Abstract
A user equipment (UE) is provided that detunes a receive antenna while a transmit antenna transmits. To determine the detuning, the UE first transmits a signal through the transmit antenna while the receive antenna is sequentially coupled through known loads. At each load, the UE determines an input reflection coefficient for a transmit path to the transmit antenna. Based upon the known loads and the corresponding input reflection coefficients, the UE determines a load to couple to the receive antenna to perform the detuning.
