  • Patent number: 12149389
    Abstract: Systems, devices, and methods for isolating digital signals are described. A carrier signal can be modulated using a first signal to generate a first modulated signal. The carrier signal and the first modulated signal can be transmitted through a forward path in an isolation barrier, where transmitting the carrier signal through the isolation barrier can transform the carrier signal into a delayed carrier signal. The first modulated signal can be demodulated to recover the first signal. The delayed carrier signal can be modulated using a second signal to generate a second modulated signal. The delayed carrier signal and the second modulated signal can be transmitted through a return path in the isolation barrier, where the return path and the forward path has opposite directions.

  • Patent number: 12136981
    Abstract: An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.
