dc.description.abstractMeeting the requirements of the Low-Power Wide Area Network (LPWAN), Narrowband Internet of Things (NB-IoT) is the most promising technology being come across to date. Currently, the NB-IoT framework is operating on 180 kHz bandwidth with 15 kHz subcarrier spacing using OFDM for Downlink and 3.75 kHz and 15 kHz subcarrier spacing using SC-FDMA for Uplink respectively for single-tone and multi-tone transmission. Several research activities have already pointed to several lacking of the current NB-IoT framework. In this manuscript, firstly, the design of the current framework of NB-IoT is discussed. Secondly, to ensure an increment in the number of connected UEs, we proposed a modified resource grid over the current scheme using the 1.875 kHz subcarrier spacing for the singletone uplink data transmission and investigated its performance under different scenarios using Vienna 5G Link Level Simulator
