  • Patent number: 11889434
    Abstract: A wireless communication includes a control circuit and a receiver (RX) circuit. The control circuit obtains indicator information from another wireless communication system, identifies a transmitter (TX) and receiver (RX) packet delivery scenario as one of a packet overlapping scenario and a packet non-overlapping scenario according to the indicator information, and generates RX gain control information in response to the TX and RX packet delivery scenario. The RX circuit refers to the RX gain control information to set an RX gain used for receiving data.

  • Patent number: 11589376
    Abstract: A multi-radio device includes two or more radio subsystems coupled to a packet traffic arbitration (PTA) module. The PTA module receives a first request for radio communication from a first radio subsystem, where the first request indicates a first usage duration. After granting the first request, the PTA module receives a second request for radio communication from a second radio subsystem. The second request indicates a second usage duration. The PTA module sends a rejection of the second request to the second radio subsystem, where the rejection indicates a remaining time of the first usage duration.

  • 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.
