Summary The popularity of the electric vehicles has been growing due to the concern of increase in environmental pollution. In order to overcome the environmental issues, electric vehicles have been introduced all over the globe. As the use and number of electric vehicles is growing, there is a great demand to identify the sustainable solutions for intelligent charging station dedicated to electric vehicles. The objective of this paper is to explore the possibilities for intelligent charging station using 5G services. This paper is a state‐of‐the‐art concept to identify the current challenges and issues of intelligent charging station. It should be noted that in the future, the use of the smart charging station will dramatically improve the efficiency of current charging stations. It is identified based on several existing techniques that the biggest challenges are the connectivity between the vehicles and among different charging stations. This manuscript could be useful for researchers working on intelligent charging station worldwide and on their integration with the recent communication technologies like 5G. The features of intelligent charging stations combined with the fifth‐generation network represent a new path for humanity and introduce a safer and more advanced environment. From data privacy to human safety, the network provides enough resources to rise driving quality, time and fuel economy and human lives saving. The results of this research can be well applied in the industry or in the field of academic research.

“…It is well-known that mmWave channels exhibit a sparse multipath profile [53]. When we consider the effective channel including the directional receive antenna with fixed pointing direction (e.g., pointing along the driving direction of the vehicle), it has been shown in measurements that a restriction to N c = 2 is well justified for mmWave transmissions [24,25,47,51]. This is because the directional receive antenna acts as a spatial filter that effectively reduces the already sparse mmWave multipath propagation environment to one (typically, the line-of-sight) or two (an additional nonline-of-sight) dominant paths.…”

“…We next investigate the average number of required CBs for a maximal bound violation probability p max = 10 −5 , as a function of the number of transmit antennas N t ∈ [12,24] and N u = 6 simultaneously active links. Notice, this bound violation probability corresponds to a packet transmission success probability of 99.99999 %.…”

“…Under line of sight (LOS) conditions, for example, it is often sufficient to account for a single strong so-called specular component of the channel plus a Rayleigh fading component that accounts for diffuse background scattering. More accurate models take into account two strong specular components, in order to model multipath interference effects [24]. The applicability of such models for vehicular communications has been demonstrated experimentally by measurements and ray-tracing simulations of vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) scenarios [25,26].…”

In this paper, we consider wireless transmissions over directional multiple-input single-output (MISO) two wave with diffuse power (TWDP) fading channels, subject to interference over the same type of channel. TWDP fading is known to exhibit an outage behavior that can be even worse than Rayleigh fading and has experimentally been observed in a number of vehicular channel measurement campaigns. To enhance the reliability of multi-point transmissions over MISO TWDP fading channels, we propose a zero-forcing based coordinated beamforming scheme, for which we can analytically characterize and optimize the outage probability of the multi-point transmissions. Based on the developed outage expressions, we furthermore propose a greedy coordinated scheduling approach that attempts to maximize the achievable rate of the system. Finally, we propose a transmission rate adaptation scheme for fixed size packet transmissions, which supports reliable and at the same time resource efficient multi-point transmissions.

“…Although traditional automotive antennas, such as broadcast antennas and satellite navigation antennas, have been widely deployed in various automotive products, 5G millimeter wave communication system has put forward crucial requirements for the performance of vehicle antennas and vehicle RF front-end [2,3]. Limited by the overall vehicle design, the performance improvement and compactness design of vehicle antenna are currently important research issues for vehicular wireless communication [4][5][6].…”

This paper presents a high gain dielectric resonance antenna (DRA) array for vehicular wireless communication and 5G system in millimeter wave band, which takes the advantage of low side lobe level (SLL). The planar antenna array is composed of 8 × 8 rectangular DRA elements, whose operation mode is the fundamental mode TE 111 . The beamforming weights of the array are designed based on the principle of Dolph-Chebyshev distribution to suppress the antenna SLL. The planar array consists of 8 linear sub-arrays, which are fed with standing-wave series resonance method respectively. The excitations of sub-array elements are precisely adjusted based on the aperture coupling model. Furthermore, the series-parallel hybrid feed network and parallel-cascaded feed network are applied to unequally feed the sub-arrays in accordance with Chebyshev polynomials. The measurement results of prototype validate the design solution of antenna array. The impedance bandwidth is 570 for reflection coefficients less than −10 dB, and the antenna gain and SLL are 20.5 ± 1 dBi and 20 dB, respectively. Due to the advantages of miniaturization and narrow beam, the proposed DRA antenna array is adequate for vehicle communication equipment.
