LNA gain adaption based on received signal strength of signals conforming to different communication protocols

A method, on an apparatus, the method comprising:

• conveying first signals that conform to a first communication protocol between i) a first communication module configured to operate according to the first communication protocol and ii) one or more antennas, wherein the first signals are conveyed via a first radio frequency (RF) path dedicated for the first communication module;
• receiving, at a low noise amplifier, i) a first receive signal that conforms to the first communication protocol, and ii) a second receive signal that conforms to a second communication protocol, wherein the low noise amplifier is coupled to i) the one or more antennas, ii) a second RF path dedicated for the first communication module, and iii) a third RF path dedicated for the second communication module;
• determining a first signal strength indicator corresponding to a signal strength of the first receive signal that conforms to the first communication protocol;
• determining a second signal strength indicator corresponding to a signal strength of the second receive signal that conforms to the second communication protocol;
• controlling a gain of the low noise amplifier based on at least the first signal strength indicator and the second signal strength indicator;
• and
• controlling which of i) the first RF path, ii) the second RF path, and iii) the third RF path is utilized based on at least one of i) a transmit or receive state corresponding to the first communication protocol, and ii) an awake state corresponding to the second communication protocol.

A tangible, non-transitory computer readable medium storing machine readable instructions that, when executed by a processor, cause the processor to:

• determine a first signal strength indicator corresponding to a signal strength of a first signal that conforms to a first communication protocol, the first signal received at a radio frequency front end device configured to communicatively couple a plurality of communication modules to at least one antenna, wherein the plurality of communication modules comprises i) a first communication module configured to operate according to the first communication protocol and ii) a second communication module configured to operate according to a second communication protocol, and wherein the radio frequency front end comprises
