In order to responding to the aforementioned demands, non-orthogonal
multiple access (NOMA) has attracted much attention due to its ability to deal with massive connectivity, high latency, low throughput, and low reliability .
However, the enhanced rates of the UL and DL throughputs of the proposed scheme was achieved at the expense of a more pilot sequence requirement for channel state information estimation as a tradeoff with resources for data transmission within the coherence interval in comparison to conventional methods and also the scheme is still based on full pilot sequence initialization and reuse of non-orthogonal
pilot sequence in different cells in a multi-cell scenario which is the major source of PC.

To cope with these demands, non-orthogonal
multiple access (NOMA) scheme is proposed as the 5G radio access technology for the wireless mobile networks to efficiently utilize the bandwidth, support numerous number of users or nodes, provide low-overhead transmission, better user-fairness, enhanced cell-edge throughput, freedom from request-grant scheduling for connection establishment, improved QoS, and enable low-latency communication .
The chipset combines DOCOMO's non-orthogonal
multiple access (NOMA) radio access technology and MediaTek's multi-user interference cancellation (MUIC) technology, which is required to achieve NOMA.
The main goal of this paper is to show that one can construct a non-orthogonal
basis of the Krylov subspace such that the corresponding Q-OR method yields the same residual norms as GMRES when they are started from the same initial vector (except in case of GMRES stagnation); that is, one can construct what can be considered an optimal Q-OR method.
In 2017, ZTE initiated and played a leading role in the non-orthogonal
multiple access (NOMA) project, a core 5G NR project.
Currently there are a lot of researchers exploring how we can design non-orthogonal
multiple access by assigning a lot of IoT users/ devices with different quality of service requirements into the same time slot or frequency channels.
