Embodiment Construction

[0093] Before introducing the data transmission method provided by the embodiment of the present application in detail, the nouns, implementation environment and application scenarios involved in the embodiment of the present application are firstly introduced.

[0094] First, the nouns involved in the embodiments of the present application are introduced.

[0095] Unlicensed spectrum: It is generally considered to be a shared spectrum, that is, communication equipment in different communication systems can use the unlicensed spectrum as long as they meet the regulatory requirements set by the country or region on the unlicensed spectrum, without the need to apply for a license from the government. There are spectrum authorizations.

[0096] PDCCH: It is a collection of a group of physical resource elements, which can be used to carry DCI (Downlink Control Information, downlink control information), and can also be used to carry COT indication information. According to differ...

Abstract

The present application provides a data transmission method, device, equipment and storage medium, which relate to the technical field of mobile communication. The method includes: detecting the first PDCCH according to the first physical downlink control channel PDCCH detection method; according to the detection result of the first PDCCH and first time information, determining to detect the first End time of PDCCH. Here, the switching of the PDCCH detection mode is no longer solely dependent on the COT indication information, but is determined based on the detection result and the first time information, so as to avoid the failure to enter the reception phase of other channels due to reasons such as the UE missing the COT indication information. problem, increasing the probability of successful data transfer.

Description

[0001] This application is a divisional application of the application dated May 17, 2019, the application number is 2019800058855, and the invention name is "data transmission method, device, equipment and storage medium". technical field [0002] The present application relates to the technical field of mobile communication, and in particular to a data transmission method, device, equipment and storage medium. Background technique [0003] Unlicensed spectrum is a shared spectrum. In order to enable various communication devices to coexist friendly on the unlicensed spectrum, some countries or regions have stipulated the regulatory requirements that need to be met when using the unlicensed spectrum. If it is necessary to follow the principle of listening before using, and in a data transmission, the transmission time cannot exceed the maximum channel occupation time, so as to realize data transmission. [0004] For the access network device, when the channel is seized by m...
