Claim of US Patent No. 10,973,014

9. An apparatus to be implemented in a MulteFire (MF) Narrowband (NB)-Internet of Things (IoT) user equipment (UE), the apparatus comprising:interface circuitry; and
baseband circuitry coupled with the interface circuitry, the baseband circuitry to:
detect a Narrowband Physical Downlink Shared Channel (NPDSCH) transmission ending in an NB-IoT downlink (DL) subframe n for which acknowledgement or negative acknowledgement (ACK/NACK) data is to be provided, wherein n is a number,
generate a Narrowband Physical Uplink Shared Channel (NPUSCH) format 2 message to include ACK/NACK data based on receipt of the NPDSCH transmission, and
control transmission of the NPUSCH format 2 message over an NPUSCH at an end of k?0?1 uplink (UL) subframes following an end of n+12 MF NB-IoT subframes in N consecutive NB-IoT UL slots, wherein N is a number, and k?0, is a number, and wherein the ACK data indicates a successful decoding of the NPDSCH transmission and the NACK data indicates an unsuccessful decoding of the NPDSCH transmission.
