Patent ID: 11350449

Abstract:
Downlink transmissions can be generated to schedule one or more Internet of Things (IoT) devices for communication on unlicensed channels via frequency hopping operations/procedures. An evolved NodeB (eNB) or a next generation NodeB (gNB) can perform a listen before talk (LBT) on the unlicensed channels that are scheduled for transmission by at least one of: one or more IoT devices or one or more user equipments (UEs). A preamble or a common physical downlink control channel (CPDCCH) can be transmitted to reserve the unlicensed channels for the IoT devices/UEs. The preamble or the PDCCH can include a duration of the duration to provide notice to other eNBs/gNBs or trigger the IoT devices of a successful LBT corresponding to the unlicensed channels.
