Disclosed are a method for receiving multicast data in a wireless communication system and a machine to machine (M2M) device therefor. The method wherein the M2M device receives multicast data in a wireless communication system according to the present invention includes the steps of: receiving multicast data from a base station; and indicating that the multicast data transmitted from the base station is the last multicast or receiving information including a signal which indicates the end of multicast transmission. The information can be transmitted with or separate from the multicast data, and is piggybacked with the multicast data if the information is transmitted with the multicast data.

Disclosed is a method for performing a carrier switching operation in the perspective of a terminal in a multicarrier system, the method including establishing an enhanced-multicast broadcast service (E-MBS) service connection with a base station for E-MBS service reception, sending an E-MBS report message to the base station in the E-MBS service connected state with the base station, the E-MBS report message including connection information related to E-MBS channels, which the terminal is receiving or E-MBS channels, which the terminal intends to receive, receiving an E-MBS response message from the base station in response to the E-MBS report message, and performing a carrier switching operation for the E-MBS service reception based upon unicast available interval information included in the E-MBS response message.

The present description relates to a method for persistent resource allocation in a wireless access system, comprising the following steps: receiving a first MAP message containing persistent resource allocation information from a base station; transceiving data bursts to/from the base station via the persistent resource domain contained in the persistent resource allocation information; and receiving a second MAP message containing persistent resource de-allocation type information from the base station, wherein said persistent resource de-allocation type information indicates whether a de-allocation of persistently allocated resources is a persistent de-allocation or a temporary de-allocation.

As an embodiment of the present invention, a method for supporting a HARQ operation of M2M devices using a HARQ Channel Identifier (ACID) in a wireless access system includes transmitting, at a base station, a second UL A-MAP IE to M2M devices sharing a station identifier (STID) in a subframe in which a second M2M device is to retransmit a UL burst, wherein the second UL A-MAP IE includes resource allocation information for allocating a resource region to a first M2M device and includes a second ACID, receiving the UL burst retransmitted using a first ACID from the second M2M device in the subframe, and receiving a new UL burst transmitted using the second ACID from the first M2M device in the subframe, wherein the first and second M2M devices share the STID, and the first and second ACIDs are different from each other.

A method for transmitting Machine to Machine (M2M) ranging information in a wireless communication system is disclosed. The method includes transmitting an M2M ranging allocation UL MAP extended Information Element (IE) including M2M ranging region information. When the M2M ranging allocation UL MAP extended IE is transmitted, an UL MAP IE with the same region as the M2M ranging allocation UL MAP extended IE is transmitted and an Uplink Interval Usage Code of the UL MAP IE is 12.

A method for transmitting Machine to Machine (M2M) ranging information in a wireless communication system is disclosed. The method includes transmitting an Uplink Channel Descriptor (UCD) including an M2M ranging region Type/Length/Value (TLV). When the UCD is transmitted, a ranging region TLV identifying the same region as the M2M ranging region TLV is included in the UCD.
摘要:
The present invention is a method for operating terminals in a broadband wireless communication system in which a persistent allocation technique is employed, comprising the steps of: receiving a persistent resource allocation message from a base station; determining whether or not the persistent resource allocation message includes frame position information related to a second persistent resource allocation; deciding a frame position for allocating a persistent resource based on a persistent allocation period and the frame position information included in the persistent resource allocation message, when it is determined that the frame position information related to the second persistent resource allocation is included; and receiving a data packet using the persistently allocated resource at the decided frame position.

Disclosed is a method for transmitting and receiving idle-mode parameter update information and an apparatus therefor. A machine-to-machine (M2M) device for receiving idle-mode parameter update information in a wireless communication system comprises: a receiver for receiving, from a base station, a paging message including an M2M group identifier (ID) field indicating an M2M group ID and an action code field indicating an idle-mode parameter update; and a processor that decodes the action code field when said M2M group ID corresponds to the M2M group ID of the processor, to thereby acquire information which indicates that said paging message is a message relating to the idle mode parameter update. The paging message may further include an updated M2M group ID field indicating an updated M2M group ID, and the processor may decode the updated M2M group ID field to thereby acquire updated M2M group ID information.

The present invention relates to a method in which an M2M device transceives data to/from a base station in a wireless access system. The method comprises: a step of receiving, from the base station, a first message containing an available interval or an M2M device ID shared among M2M devices, and an M2M device ID use period in which said available interval periodically repeats; and a step of transceiving data to/from the base station using the M2M device ID in the available interval.

Disclosed is a method for receiving a paging message by a mobile station in an idle mode including an unavailable interval (UAI) and an available interval (AI) in a wireless access system, including: checking whether or not system information has been changed during the UAI; when the system information has been changed during the UAI, updating the system information during the UAI; and receiving the paging message from a base station (BS) during the AI.
