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.

A method for transmitting and receiving a broadcast channel is disclosed. A wireless access system, a method for effectively transmitting and receiving a broadcast channel, a variety of superframe structures, and a super frame header structure are disclosed. A method for effectively receiving a broadcast channel includes receiving, by a mobile station (MS), a first broadcast channel including first information about a modulation and coding scheme (MCS) applied to a second broadcast channel, and receiving the second broadcast channel using the first information. The first broadcast channel is transmitted using a fixed modulation and coding scheme (MCS) value, and the second broadcast channel is transmitted using a variable modulation and coding scheme (MCS) value.

A method and apparatus for transmitting a paging message in a wireless communication system is provided. A base station receives a paging announcement from a paging controller. The paging announcement includes a machine-to-machine (M2M) group identity (ID) allocated by a first network entity. The base station transmits the paging message to an M2M device. The paging message includes a M2M zone ID of the first M2M zone, managed by the first network entity, allocated by the first network entity or a network entity ID of the first network entity. An M2M group ID allocated to the M2M device by a second network entity is the same as the M2M group ID included in the paging announcement.

A method and device for performing wireless communication ranging are provided. A machine-to-machine (M2M) device receives a paging message from a base station, transmits a bandwidth request (BR) preamble sequence to the base station, receives a first UL grant to allocate an uplink (UL) resource for the transmission of a BR header, transmits the BR header including a ranging request indication parameter to the base station through a UL resource allocated by the first UL grant, receives a second UL grant to allocated a UL resource for transmission of a ranging request message from the bases station, and transmits the ranging request message to the base station through a UL resource allocated by the second UL grant.
摘要:
A method for paging in a wireless access system is disclosed. A method for efficiently paging a mobile station of an idle mode comprises allocating an identifier of a large paging group and an identifier of a specific one of small paging groups included in the large paging group to a broadcast channel region and transmitting a header including the broadcast channel region to the terminal. Accordingly, the present invention enables efficient paging.
摘要:
A method of allocating a paging carrier in a multi-carrier environment is disclosed. The method of allocating the paging carrier includes receiving a first message including first allocation information of the paging carrier, transmitting a second message for requesting entry into an idle mode to a base station; and receiving a third message including second allocation information of a changed paging carrier from the base station. At this time, the paging carrier includes a paging channel out of multiple carriers including one or more carriers.
摘要:
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.
摘要:
A method and device for performing a dedicated ranging for Machine To Machine (M2M) communication is provided. A M2M device receives a paging message indicating a dedicated ranging channel allocation from a base station. The dedicated ranging channel allocation is valid within a dedicated channel allocation timer.
摘要:
A broadband wireless access system and, more particularly, a method for a mobile station and a base station to perform an efficient ranging procedure considering a ranging purpose and a device for performing the same are disclosed herein. A method of a mobile station for performing ranging in a broadband wireless access system, the method includes the steps of transmitting a first ranging preamble code for requesting ranging to a base station through a first ranging opportunity of a first frame, and, when a first message is received from the base station before a timer indicating a limited time point is expired, wherein the first message including a response to the first ranging preamble code is transmitted during the limited time point, determining whether or not the ranging request is successfully made by using the first message.
摘要:
A method for operating in an idle mode and a machine-to-machine (M2M) apparatus are provided. The M2M apparatus receives a deregistration-response (DREG-RSP) message from a base station, and the M2M apparatus in the idle mode monitors a paging advertisement (PAG-ADV) message from the base station. Comprised is a fixed M2M deregistration identifier (FMDID), and the FMDID is a 16-bit identifier for identifying the M2M apparatus in a region of the base station.
