    摘要: The present invention relates to a handover method for a mobile communication system. The handover method according to the present invention informs a current state to a serving base station(BS) when a re-entry process has been delayed or a handover has failed due to an error occurred in the handover procedure during handover, and receives from the serving BS a status information response message containing available interval and unavailable interval reset information and link disconnection time reset information for extending the link disconnection time. So, the present invention minimizes or prevents a handover delay or extend a link disconnection time with the serving BS, thereby allowing a terminal to receive a continuous service even during the handover procedure.

    摘要: The present invention relates to a method and apparatus for transmitting and receiving data in a multi-carrier communications system. The data transmission/receiving method uses multiple carriers including a primary carrier that is capable of transmitting and receiving data traffic and PHY/MAC control information between a terminal and a base station and at least one secondary carrier that transmits and receives down-link data traffic between the terminal and the base station. The method comprises: generating an MPDU (MAC Protocol Data Unit) to be sent to a PHY (Physical) layer in an MAC (Medium Access Control) layer; performing channel-coding and modulation on the MPDU to generate a modulated symbol sequence in the PHY layer; segmenting the modulated symbol sequence into multiple symbol sequences; and allocating the multiple segmented symbol sequences to multiple carriers, respectively, to perform IFFT (Inverse Fast Fourier Transform) and transmit to a terminal, wherein control information on the multiple carriers is allocated to a control channel region of the primary carrier and transmitted via the primary carrier.
