Design of early termination signal and harq-ack feedback for pusch

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

• processing circuitry arranged to:
• decode, from a user equipment (UE), capability information that indicates that the UE supports use of an early termination signal (ETS) from the eNB, the ETS configured to indicate successful reception by the eNB of data transmitted by the UE on a physical uplink shared channel (PUSCH);
• encode, for transmission to the UE on a machine type communication (MTC) Physical Downlink Control Channel (MPDCCH), a schedule for transmissions of the data and ETS monitoring instances for the ETS from the eNB, the schedule based on a coverage level of the UE;
• determine whether the data transmitted by the UE has been successfully decoded;
• in response to a determination that the data has been successfully decoded, transmit the ETS during one of the monitoring instances closest in time after the determination, the ETS configured to indicate early termination of one of repeated instances of the data prior to an end of a scheduled transmission period or early termination of MPDCCH monitoring;
• and
• a memory configured to store the schedule.

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:

• transmit, to an evolved NodeB (eNB), capability information that indicates that the UE supports use of an early termination signal (ETS) from the eNB on a machine type communication (MTC) Physical Downlink Control Channel (MPDCCH), the ETS configured to indicate successful reception by the eNB of data transmitted by the UE on a physical uplink shared channel (PUSCH),
• receive, from the eNB, a schedule for repeated transmissions of data on the PUSCH, the schedule based on a coverage level of the UE;
• encode, for transmission to the eNB, repetitions of the data on the PUSCH;
• after transmission of the data for a predetermined number of the repetitions of the data or during the transmission of the data, monitor the MPDCCH for the ETS;
• and
• in response to reception of the ETS signal, terminate transmission of remaining repetitions of the data when there are remaining repetitions, and enter a sleep mode when the ETS is for early termination of MPDCCH monitoring.
