The antenna receives a current channel information. The current channel information includes an unlicensed channel information of an unlicensed channel. The first transceiver measures an energy information of a current channel according to the unlicensed information. When the first transceiver determines that the energy information is higher than a triggering threshold, the first transceiver accumulates an energy intensity of the current channel and detects an energy feature. The first transceiver determines a spectrum range occupied by a user of the unlicensed channel, avoids transmitting a to-be transmitted data through the spectrum range, and measures an another unlicensed channel, according to an accumulated result of the energy intensity and the energy feature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission method and transmission system for sharing an unlicensed channel in a wireless communications system","description":"A transmission device includes an antenna and a first transceiver.
