Abstract
A wireless communication device having a full-duplex architecture is described, the device comprising phase shifters integrated into transmitting chains and receiving chains, respectively, which are connected to basic antennae. Each transmitting/receiving chain is associated with a receiving/transmitting chain so as to form a pair of chains, with a connection circuit arranged between the chains of each pair. The device also includes at least one control module configured to control switching means and to activate/deactivate analogue means and digital means for cancelling interference and all or some of the transmitting/receiving chains so that the device is able to alternate between at least two different modes: a first full-duplex transmitting/receiving mode, and a second mode in which the device is able to reflect one or more transmission beams.
