Abstract

The method includes following steps: in both direction of up stream and down stream, the base station translates the QoS parameters of all connections relating to the terminal applying bandwidth into the reference variable of allocating bandwidth to allocate and dispatch total bandwidth for the terminals; in down stream direction, the base station makes reallocation for connections according to IEEE802.16 standard in term of acquired total bandwidth; in up stream direction, all terminals obtain the bandwidth allocation information based on taking base station as terminal, and make reallocation in their own bandwidth for connections.

Description

technical field

[0001] The present invention relates to a bandwidth allocation method of a Broadband Wireless Access (BWA, Broadband Wireless Access) system, in particular to a modulation and demodulation method using OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) in compliance with IEEE802.16 A bandwidth allocation method of a standard broadband wireless access system. Background technique

[0002] In recent years, due to the lack of a unified BWA standard, each manufacturer has its own way, making the existing BWA systems on the market unable to communicate with each other, thus greatly limiting the development space of BWA products. Therefore, the 802.16 protocol launched by the IEEE (Institute of Electrical and Electronics Engineers) will end the chaotic situation of the BWA standard group and provide a good opportunity for the development of the BWA system.

[0003] In the IEEE802.16 protocol, a concept of bandwidth alloca...
