Title:
FULL-DUPLEX COMMUNICATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/220927
Kind Code:
A1
Abstract:
A full-duplex communication device and method, for use in eliminating interference in multi-antenna application scenarios. The device comprises one or more full-duplex units. The full-duplex unit comprises a power division module, transceiver antennas, cancellation antennas, and a combination module. The power division module is configured to divide a signal to be sent into a first signal and a second signal. The transceiver antenna is configured to send the first signal by means of a first sending port and to receive a third signal by means of a first receiving port, wherein the third signal comprises an interference signal and a signal sent by other communication devices. The cancellation antenna is configured to send the second signal by means of a second sending port and to receive a cancellation signal by means of a second receiving port. The combination module is configured to perform differential combination on the third signal and the cancellation signal to output an interference-cancelled signal. A scattering parameter matrix of all transceiver antennas is the same as that of all cancellation antennas.
