  • Patent number: 11774497
    Abstract: The present invention discloses an isolation circuit having test mechanism. An isolation circuit component performs signal transmission when a signal that a control terminal receives has an enabling state and performs signal isolation when the signal has a disabling state. The test circuit includes a multiplexer and a control circuit. Under a shifting operation state in a test mode, the control circuit controls the multiplexer to select an operation input terminal to receive and output an isolation control signal having the enabling state to the control input terminal. Under a capturing operation state in the test mode, the control circuit controls the multiplexer to select a test input terminal to receive and output the test signal to the control input terminal.

  • Patent number: 11728945
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform uplink reference signal bundling for access link communications and transmit sidelink communications using time or frequency division multiplexed resources. The UE may determine to drop or to transmit a sidelink communication based on a relationship with multiple instances of an uplink reference signal that are to maintain phase continuity. The UE may drop a sidelink communication when a time duration between two instances of the uplink reference signal is less than or equal to a time threshold value, and may transmit the sidelink communication when the time duration exceeds the time threshold value. In frequency division multiplexed cases, the UE may set a transmission power for each instance of the uplink reference signal, and the sidelink communication may use a remaining amount of power.
