5G communication system is rapidly taking shape and for many organizations, including administrations, it is important to be aware of developments in this regard. At this stage, it is essential to know about 5G use cases and possible key technologies. This paper describes several anticipated 5G use cases across a handful of different sectors. It is important to remember that these comprise only a subset of possible use cases and these are all still new. As-yet more new use cases are expected to emerge and the need to prepare their adaption in 5G and beyond. From wireless transmission, wireless access and network perspectives, the possible key technologies of 5G, including Massive Multiple Input Multiple Output (MIMO), Beam-forming, Device-to-Device communication system (D2D), non-orthogonal multiple access (NOMA), Full duplex, Small cells, cognitive radio(CR), etc. and their latest progress are presented comprehensively and thoroughly. Each has enormous advantages but also limitations. The Full duplex which will help to double the capacity of the channel compared to the Half-duplex technology of 4G and Small cells combined with millimeter waves to have a wide bandwidth. These Small-Cells are essential for energy reduction and also for improving latency. But these Small-Cells require the use of intelligent antennas, that is to say, the diagrams of which are directive and reconfigurable at the request of the user Future research challenges regarding 5G and beyond wireless communication are also discussed.

High throughput capability of the terahertz band (0.3-10 THz) wireless communications is expected to be utilized by the fifth generation of mobile telecommunication systems and enable a plethora of new applications. Supporting devices will transfer large amounts of data in both directions, causing high energy consumption by the electronic circuitries of the equipment in use. Therefore, physical layer for these systems must be designed carefully in order to reduce energy consumption per bit. In this paper, the best performing modulation scheme and hardware parameters that minimize the energy consumption without affecting the system throughput are determined. THz band device technologies are outlined and a complete survey of the state-of-the-art low-THz band circuit blocks which are suitable for mass market production is given. It is shown that for short-range communications, M-ary quadrature amplitude modulation is the most energy-efficient technique that can lead up to 90% reduction in consumed energy. Moreover, optimal transceiver parameters which can be used to further minimize the energy consumption of the THz band system are examined.

In cellular networks, the performance of the adaptive beamforming algorithms is severely degraded by the presence of the interfering signals. In this paper, we introduce a beamforming based algorithm for 5G applications named Direction Finding for Beamforming and Synthesizing (DFBS). This algorithm combines the Direction of Arrival (DOA), adaptive beamforming, and the radiation pattern synthesizing. The proposed algorithm uses the DOA technique to feed the adaptive beamforming algorithms with estimations of the desired user direction, desired user signal, and the interfering signals with their directions as initial values. In addition, we use the adaptive beamforming process to supply the radiation pattern synthesizing algorithms with an initial radiation pattern, and the required positions of nulls. At the beamformer output, we evaluate our proposed mechanism in terms of the error convergence, tracking capabilities, and the obtained radiation pattern characteristics. At the synthesizer output, we carry out analysis in terms of the convergence speed and the resultant radiation pattern attributes to investigate the efficiency of the proposed algorithm. The simulation results show that, our proposed algorithm has significantly fast convergence, reliable tracking capabilities, and radiation patterns with very low Side Lobe Levels (SLL).2010 MSC: 00-01, 99-00
