abstract = {The introduction of Narrowband Internet of
Things (NB-IoT) as a cellular IoT technology aims to support
massive Machine-Type Communications applications. These
applications are characterized by massive connections from a
large number of low-complexity and low-power devices. One of
the goals of NB-IoT is to improve coverage extension beyond
existing cellular technologies. In order to do that, NB-IoT
introduces transmission repetitions and different bandwidth
allocation configurations in uplink. These new transmission
approaches yield many transmission options in uplink. In this
paper, we propose analytical expressions that describe the influence of these new approaches in the transmission. Our analysis
is based on the Shannon theorem. The transmission is studied
in terms of the required Signal to Noise Ratio, bandwidth
utilization, and energy per transmitted bit. Additionally, we
propose an uplink link adaptation algorithm that contemplates
these new transmission approaches. The conducted evaluation
summarizes the influence of these approaches. Furthermore, we
present the resulting uplink link adaptation from our proposed
algorithm sweeping the device’s coverage.},
