Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] refer to figure 1 , a method for dividing a broadband wireless access system AMC Zone, comprising the following steps:

[0025] Step 101: Differentiate the types of MSs in the broadband wireless access system to construct AMC MS queues and PUSC MS queues, that is, store them in the AMC MS queues and PUSC MS queues according to the physical attributes of each MS and the allocation method of supported subcarriers queue; this step can be realized through the MS type judgment module during actual operation;

[0026] Step 102: Judging the type of the first MS scheduled in this frame according to the MS scheduling mode, and correspondingly dividing the AMC Zone operation according to the judgment result; in actual operation, the MS scheduling can be realized through the scheduler scheduled by MS, and through The Zone division module realizes the division operation o...

Abstract

The present invention discloses a method for dividing AMC Zone of broadband wireless access system, which comprises the following procedures: 1. differentiating the style of each MS in broadband wireless system to construct AMC MS array and PUSC MS array; and 2. determining the style of a first MS scheduled by an MS scheduling mode, and dividing AMC Zone according to the determined result. The technical plan according to the invention is introduced with a scheduling mode scheduled by MS. The dividing of AMC Zone can be realized without looking through the whole connection and only executing corresponding scheduling according to the physical property of MS at the condition that the scheduling resource can not be obtained beforehand.

Description

technical field [0001] The present invention relates to a Zone (area) division method, in particular to a broadband wireless access system AMC (Adjacent Subcarrier Permutation, adjacent subcarrier allocation) Zone division method. Background technique [0002] At present, broadband wireless communication systems are developing very rapidly. Broadband wireless access technology is considered to be an important means to solve the "last mile" of broadband metropolitan area network construction due to its low investment, quick results, and flexible networking, enabling the realization of information highways. Open to traffic, wherein, the multi-carrier transmission system based on OFDM (Orthogonal Frequency-Division Multiplexing, Orthogonal Frequency-Division Multiplexing) technology has attracted more and more people's attention. [0003] The physical layer of the OFDM system supports sub-channelization, and the actual channel can be divided into several sub-channels. Due to th...
