Abstract
A method of full-duplex cellular communications includes receiving a first signal transmitted by a first cellular device at a base station using a cellular uplink frequency in a cellular frequency band. A second signal is transmitted from the base station to the first cellular device using a cellular downlink frequency in the cellular frequency band simultaneously with the receiving the first signal transmitted by the first cellular device. A third signal is transmitted from the base station to a second cellular device using the cellular uplink frequency in the cellular frequency band simultaneously with the receiving the first signal transmitted by the first cellular device and simultaneously with the transmitting the second signal from the base station to the first cellular device.
