Embodiment Construction

[0033] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] figure 1 It is a flowchart of a method for adjusting an idle channel assessment threshold according to an embodiment of the present invention. Such as figure 1 As shown, the method mainly includes the following processing:

[0035] Step S102: Correcting the PER value;

[0036] Step S104: Adjust the current CCA threshold according to the corrected PER value.

[0037] In related technologies, the CCA threshold cannot be adaptively adjusted according to different environments. use as figure 1 In the method shown, since the adjustment of the CCA threshold is mostly based on the PER value of the MAC layer, the PER value can be corrected according to the change of the environment, and the CCA ...

Abstract

The invention discloses an adjustment method and an adjustment device for a assessment threshold of an idle channel. According to the adjustment method, a packet error rate (PER) value is corrected, and a current clear channel assessment (CCA) threshold value is adjusted according to the corrected PER value. By means of the adjustment method and the adjustment device for the assessment threshold of the idle channel, the CCA threshold value is adjusted dynamically according to the real and valid collision PER value in order to adapt to the changes of different environments, and the effect of improving throughput rate and service quality is achieved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for adjusting an idle channel assessment threshold. Background technique [0002] 802.11 is a wireless local area network standard originally formulated by IEEE. It is mainly used to solve the wireless access of users and user terminals in office LANs and campus networks. Its business is mainly limited to data access, and the rate can only reach 2Mbps. Because it cannot meet people's needs in terms of speed and transmission distance, the IEEE group has successively introduced a series of new standards, from 80.211b and 802.11a to the latest 802.11n and other standards. [0003] With the widespread application of WIFI derived from the 802.11 standard, its network coverage has also evolved from the original simple office or home LAN with relatively few users to the current large-scale carrier-class operation, and the application scenarios have gradually spr...
