Embodiment approach

[0191] Under one implementation method, such as Figure 5 It is shown that the size of Txop can be adjusted according to the result of channel detection, and the time length of Txop can be doubled every time when no interference system is found in channel detection. When the channel detection detects the interference system, the Txop time is reduced to a predefined time. As shown below. In another implementation method, the channel detection parameters such as the size of the backoff window can also be adjusted.

[0192] The embodiment of the present invention also provides a channel detection device, which is applied to communication equipment such as base stations and / or terminals of the communication system, Image 6 It is a schematic diagram of the composition structure of the channel detection device 100 provided by an embodiment of the present invention; Image 6 As shown, the device 100 includes: a control module 110, where

[0193] The control module 110 is configured to p...

Abstract

The embodiment of the invention relates to a channel detection method and device, communication equipment and a storage medium. And channel detection is performed on the unlicensed spectrum accordingto the interference condition between the communication systems, or channel resources occupied on the unlicensed spectrum are determined.

Description

Technical field [0001] This application relates to the field of wireless communication technology, but is not limited to the field of wireless communication technology, and in particular to channel detection methods, devices, communication equipment, and storage media. Background technique [0002] The increase in mobile devices and the rapid development of the mobile Internet have brought about the explosive growth of mobile data, which has put forward higher requirements for traffic density, network capacity, user speed, and delay. In order to meet the challenges, the fifth generation (5G , 5 th Generation) mobile communication New Radio (NR, New Radio) has carried out a brand new air interface design for new scenarios and new frequency bands. The shortage of spectrum resources is an increasingly severe reality facing mobile communication networks. Licensed frequency bands, especially high-value low frequency band resources, are not only limited in bandwidth, but are rapidly b...
