A wireless communication system using multiple channels is provided. An apparatus includes an allocator for, when bursts are allocated to an Accessing Terminal (AT) which utilizes a plurality of channels at the same time, allocating the same amount of the bursts to each channel in use; a generator for, when a map message to be transmitted in a primary channel of the AT is generated, generating the map message which comprises allocation information of the bursts allocated to the AT; and a transmitter for transmitting the map message in the primary channel of the AT.

The present application claims the benefit under 35 U.S.C. §119(a) to a Korean patent application filed in the Korean Intellectual Property Office on Feb. 18, 2008 and assigned Serial No. 10-2008-0014359, the entire disclosure of which is hereby incorporated by reference.
The present invention relates generally to a broadband wireless communication system. More particularly, the present invention relates to an apparatus and a method for allocating bursts in the broadband wireless communication system.
A fourth generation (4G) communication system, which is a next-generation communication system, aims to provide users with services of various Quality of Service (QoS) levels at a data rate of about 100 Mbps. Particularly, present-day 4G communication systems are advancing in order to guarantee mobility and QoS and to support high-speed services in Broadband Wireless Access (BWA) communication systems such as wireless local area network systems and wireless metropolitan area network systems. Representative examples include the Institute of Electrical and Electronics Engineers (IEEE) 802.16 communication systems. The IEEE 802.16 communication systems adopt Orthogonal Frequency Division Multiplexing (OFDM)/Orthogonal Frequency Division Multiple Access (OFDMA) schemes to support a broadband transmission network in physical channels.
For a more complete understanding of the present disclosure and its advantages, reference is now made to the following description taken in conjunction with the accompanying drawings, in which like reference numerals represent like parts:
FIG. 1 illustrates a distribution of two-dimensional bursts allocated when consecutive channels are used in a broadband wireless communication system according to an exemplary embodiment of the present invention;
FIG. 2 illustrates a distribution of two-dimensional bursts allocated when nonconsecutive channels are used in the broadband wireless communication system according to an exemplary embodiment of the present invention;
Throughout the drawings, like reference numerals will be understood to refer to like parts, components and structures.
FIGS. 1 through 8, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication system.
Exemplary embodiments of the present invention provide a burst allocation technique in a broadband wireless communication system. Although an Orthogonal Frequency Division Multiplexing (OFDM)/Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system is illustrated by way of example, the present invention is applicable to other wireless communication systems.
