Claim of US Patent No. 10,512,073

1. An apparatus of a user equipment (UE) for narrowband Internet-of-Things (NB-IoT) communication, the apparatus comprising:a memory; and
processing circuitry configured to:
monitor a set of narrow-band physical downlink control channel (NPDCCH) candidates;
each NPDCCH received on an aggregation of one or two consecutive narrowband control channel elements (NCCEs), each narrowband control channel element corresponding to six consecutive subcarriers in a subframe,
wherein a first NCCE occupies subcarriers zero through five in a subframe and a second NCCE occupies subcarriers six through eleven in a subframe,
wherein to monitor the set of NPDCCH candidates, the processing circuitry is to attempt to decode each NPDCCH candidate in the set,
wherein if downlink control information (DCI) is detected in a candidate NPDCCH and if the DCI schedules a narrow-band physical downlink shared channel (NPDSCH), the processing circuitry is configured to:
decode the NPDCCH using a narrowband reference signal (NRS),
wherein the NRS is received in NB IoT downlink (NB-IoT DL) subframes carrying the NPDSCH,
wherein the NRS is received in NB-IoT DL subframes before the scheduled NPDSCH, and
wherein the NRS is received in NB-IoT DL subframes after the scheduled NPDSCH.
