A method for transmitting a Medium Access Control (MAC) control message for an M2M device and an apparatus for supporting the same are disclosed herein. According to an exemplary embodiment, a method for transmitting a MAC control message includes the steps of receiving a broadcast assignment map information element (BA A-MAP IE) including a function index field and broadcast assignment information for the M2M device, and wherein the broadcast assignment information indicates a resource region to which the MAC control message is being transmitted, and, when a cyclic redundancy check (CRC) bit masked to the BA A-MAP IE indicates that the BA A-MAP IE is for a M2M broadcast assignment, receiving the MAC control message through the resource region, which is indicated by the broadcast assignment information.

Disclosed is a method for allocating a ranging channel in a wireless communication system that supports machine to machine communication, and to a base station for same. More particularly, the method comprises the steps of: transmitting a message including a dedicated connection identifier (CID) dedicatedly allocated to a device that supports machine to machine communication; allocating a dedicated ranging area for transmission of a ranging request message to the device that supports machine to machine communication; and transmitting an uplink map (UL-MAP) message including information on the dedicated CID and the dedicated ranging area to the device that supports machine to machine communication.

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.

The present invention provides a variety of methods for an M2M terminal reporting a power outage when an abnormal power outage occurs, and apparatuses for supporting same. A method for performing a random access procedure for reporting the abnormal power outage in the wireless access system supporting an M2M environment, according to one embodiment of the present invention, comprises the steps of: an M2M device receiving a message comprising an abnormal power outage ranging backoff starting parameter and an abnormal power outage ranging backoff ending parameter, which are used for reporting the abnormal power outage; entering an idle mode; and performing the random access procedure for reporting the abnormal power outage using the abnormal power outage ranging backoff starting parameter and/or the abnormal power outage ranging backoff ending parameter, when the abnormal power outage occurs in the idle mode.

Disclosed is a method for transmitting and receiving multicast-data-related information by a machine-to-machine (M2M) device in a wireless communication system, and an apparatus therefor. The method for receiving multicast-data-related information by a machine-to-machine device according to one embodiment of the present invention comprises the following steps: receiving a first message including multicast traffic receiving timer information from a base station; receiving a paging message from the base station; and starting a multicast traffic receiving timer from the point in time indicated by the paging message or from the point in time of receiving the paging message, in accordance with the first message and the paging message. The multicast traffic receiving timer information may include information on a time interval during which the M2M device waits to receive the M2M multicast data in an idle mode.

A method for allocating a HARQ channel identifier (ACID) in a wireless access system includes receiving, from a base station, a first message which includes control information indicating an initial value of a HARQ channel identifier mapped onto a specific service flow, via a dynamic service procedure coupled to a base station; receiving a second message indicating persistent resource allocation from the base station, the second message including information regarding the initial value and number of the ACID used in the persistent resource allocation; comparing the initial value of the ACID with the control information; and allocating the value of the ACID used in the persistent resource allocation to the specific service flow when the control information included in the first message is the same as the initial value of the ACID included in the second message as a result of the comparison.

Disclosed is a method for performing uplink scheduling for an adaptive grant and polling (aGP) service in a broadband wireless access system, the method comprising: transmitting a first message for requesting the switching or changing of a QoS (quality of service) parameter set to a base station; receiving, from the base station, a service specific scheduling control header including adaptation start time information for adapting a new QoS parameter set; and switching or changing to the new QoS parameter set at the checked adaptation start time after checking the adaptation start time information within the received service specific scheduling control.
摘要:
The present description provides a method for allocating a device identifier through an initial network entry process with a base station in a wireless access system. The method comprises a step of transmitting control information, indicating a mobile station supporting Machine to Machine (M2M) communication, to a base station; and receiving a first message, comprising at least one of a first identifier indicative of a group to which devices belong and a second identifier indicative of each of the devices belonging to the group, from the base station.

Disclosed is a method for allocating ACID in a persistent resource allocation including setting an ACID field of a map message to have the same ACID value as ACID value used in a previous persistent allocation upon occurrence of a change, in case where the change occurs in information related to a persistent resource previously allocated to a terminal, sending the map message including the set ACID field to the terminal in the same subframe as a subframe, in which the persistent resource has been allocated prior to the change occurred, and allocating the ACID value of the set ACID field as ACID value for a first data burst after the transmission of the map message.
