METHOD FOR IMPROVING PACKET TRANSMISSION PERFORMANCE OF SECOND USER IN COGNITIVE WIRELESS NETWORK, AND DEVICE THEREFOR

WIPO Patent Application WO/2020/022592

A1

The present invention relates to a method for improving packet transmission performance of a second user in a cognitive wireless network, and a device therefor. A method for improving packet transmission performance of a second user in a cognitive wireless network according to the present invention, which is a method for improving packet transmission performance of a second user device in a cognitive wireless network, comprises the steps of: the second user device determining a state of channel occupancy by a first user device through spectrum sensing; the second user device selecting an operation mode from a backscatter mode and an energy harvesting mode on the basis of an energy level when the second user device accesses a channel occupied by the first user device; and the second user device operating according to the selected operation mode.
