  • METHOD AND APPARATUS FOR TRANSMITTING LTE WAVEFORMS IN SHARED SPECTRUM BY CARRIER SENSING
    Publication number: 20240236694
    Abstract: A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.
    Type: Application
