FULL-DUPLEX WIRELESS COMMUNICATION METHOD, ANTENNA DEVICE AND FULL-DUPLEX WIRELESS COMMUNICATION SYSTEM
First Claim
1. A full-duplex wireless communication method, comprising steps of:
- within a training period, acquiring a relevant parameter for cancelling a self-interference signal from an antenna itself as a first estimated value, and a relevant parameter for cancelling a cross-interference signal between the antenna and the other antenna as a second estimated value; and
within a data transmission period, receiving and transmitting signals simultaneously by the antenna using an identical frequency, cancelling the self-interference signal from the antenna itself in accordance with the first estimated value, and cancelling the cross-interference signal between the antenna and the other antenna in accordance with the second estimated value.

10. An antenna device, comprising:
-
a parameter estimation module configured to, within a training period, acquire a relevant parameter for cancelling a self-interference signal from an antenna itself as a first estimated value, and a relevant parameter for cancelling a cross-interference signal between the antenna and the other antenna as a second estimated value; and an interference cancellation module configured to, within a data transmission period, cancel the self-interference signal from the antenna itself in accordance with the first estimated value and cancel the cross-interference signal between the antenna and the other antenna in accordance with the second estimated value when signals are received and transmitted simultaneously by the antenna using an identical frequency. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
