Embodiment Construction

[0027] Matters defined in the specification, such as detailed structures and constituent elements, are provided to assist in a comprehensive understanding of the exemplary embodiments of the invention. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0028] Embodiments of the present invention provide an apparatus and method for allocating IDcells in a broadband wireless communication system.

[0029] The IDcell allocation described here is only an exemplary application. Thus, the present invention also applies to assigning other sector identification parameters, such as DL_PermBase and UL_PermBase.

[0030] In order to calculate the cost of using the same IDcell in adjacent sectors, inter-sector proximity must b...

Abstract

The present invention provides an apparatus and method for allocating IDcells in a wireless communication system, wherein an initial IDcell allocation is performed by allocating an entire sector to elements of an N×M IDcell matrix, in which each IDcell with the highest Proximity sector pairs, the IDcell with the highest proximity sector pair among the selected sector pairs is determined as the target IDcell, and one sector of the sector pair with the highest proximity target IDcell is selected as the target sector , from the sectors to which each other IDcell is allocated except the target IDcell, select a predetermined number of sectors for each other IDcell, and combine the IDcells of the target sector with the selected sectors that meet the first condition The IDcell of the sector is exchanged.

Description

[0001] This application claims the benefit of Korean Patent Application Serial No. 2006-0099841 filed on October 13, 2006 at the Korean Intellectual Property Office under 35 U.S.C. § 119(a), the entire disclosure of which is incorporated herein by reference Reference. technical field [0002] The present invention relates to allocation of ID cells, in particular to a device and method for allocating ID cells in a broadband wireless communication system. Background technique [0003] The Institute of Electrical and Electronics Engineers (IEEE) 802.16e communication system is basically a cellular system. Since the communication system uses a frequency reuse factor of 1, the same frequency can be used in adjacent cells. Therefore, a mobile station (MS) must be able to distinguish its traffic sector from neighboring sectors in a sector using the same frequency. To do this, each sector transmits its specific pseudorandom noise (PN) code, called a preamble, in the first symbol o...
