Abstract: In embodiments, a base station may be able to identify whether a user equipment (UE) is to operate within the cellular network in accordance with a wideband (WB) protocol or a narrowband (NB) protocol. Based on this identification, the base station may further be able to identify a number of resource blocks (RBs) that include subcarriers occupied by enhanced narrowband control channel elements (eNCCEs). Finally, the base station may be able to transmit the eNCCEs on the subcarriers. Other embodiments may be described and/or claimed.

Abstract: Technology for a user equipment (UE) operable for MulteFire (MF) narrowband (NB) internet of things (IoT) is disclosed. The apparatus can comprise one or more processors configured to: decode a special subframe from a data segment carried on an nframe that is transmitted in a data channel; identify a downlink pilot time slot (DwPTS) and a guard period (GP) from the special subframe; and switch from receiving in the data channel to transmitting in the data channel during a duration of the special subframe.

Abstract: Systems and methods of using a frame structure by a NB-IoT UE are described, The UE receives an anchor segment on an anchor channel and a data segment on a data channel both in an unlicensed spectrum. If a 3N1 frame structure is used: a NPSS, NSSS and NPBCH are in a highest index anchor carrier of contiguous anchor carriers and SIB in a lowest index anchor carrier, and if a 3N2 frame structure is used a single narrowband carrier comprising the NPSS, NSSS, NPBCH and SIB. The data channel is a FHSS single carrier other than the anchor carriers if the 3N1 frame structure is used and the single narrowband carrier if the 3N2 frame structure is used. A NPDCCH or NPDSCH is received on a middle index anchor carrier or in the data segment. The NPSS overrides a TDD configuration indicated by the eNB.

Abstract: Embodiments of the present disclosure provide for narrowband reference signals transmission. A base station is configured to: generate downlink transmissions for unlicensed Internet of things (U-IoT) communication, the downlink transmissions to include an anchor segment on a first plurality of subframes and a data segment on a second plurality of subframes, wherein the anchor segment includes a narrowband reference signal (NRS) configured to be transmitted at a first transmit power by the base station, to facilitate time or frequency tracking and cause transmission of the downlink frame for the U-IoT communication. And a user equipment is configured to receive the NRSs transmitted by the base station and process transmissions based on reception of the NRSs.

Abstract: An apparatus and method for frequency hopping in the unlicensed band are described. A NB-IoT UE receives a MIB from a RAN. The MIB includes a DL/UL configuration for communication with the RAN. Frequency hopping information is preconfigured in the UE. The MIB is received in an anchor segment of a fixed NB anchor channel in the unlicensed band. The frequency hopping sequence is determined based on timing information carried in a PBCH on the anchor channel. Data is communicated between the NB-IoT UE and the RAN in data segments on the data channels in accordance with the frequency hopping sequence.
