  This paper considers the coexistence of two important communication
techniques, non-orthogonal multiple access (NOMA) and mobile edge computing
(MEC). Both NOMA uplink and downlink transmissions are applied to MEC, and
analytical results are developed to demonstrate that the use of NOMA can
efficiently reduce the latency and energy consumption of MEC offloading. In
addition, various asymptotic studies are carried out to reveal the impact of
the users' channel conditions and transmit powers on the application of NOMA to
MEC is quite different to those in conventional NOMA scenarios. Computer
simulation results are also provided to facilitate the performance evaluation
of NOMA-MEC and also verify the accuracy of the developed analytical results.
