Abstract

The embodiment of the invention discloses an adaptive threshold adjusting method. The method includes the steps of acquiring the reception information of adata packet; adjusting a threshold according to the adjustment method corresponding to the reception information of the data packet, and taking the adjusted threshold as the current threshold. The invention also discloses an adaptive threshold adjusting device. The adoption of the invention can implement adaptive threshold adjustment, can ensure the control operation implemented on the basis of the threshold to adapt to the requirement of the fast-changing wireless circumstance, and can improve the communication quality.

Description

technical field [0001] The invention relates to control technology, in particular to a threshold value self-adaptive adjustment method and device. Background technique [0002] The IEEE 802.16e protocol makes it possible to use a terminal to enjoy wireless broadband access services at any time and anywhere. The Worldwide Interoperability for Microwave Access Forum (WIMAX, Worldwide Interoperability for Microwave Access Forum) system based on the IEEE 802.16e protocol appears. become a hot spot of concern. Key technologies such as hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request) and adaptive modulation and coding (AMC, Adaptive Modulation and Coding), etc., enable the WIMAX system to further improve the main performance such as speed, throughput and capacity. [0003] In the WIMAX system, control operations such as AMC control and power control need to involve the use of threshold values. Taking AMC control as an example, in the downlink direction, th...
