Patent ID: 8565112

Claim:
A method for concurrently transmitting a Wi-Fi signal and a Bluetooth signal using a single power amplifier coupled to an antenna, the method comprising: requesting transmission of the Wi-Fi signal; determining an expected transmission power level of the Wi-Fi signal; if the Bluetooth signal is currently being transmitted, determining a transmission power level of the Bluetooth signal; retrieving from a look-up table a maximum allowed Wi-Fi power level associated with the determined Bluetooth transmission power level; comparing the maximum allowed Wi-Fi power level with the expected Wi-Fi transmission power level; and selectively transmitting the Wi-Fi signal concurrently with the Bluetooth signal in response to the comparing, wherein the selectively transmitting comprises: determining a Wi-Fi back-off power level based, at least in part, on the maximum allowed Wi-Fi power level and the expected Wi-Fi transmission power level; and reducing a gain of the power amplifier by the Wi-Fi back-off power level and processing the Wi-Fi signal concurrently with the Bluetooth signal in the power amplifier based, at least in part, on a comparison of the Wi-Fi back-off power level and a predetermined value.
