The development of Internet of Things (IoT) raises new problems, namely the limitations of the spectrum used. The 5 Generation network is considered a communication network that can provide high capacity and high-speed data transmission. It is possible to combine 5G and IoT because 5G network has flexibility to support variaton of devices and services. non-orthogonal multiple access (NOMA) is considered as promised technology on 5G to support the needs of higher transmission rate because NOMA can transmit more user at the same frequency or time. Allocation of different user signal power to the same sub-channel even in the same sub-channel according to the related algorithm on the NOMA transmitter with superposition code. The popular combination on researches recently are NOMA, cooperative and simultaneous wireless transmission (SWIPT). These technologies are currently being research with other methods to improve the data rate with the flexible combination. In this paper, we compare technologies that combine with NOMA to improve the data rate.
