    摘要: A method for performing a handover by a user equipment from a serving base station to a target base station includes transmitting a random access preamble to the target base station, receiving a random access response in response to the random access preamble; after receiving the random access response, transmitting a handover confirm message for indicating completion of the handover between the user equipment and the target base station, and transmitting a packet data sequence number report message indicating packet data received from the serving base station in a process of performing the handover. Repeated transmission of downlink data or uplink data can be avoided during a handover procedure.

    摘要: A method for saving power in a multi-carrier wideband wireless access system is provided. A method for saving the power of a receiver in a multi-carrier wireless communication system includes acquiring multi-carrier information from a transmitter on a primary carrier, entering one or more secondary carriers satisfying a predetermined power saving mode entry condition out of one or more secondary carriers included in the multi-carrier information into a power saving mode, and receiving data during a listening interval according to the power saving mode on the one or more secondary carriers entering the power saving mode. The multi-carrier information includes at least one of information about a plurality of available carriers, information indicating the primary carrier and the one or more secondary carriers out of the plurality of available carriers, and information about the power saving mode entry condition of the one or more secondary carriers.

    摘要: A method for performing ranging is disclosed. The method for performing ranging in a wireless communication system which simultaneously supports a legacy system and a new system includes a method for additionally allocating a ranging channel to a zone other than a legacy zone and a method for re-using a legacy ranging channel within the legacy zone. When the legacy ranging channel is re-used, ranging codes may be shared by a legacy mobile station and a new system mobile station or may be separated on a ranging code domain. Limited radio resources can be effectively employed by re-using the legacy ranging channel.
