摘要:
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.

A frame structure used in a wireless access system and a method for allocating uplink control channels are provided. The method transmits a super-MAP including information regarding a control channel allocation method and control channel allocation information to a receiving end and receives a control signal through an uplink subframe indicated by the control channel allocation information using the control channel allocation method. Thus, the transmitting end can correctly allocate a control channel for each downlink burst.

A method and apparatus for transmitting uplink (UL) data in a wireless communication system is provided. A machine-to-machine (M2M) device receives a deregistration response message including a transmission type and a maximum number of paging cycle during an idle mode entry, waits to receive a paging message for the M2M device to transmit the UL data during a period corresponding to up to (the maximum number of paging cycle×a length of paging cycle), and transmits the UL data.

A method of transmitting data in a wireless communication system is provided. A machine-to-machine (M2M) device transmits a first ranging request message including a M2M short message service (SMS) request indicating that the M2M device has a M2M SMS to transmit, and receives a first ranging response message including a M2M SMS response, a basic connection identifier (CID) and a temporary CID timer. If the M2M SMS request is accepted by a base station, the M2M device transmits a second ranging request message including the M2M SMS based on the basic CID, and receives a second ranging response message including a M2M SMS confirmation indicating whether the reception of the M2M SMS is successful or not by the base station.

A resource allocation method for a HARQ is disclosed. This resource allocation method includes, transmitting an MAP message having specific information indicating whether or not a differential allocation is supported, storing MAP information contained in the MAP message during a predetermined frame, and upon receiving an NACK message during the predetermined frame, transmitting sub-burst information having differential allocation information related to sub-bursts to be retransmitted. If there are a large amount of HARQ traffic, each embodiment of the present invention transmits only differential information on the basis of MAP information of the initial MAP message when HARQ sub-bursts is retransmitted.

The present invention relates to compact header structures of various forms used in wireless access systems as well as a method and apparatus for the transmission and reception of data using such headers. The method for receiving data wherein the mobile terminal uses the Persistent Allocation (PA) mode in one of the embodiments of the present invention comprises the step of receiving a Downlink Persistent Allocation MAP Information Element (DL PA MAP IE) from the base station, which contains information relating to the resource region allocated for persistent allocation in the downlink, and the step of receiving the downlink data containing a Compact Medium access control Header (CMH) via said resource region revealed by said information. At this stage, the CMH can contain an indicator that indicates whether the downlink data contains an extended header, and a length field indicating the length of the data payload.

摘要:
A radio access system, and more particularly, a frame structure and a map structure are provided. A communication method includes transmitting an uplink sub-map to a receiver at a first downlink sub-frame included in a predetermined frame, and receiving data via a data burst indicated by the uplink sub-map at a first uplink sub-frame included in the predetermined frame. If the suggested sub-frame structure is used, it is possible to reduce HARQ ACK delay and HARQ retransmission delay.

A method for transmitting subframe grouping information and a method for decoding subframe-grouped frames are provided. The subframe grouping information transmission method updates a grouping information field of a MAC message, which a serving base station periodically broadcasts to an MS, using subframe grouping information determined by a target base station, and periodically transmits the MAC message to the MS. This method enables provision of a downlink signaling method for supporting variable TTIs of a base station when handover is performed, thereby minimizing service delay of each mobile station and enabling efficient utilization of resources.

A method of allocating a radio resource in a wireless access system is disclosed. The method includes receiving a control message associated with radio resource allocation for transmitting uplink data to the base station, wherein the control message comprises a first persistent uplink allocation information element comprising first resource allocation information associated with a first resource allocation region for transmitting the uplink data of a mobile station and transmitting an acknowledgment (ACK) message from the mobile station to the base station in response to successfully receiving the first persistent uplink allocation information element.
摘要:
A method for allocating resource regions in a wireless access system is provided. This method collectively allocates resources of consecutive frames. Specifically, a message, including allocation information used to collectively and consecutively allocate identical resource regions, is received from a base station and data is transmitted through the allocated resource regions. Unlike the conventional method, a resource region is not allocated in each frame but instead identical resource regions are allocated in multiple frames, thereby reducing MAP overhead in a network.
