Full-Duplex Communications System
First Claim
1. A method of full-duplex cellular communications, the method comprising:
- a) receiving at a base station a first signal transmitted by a first cellular device using a cellular uplink frequency in a cellular frequency band;
b) transmitting a second signal 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; and
c) transmitting a third signal 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.

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.

9. A full-duplex cellular base station comprising:
-
a) a receiver coupled to an antenna and configured to receive a first signal transmitted by a first cellular device using a cellular uplink frequency in a cellular frequency band; and b) a transmitter coupled to the antenna and configured to transmit a second signal from the base station to the first cellular device using a downlink frequency in the cellular frequency band simultaneously with the receiving the first signal transmitted by the first cellular device, and configured to transmit a third signal 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
