  • Publication number: 20220179981
    Abstract: After a data link between a communication device and a transmitter is established, the transmitter is controlled for determining whether the data link between the transmitter and the communication device is to be disabled when the transmitter is prepared to transmit a first signal to the communication device, or the receiver is prepared to transmit a second signal to the communication device through the transmitter. When the data link is disabled, no signal transmitted from the transmitter is received by the communication device. The first signal and the second signal include feedback control signal information or non-control signal information.
