A method for sending and receiving multi-carrier information in a communication system supporting a multi-carrier includes sending by a base station system information to the terminal via a broadcast message, the system information regarding multi-carriers that the base station is able to support; receiving a unicast message from the terminal, the unicast message including information related to carriers that the terminal is able to support or prefers in the multi-carrier list included in the system information; and sending multi-carrier allocation information including a primary carrier and a second carrier that the terminal will use, to the terminal via a unicast message.

Method and apparatus for sending and receiving multi-carrier information in multi-carrier communication system

A method for operating a plurality of carriers by a first base station in a wireless communication system supporting a primary carrier and at least one secondary carrier is discussed. The method includes transmitting, to a user equipment through the primary carrier, control information for exchanging traffic via the at least one secondary carrier with the user equipment; transmitting, to the user equipment, the traffic through the secondary carrier, wherein the user equipment is configured to receive the traffic based on the control information; and transmitting, to the user equipment, a message for a procedure of an entrance to a second base station. Further, the primary carrier is changed on the procedure of the entrance based on the message.

A method for operating a plurality of carriers by a user equipment in a wireless communication system supporting a primary carrier and at least one secondary carrier, the method includes transmitting, to a base station, carrier capability information; receiving, from the base station, carrier configuration information, the carrier configuration information including an index of the at least one secondary carrier configured for the user equipment, the carrier configuration information being based upon the carrier capability information of the user equipment, the primary carrier being configured as a carrier for performing an initial network entry procedure; receiving, from the base station, a control channel including information regarding multi-carrier operation through the primary carrier; and transmitting, to the base station, traffic through one of the at least one secondary carrier based on the information regarding multi-carrier operation.

A method for configuring system information, a method for transmitting system information, and a method for transmitting resource ratio information are disclosed. A method for receiving system information elements includes receiving a first message including a fixed-size system information element from a base station, and receiving a second message including an variable-size system information element from the base station.

Method for transmitting and receiving system information elements in a wireless access system

A method for efficiently performing an initial access in an MS in a multi-carrier broadband wireless access system is disclosed. The method includes scanning a plurality of carriers supported by a BS, and selecting one of the scanned carriers as a first carrier and receiving an SFH of the first carrier. The SFH of the first carrier includes at least one of a field indicating load status of the first carrier and recommended network entry carrier information including information about a second carrier in good load status.

Method for efficiently performing initial access in a multi-carrier broadband wireless access system

Provided are a method and device for ranging in a wireless communication system. A machine-to-machine (M2M) device receives an advanced air interface-system configuration descriptor (AAI-SCD) message including information on a dedicated ranging channel for the M2M device and an M2M parameter change count from a base station, and attempts ranging through the dedicated ranging channel to the base station. At this point, the M2M parameter change count orders information on the dedicated ranging channel in the AAI-SCD message to change.

Method and device for ranging in a wireless communication system

Provided are a method and an apparatus for monitoring a paging message in machine-to-machine (M2M) communications. An M2M device receives a paging setup for initiating an idle mode from a base station. The paging setup includes information indicating a paging cycle, a first paging offset, and a second paging offset. In the idle mode, the M2M device monitors the transmission of a paging message at the first paging offset of the paging cycle. If the paging message is not received at the first paging offset, the M2M device monitors the transmission of the paging message at the second paging offset of the paging cycle.

Method and apparatus for monitoring a paging message in M2M communications

Provided are a method and device for M2M (Machine To Machine) communication. A M2M device receives a DSA (dynamic service addition) message from a base station, and the DSA message includes an MGID (M2M Group identifier) related to an M2M multicast service. The M2M device receives a paging advertisement (PAG-ADV) message from the base station in an idle mode, and the PAG-ADV message includes the MGID and an action code directing a location update performance. The M2M device transmits a ranging request (RNG-REQ) from the base station to perform a location update.

Method and device for M2M communication

A method for configuring system information, a method for transmitting system information, and a method for transmitting resource ratio information are disclosed. A method for receiving system information elements includes receiving a find message including a fixed-size system information element from a base station, and receiving a second message including an variable-size system information element from the base station.

An apparatus and methods for communicating in a wireless access system using a medium access control protocol data unit (MAC PDU), the method including receiving, by a mobile station (MS) from a base station (BS), a dynamic service addition request (AAI_DSA-REQ) message requesting to create a service flow, the AAI_DSA-REQ message including a first MAC header type parameter indicating a type of a MAC header included in the MAC PDU of the service flow and a flow identifier (FID) identifying a connection associated with the service flow; transmitting, by the MS to the BS, a dynamic service addition response (AAI_DSA-RSP) message in response to the AAI_DSA-REQ message, the AAI_DSA-RSP message including a second MAC header type parameter indicating the type of a MAC header included in the MAC PDU of the service flow; and communicating with the BS using the MAC PDU.

Apparatus and method for transmitting a MAC PDU based on MAC header type information

The present invention relates to a broadband wireless access system, and more particularly to a method for efficiently communicating scheduling information about a broadcasting message to a terminal. The method for transmitting the broadcasting message in the broadband wireless access system comprises the steps of: transmitting a first map including scheduling information for at least one broadcasting message transmitted within a predetermined transmission unit to a terminal; and broadcasting the message through a resource region indicated by the scheduling information. In the method, it is desirable that the first map is an extended map of a second map including non-user specific control information.

Method for efficiently transmitting broadcasting message in broadband wireless access system

A method and device for operating in an idle mode for Machine To Machine (M2M) communication are provided. A M2M device receives a paging message from a base station. The paging message includes a M2M group identifier that identifies a M2M group to which the M2M device belongs. The M2M device monitors an uplink resource allocation beginning from an offset during a monitoring duration.
