Abstract: 5G, a future descent cellular network is predictable to encourage the increasing demand for continuous rising mobile users and the egression of services like the internet of things. Enormous MIMO has been specified as a promising technology that presents important improvements in the efficiency of spectral over 4G technologies. Although, pilot contamination is the prime restricted factor while considering the TDD protocol. Several manners have been offered in literature to diminish the influence of pilot contamination in mobile systems. This paper provides an overview of the proposed a spatiotemporal approach which can mitigate the effect of pilot contamination by avoiding time-domain transmitting synchronous pilot and then a pilot allocation algorithm in the spatial domain. The proposed scenario provides a reduced level of intercell interference, which eventually gives it the ability to enhance the minimum and the mean achievable strength per terminal.
