Disclosed is a method for determining whether a machine-to-machine group identifier (MGID) for identifying a multicast service flow is supported in a wireless access system that supports machine-to-machine (M2M) communication, wherein the multicast service flow is shared by a group of M2M terminals within an M2M group zone that is allocated to the terminals. The method comprises the steps of: receiving from the first base station M2M group zone information of the first base station and neighboring base stations; receiving from the second base station system information of the second base station; and determining whether the MGID that is received from the first base station is supported by the second base station by comparing the system information of the second base station and the M2M group zone information on the neighboring base stations.

Provided is a method for machine to machine (M2M) communication. An M2M device acquires an M2M group identification (MGID) and an M2M zone identification. The M2M device checks whether or not the M2M device has escaped from the M2M group zone. If the M2M device has escaped from the M2M group zone, the M2M device transmits, to a base station, an update request message which requests that the M2M group identifier be updated. The M2M device receives, from the base station, a response message as a response to the update request message.

Provided are a method and an apparatus for confirming the validity of a candidate cooperative device list for client cooperation in a wireless communication system. A base station searches for at least one candidate cooperation device for a source device, then an effective period timer, for an effective time command list for a list of candidate cooperation devices for a source device, is initiated, and a determination is made as to whether the list of candidate cooperation devices is valid. The base station and the source device are connected through a first system, and the base station and one recommended candidate cooperation device selected from the list of candidate cooperation devices are connected through a second system.

Provided are a method and a device for transmitting data through client cooperation in a wireless communication system. A cooperative device of the client cooperation receives uplink (UL) data from a source device through a frame of a first system, and if the UL data is the data to be transmitted to a base station of the second system, transmits the UL data to the second system. In addition, when receiving downlink (DL) data from the base station of the second system, and the DL data is data to be transmitted to the source device, the DL data is transmitted to the source device through the frame of the first system.

The present invention relates to a method and a device for managing carriers allocated to a terminal in a broadband wireless access system that supports multi-carrier. A method for managing carriers by a terminal in a broadband wireless access system supporting multi-carrier includes transmitting, to a base station, activation requests information for requesting the activation of at least one second carrier allocated from the base station through a first carrier according to the power state of the terminal, receiving, from the base station, a first message that includes activation indication information for indicating the activation of at least one target carrier of the at least one second carrier, and transmitting to the base station a second message which notifies the base station whether the at least one target carrier is ready per activation.

The present invention relates to a broadband wireless communication system, and disclosed are a method and an apparatus for executing a carrier management process in a broadband wireless communication system which supports multi-carrier. According to one embodiment of the present invention, a method for executing carrier management by a terminal in a communication system which supports the multi-carrier comprises the steps of: receiving a signal which indicates control channel allocation for a 1st carrier from a base station; receiving a signal which indicates control channel de-allocation for a 2nd carrier from the base station; activating the 1st carrier if the 1st carrier on which the control channel allocation is indicated is in an inactivate state; and inactivating the 2nd carrier if the 2nd carrier on which the control channel de-allocation is indicates is in an activated state.

The present invention relates to a broadband wireless access system, and more particularly, to a method in which a terminal acquires and updates global carrier configuration information of base stations in a network, and to an apparatus for performing the method. According to one embodiment of the present invention, a method in which a terminal acquires carrier configuration information in a broadband wireless access system that supports multiple carriers comprises the following steps; transmitting a first message containing a change count value of the carrier configuration information acquired by the terminal: receiving, from the base station and in response to the first message, a second message containing the current change count value of the carrier configuration information; and, if the change count value of the first message and the change count value of the second message are different from each other, receiving a third message containing current carrier configuration information and the current change count value from the base station.

The present invention relates to a broadband wireless access system including a relay station, and more particularly to an efficient procedure of Automatic Repeat Request (ARQ) operations in a relay station and an apparatus for performing the same. A method for transmitting data for at least one terminal (AMS) from a base station (ABS) to a relay station (ARS) in the broadband wireless access system according to an embodiment of the present invention comprises the steps of generating second transmission unit data using a plurality of first transmission unit data to which different relay sequence numbers are assigned; and transmitting the second transmission unit data to the relay station. The second transmission unit data can be transmitted through the same tunnel as the first transmission unit data.
摘要:
A method and apparatus of uplink synchronization in a multiple carrier system is provided. After establishing Uplink synchronization for a primary carrier, a secondary carrier based on activation information via the primary carrier is activated. A periodic ranging via the secondary carrier is performed to adjust uplink synchronization for the secondary carrier.
