  • Publication number: 20230012045
    Abstract: 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. The LNA is shared by the first receiver radio and the second receiver radio and is coupled to an antenna. A Packet Traffic Arbitration (PTA) circuitry of the wireless communication device configures the LNA to operate in the first gain mode or the second gain mode based on the priority levels of the first receiver radio and the second receiver radio.
