Abstract
Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for periodic transmission on a set frequency of an anchor channel for U-IoT in an adaptive frequency hopping system. The anchor channel can include a clear channel assessment (CCA) period, an extended CCA (eCCA) period when a failure occurs during the CCA period, a tuning period for radio frequency (RF) retuning with frequency hopping, and a control information communication period for communication of the control information.

1-23. (canceled)
An apparatus of an evolved Node B (eNB) operable to communicate over an anchor channel in a MulteFire (MF) bandwidth reduced low complexity and coverage enhancement (BL/CE) cell, the apparatus comprising:
- one or more processors configured to:
- encode, at the eNB, a discovery reference signal (DRS) for transmission on the anchor channel in the MF BL/CE cell, wherein the anchor channel comprises:
- a clear channel assessment (CCA) period;
- an extended CCA (eCCA) period when a sensed channel during the CCA period is busy;
- and
- a period for communication of the DRS on a subframe;
- and
- a memory interface configured to retrieve from a memory the DRS.
An apparatus of a user equipment (UE) operable to decode information received over an anchor channel for Unlicensed Internet of Things (U-IoT), the apparatus comprising:
- one or more processors configured to:
- decode, at the UE, control information that is periodically received from a Next Generation NodeB (gNB) on a set frequency of an anchor channel for U-IoT in an adaptive frequency hopping system, wherein the anchor channel comprises:
- a clear channel assessment (CCA) period;
- an extended CCA (eCCA) period when a failure occurs during the CCA period;
- a tuning period for radio frequency (RF) retuning with frequency hopping;
- and
- a control information communication period for communication of the control information;
- and
- a memory interface configured to send to a memory the control information.
At least one machine readable storage medium having instructions embodied thereon for communicating over an anchor channel for Unlicensed Internet of Things (U-IoT), the instructions when executed by one or more processors at a Next Generation NodeB (gNB) perform the following:
- encoding, at the gNB, control information for periodic transmission on a set frequency of an anchor channel for U-IoT in an adaptive frequency hopping system, wherein the anchor channel comprises:
- a clear channel assessment (CCA) period;
- an extended CCA (eCCA) period when a failure occurs during the CCA period;
- a tuning period for radio frequency (RF) retuning with frequency hopping;
- and
- a control information communication period for communication of the control information;
- and
- a memory interface configured to retrieve from a memory the control information.
