A method for operating a communications controller adapted for full duplex operation, the method comprising: receiving, by the communications controller, a measurement report from a user equipment served by the communications controller, the measurement report including a first power margin between a current transmit power and a transmit power break point and a second power margin between the current transmit power and a maximum transmit power capable of supporting FD operation; performing, by the communications controller, FD link adaptation in accordance with the first power margin and the second power margin to adjust one or more FD configuration parameters of a link between the communications controller and the user equipment, wherein the link includes a downlink channel and an uplink channel; and instructing, by the communications controller, the user equipment to communicate over the link in accordance with the one or more FD configuration parameters; wherein the transmit power break point comprises a first estimated uplink transmit power level wherein an actual uplink transmit power level greater than the transmit power break point raises a self-interference noise floor of a receiver of the user equipment to be approximately equal to or greater than a non-interference noise floor of the receiver, wherein the self-interference noise floor of the receiver of the user equipment is approximately equal to the non-interference noise floor of the receiver when the self-interference noise floor of the receiver of the user equipment is within 3 to 6 dBs of the non-interference noise floor of the receiver; wherein the maximum transmit power capable of supporting FD operation comprises a second estimated uplink transmit power level wherein an actual uplink transmit power level greater than the maximum transmit power capable of supporting FD operation raises a self-interference noise floor of a receiver of the user equipment above a maximum capable of supporting FD operation at a lowest modulation and coding scheme level. receiving, by the communications controller, a measurement report from a user equipment served by the communications controller, the measurement report including a first power margin between a current transmit power and a transmit power break point and a second power margin between the current transmit power and a maximum transmit power capable of supporting FD operation; performing, by the communications controller, FD link adaptation in accordance with the first power margin and the second power margin to adjust one or more FD configuration parameters of a link between the communications controller and the user equipment, wherein the link includes a downlink channel and an uplink channel; and instructing, by the communications controller, the user equipment to communicate over the link in accordance with the one or more FD configuration parameters; wherein the transmit power break point comprises a first estimated uplink transmit power level wherein an actual uplink transmit power level greater than the transmit power break point raises a self-interference noise floor of a receiver of the user equipment to be approximately equal to or greater than a non-interference noise floor of the receiver, wherein the self-interference noise floor of the receiver of the user equipment is approximately equal to the non-interference noise floor of the receiver when the self-interference noise floor of the receiver of the user equipment is within 3 to 6 dBs of the non-interference noise floor of the receiver; wherein the maximum transmit power capable of supporting FD operation comprises a second estimated uplink transmit power level wherein an actual uplink transmit power level greater than the maximum transmit power capable of supporting FD operation raises a self-interference noise floor of a receiver of the user equipment above a maximum capable of supporting FD operation at a lowest modulation and coding scheme level.
