A method for Co-Reception (Co-Rx) operation of multiple transceiver radios sharing the same antenna and Low Noise Amplifier (LNA) is provided. A first receiver radio of a wireless communication device determines the first gain mode of an LNA based on the first signal indicator. A second receiver radio of the wireless communication device determines the second gain mode of the LNA based on the second signal indicator.
