (NACK) which indicates the base station has not successfully received the standalone BR header, receives a CDMA allocation A-MAP IE from the base station, and retransmits the standalone BR header through a second UL resource allocated by the CDMA allocation A-MAP IE.

    Abstract: A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed. A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary superframe header (S-SFH) change cycle from a base station (BS), and receiving a primary superframe header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary superframe header subpacket information elements (S-SFH SP IEs) from the base station (BS). Once each of the plurality of S-SFH SP IEs is changed, each of the plurality of S-SFH SP IEs remains unchanged during one or more S-SFH change cycles.

    Abstract: The present invention relates to a method for updating secondary carrier information for preemptively allocating secondary carriers during handover and an apparatus for carrying out the method. A method in which a terminal performs handover in a broadband access system that supports multiple carriers according to one embodiment of the present invention comprises: a step in which a target base station receives, from a serving base station, a first message including carrier allocation information on at least one secondary carrier preemptively allocated to the terminal; a step of performing network reentry with the target base station; and judging whether the multi-carrier configuration of the serving base station and the multi-carrier configuration of the target base station are the same, and, if the configurations are different from each other, transmitting, to the target base station, a second message for requesting multi-carrier capability negotiation.
