Title:
MOBILE DEVICE POSITION CONTROL METHOD AND APPARATUS BASED ON DYNAMIC NOISE OF CHANNEL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/006693
Kind Code:
A1
Abstract:
The present invention provides a mobile device position control method and device based on a dynamic noise of channel information. The method comprises: determining a first change trend of a first secrecy capacity of a communication system on a (n+1)th timeslot relative to a second secrecy capacity of the communication system on a nth timeslot; determining a second change trend of a first eavesdropping capacity of a mobile device on the (n+1)th timeslot relative to a second eavesdropping capacity of the mobile device on the nth timeslot; and adjusting the transmit power for transmitting artificial noise signals by a target end device according to the first change trend, the second change trend, a first path loss, a second path loss, a third path loss and a fourth path loss, and sending feedback information to the mobile device according to the first change trend, so as to control the moving position of the mobile device. In the present invention, the moving position of the mobile device is controlled according to the feedback information, and the secrecy capacity of the communication system is optimized by adaptively adjusting the power of the artificial noise signals, so that secure communication is continuously performed.
