Abstract: The present invention relates to the field of communications, and provides a link adaptation method and device, so as to determine, according to transmission quality of a signal in a link, to perform antenna alignment and/or frequency adjustment. The method includes: detecting, by a first antenna device, an RSSI of a link between the first antenna device and a second antenna device; when it is determined that the RSSI is greater than or equal to a first RSSI threshold, detecting, by the first antenna device, an SINR of the link; and choosing, by the first antenna device according to the RSSI and the SINR, to perform frequency adjustment and/or antenna alignment with the second antenna device. Embodiments of the present invention are applied to link adaptation.

Abstract: A method for reducing adjacent-channel interference includes: obtaining, by a receiver, a first analog signal from a radio frequency front-end of a transmitter, where the first analog signal is a signal transmitted by the transmitter to the outside, and the signal transmitted by the transmitter to the outside forms a self-interference signal at an antenna of the receiver; performing analog-to-digital conversion on the first analog signal so as to obtain a first digital signal; receiving, by the receiver, a second analog signal, where the second analog signal includes a wanted signal and the self-interference signal; performing analog-to-digital conversion on the second analog signal so as to obtain a second digital signal; and performing digital cancellation on the second digital signal and the first digital signal so as to obtain a wanted digital signal of the second digital signal.

Abstract: A method for generating a wireless virtual network and a wireless network control device are provided. In some feasible embodiments of the present invention, a wireless network control device responds to a wireless virtual network establishment/modification request of a wireless virtual network demander, and configures a base station according to the wireless virtual network establishment/modification request. The wireless network control device receives configuration completion response of the base station, confirms the success of wireless virtual network establishment/modification, and sends a parameter of the wireless virtual network to the wireless virtual network demander. Then, the wireless network control device receives a parameter confirmation message of the wireless virtual network demander, and the wireless virtual network takes effect.
