A method and apparatus for performing a handover in a wireless communication system are disclosed. The method for performing a handover of a user equipment (UE) in a wireless communication system includes measuring a first reception power from a first transmission point and a second reception power from a second transmission point; and determining transmission of a measurement report for the handover to the second transmission point. The transmission of the measurement report is determined using the first reception power, the second reception power, an offset value, and a value related to uplink transmission power of the user equipment (UE).

Disclosed are a method for transceiving data in a wireless access system, and a base station and terminal therefor. More particularly, the present invention relates to a method for transceiving data, and to a base station device for the method, wherein the method comprises the steps of: transmitting, in a single first subframe, a physical downlink control channel (PDCCH) including downlink scheduling information on each terminal; and transmitting, in a plurality of second subframes, a physical downlink shared channel (PDSCH) relevant to said PDCCH to each terminal. The PDCCH supports a carrier aggregation that includes a field indicating said plurality of second subframes in which said PDSCH is transmitted.

The present invention relates to a method for transmitting and receiving synchronization signals in a wireless access system for supporting carrier aggregation/multiple cells (CA) and an apparatus therefor. Specifically, the present invention includes the steps of transmitting a first synchronization signal through an extension carrier which is not operated as a single carrier but is operated as a part of the CA, wherein a transmission area of the first synchronization signal differs from a transmission area of a second synchronization signal which is transmitted through a legacy carrier capable of being operated as the single carrier.
