Wake up signal for machine type communication and narrowband-internet-of-things devices

An apparatus of evolved NodeB (eNB), the apparatus comprising:

• processing circuitry arranged to:
• determine that a user equipment (UE) supports use of a wake-up signal (WUS) when in one of an idle mode or connected mode Discontinuous Reception (cDRX) state;
• determine that data is to be transmitted to the UE when the UE is in the idle mode or cDRX state;
• in response to a determination that the data is to be transmitted to the UE when the UE is in the idle mode or cDRX state, encode the WUS for transmission to the UE, the WUS comprising a sequence that is less complicated than a physical downlink control channel (PDCCH);
• and
• encode, for transmission to the UE after transmission of the WUS, one of:
• paging information during a paging occasion (PO) when the UE is in the idle mode, the paging information encoded for the UE, or
• a physical downlink shared channel (PDSCH) when the UE is in the cDRX state, the PDSCH encoded for the UE;
• and
• a memory configured to store the WUS.

A computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the one or more processors to configure the UE to, when the instructions are executed:

• receive a wake-up signal (WUS) configuration from an evolved NodeB (eNB) that indicates that a WUS is supported by the eNB, the WUS being less complicated than a physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH);
• enter one of an idle mode or connected mode Discontinuous Reception (cDRX) state;
• and
• dependent on a coverage level of the UE, wake up from the one of the idle mode or cDRX state at a resource indicated by the WUS configuration and determine whether the WUS has been received;
• and
• in response to a determination that the WUS has been received, wake up for reception of a PDCCH for the UE in a paging occasion (PO) when the UE is in the idle mode or a physical downlink shared channel (PDSCH) for the UE when the UE is in the cDRX state.
