摘要:
The present invention relates to a broadband wireless access system; and more specifically to a method and apparatus for performing an efficient ranging procedure by mobile station and a base station, by distinguishing the dedicated ranging from the contention-based random access. A method for performing ranging with a mobile station in a broadband wireless access system according to one embodiment of the present invention comprises: transmitting a first ranging code for requesting ranging to a base station through a first ranging opportunity of a first frame; and receiving a first message including a response to the first ranging code, wherein if the first ranging code is a dedicated ranging code and the response to the first ranging code is “continue”, the first message may further include at least one of a dedicated flag field, a second ranging code, and the information on the second ranging opportunity.

A method of efficiently allocating a resource to a mobile station to support a real time service in a radio access system is provided. The method includes grouping one or more mobile stations and allocating a group resource area for transmitting bandwidth request information for transmitting real time service data of the grouped one or more mobile stations, and allocating respective individual resource areas of the one or more mobile stations included in the group resource area. Since the method of grouping the mobile service and efficiently allocating an uplink resource are provided, it is possible to reduce message overhead and efficiently use the resource.

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.

摘要:
A method for requesting a bandwidth by a message having a variable format is disclosed. The method includes determining a bandwidth request type according to a size of an uplink bandwidth requested by a mobile station, generating a bandwidth request message having a header format according to the determined bandwidth request type, and transmitting the bandwidth request message to a base station. The determined bandwidth request type is one of a bandwidth request per connection, a bandwidth request per Quality of Service (QoS), and a bandwidth request per mobile station.
摘要:
The present invention relates to a method for transmitting service flow information in a wireless communication system. The method for transmitting service flow information in a wireless communication system according to one aspect of the present invention comprises the step of enabling a terminal to transmit, to a base station and through the service flow to be generated or modified during a service flow generating or modifying process, an indicator for indicating whether or not uplink data to be transmitted exists.

A method for transmitting and updating system information in a system that supports a legacy mobile station is disclosed. A method for transmitting system information according to one embodiment of the present invention comprises transmitting a super-map through a new zone of a super-frame, the super-map including channel description transmission control information indicating a channel descriptor of a legacy zone; and transmitting the channel descriptor and a map message through the legacy zone, the map message indicating the channel descriptor.
摘要:
A method for allocating resource regions in a wireless access system. This method collectively allocates resources in non-consecutive frames. Specifically, a message, including allocation information used to collectively and non-consecutively allocate identical resource regions, is received from a base station and data is transmitted or received through the allocated resource regions. Since identical resource regions are collectively allocated in multiple frames, it is possible to reduce both the number of transmissions of a MAP message and MAP overhead in a network.
摘要:
A method and device for allocating resource regions in a broadband wireless access system. The method includes receiving a message from a base station by a mobile terminal. The message includes allocation information used to collectively and consecutively allocate identical resource regions of consecutive frames. The identical resource regions include identical Orthogonal Frequency-Division Multiple Access (OFDMA) symbols and identical subchannels within each of the identical resource regions. The identical OFDMA symbols are a subset of a total number of OFDMA symbols within each of the identical resource regions. The identical subchannels are a subset of a total number of subchannels within each of the identical resource regions. The method also includes transmitting or receiving data by the mobile terminal through the allocated identical resource regions.
