In this paper a J shaped planar inverted F antenna (PIFA) is proposed which covers 4G LTE (Long Term Evolution) and 5G NR (New Radio) band of 3.5 GHz. The substrate material used is FR4 of thickness 1mm and overall dimensions as 100 mm x 50 mm conformal to mobile devices. The proposed PIFA exhibits wide bandwidth coverage of 450 MHz (3.25 GHz to 3.70 GHz). The structure is low profile with height of J shaped element above ground plane of 4mm. The J shape helped in achieving wider bandwidth and compact radiating element size compared to a conventional PIFA structure. The resonant frequency is 3.48 GHz and the peak gain is 3.74 dB. The proposed antenna covers n77 and n78 bands of 5G NR specifications as per International
Telecommunication Union (ITU) release document 16.

The next generation for mobile communication is new radio (NR) that supporting air interface which referred to the fifth generation or 5G. Long term evolution (LTE), universal mobile telecommunications system (UMTS), and global system for mobile communication (GSM) are 5G NR predecessors, also referred to as fourth generation (4G), third generation (3G) and second generation (2G) technologies. Pseudo-noise (PN) code length and modulation technique used in the 5G technology affect the output spectrum and the payload of DL-FRC specification, in this paper quadrature phase shift keying (QPSK), 16 QAM modulation approaches tested under additive white Gaussian noise (AWGN) in term of bit error rate (BER) which used with 5G technology system implemented with MATLAB-Simulink and programing and, resulting of 1672, 12296 bit/slot payload at frequency range FR1 from 450 MHz-6 GHz and 4424, 20496 bit/slot payload at frequency range FR2 from 24.25 GHz-52.6 GHz, also determining subcarrier spacing, allocated source block, duplex mode, payload bit/slot, RBW (KHz), sampling rate (MHz), the gain and the bandwidth of main, side loop where illustrated.

The Third Generation Partnership Project (3GPP) has recently published its Release 16 that includes the first Vehicle-to-Everything (V2X) standard based on the 5G New Radio (NR) air interface. 5G NR V2X introduces advanced functionalities on top of the 5G NR air interface to support connected and automated driving use cases with stringent requirements. This article presents an in-depth tutorial of the 3GPP Release 16 5G NR V2X standard for V2X communications, with a particular focus on the sidelink, since it is the most significant part of 5G NR V2X. The main part of the paper is an in-depth treatment of the key aspects of 5G NR V2X: the physical layer, the resource allocation, the quality of service management, the enhancements introduced to the Uu interface and the mobility management for V2N (Vehicle to Network) communications, as well as the coexistence mechanisms between 5G NR V2X and LTE V2X. We also review the use cases, the system architecture, and describe the evaluation methodology and simulation assumptions for 5G NR V2X. Finally, we provide an outlook on possible 5G NR V2X enhancements, including those identified within Release 17.

The millimeter wave (mmWave) communication is now considered as a predominant technology for fifth generation (5G) systems to meet the surging needs of traffic by ensuring massive bandwidth with high dimensional antennas. However, transmission control protocol (TCP) analysis due to mobility is still complex in nature. In addition, packet trip length, i.e., round trip time (RTT) and length of congestion window (CWND) need to be more investigated. In this paper, the executed framework of mmWave channel modeling has been inspected with ns-3 simulator. In this research, we consider several mobility models (e.g., constant mobility, Gaussian Markov, and random direction 2D) for a UE who is using mmWave link to communicate with eNB to transfer its traffic. These TCP analysis may be utilized to exhibit the potential of 28 GHz mmWave band and its worthy for the design of future 5G networks.
