Low-density parity check (LDPC) is a channel coding technique widely utilized in the 5G New Radio standard, it is of utmost importance in facilitating proficient and secure communication in noisy environments by effectively minimizing errors during data transmission. It is primarily used in the 5G New Radio (NR) standard for encoding user information on the physical downlink shared channel (PDSCH). The necessity to satisfy the increasing expectations for throughput, latency, and dependability led to the decision to deploy LDPC codes for user data, especially in the enhanced mobile broadband (eMBB) and ultra-reliable and low-latency communications (URLLC) scenarios of 5G networks. The present system proposes the use of NR-LDPC codes to transmit data across a lognormal multipath fading channel model in the presence of AWGN. Wireless communication channels often use a lognormal multipath fading channel model, where the received signal experiences both multipath fading and lognormal shadowing. The research investigates the effectiveness of NR-LDPC coding in improving QAM-OFDM system performance by analyzing two rate-compatible base graphs and comparing their effectiveness with an uncoded system. This analysis is crucial for optimizing communication network design, especially in scenarios where the integrity of data is of utmost importance. We introduce a new method to improve the 5G NR LDPC code capability under lognormal fading conditions. This approach develops a layered min-sum (LMS) algorithm to provide enhanced error-correcting capabilities. The developed and implemented decoding algorithm represents a significant advancement over traditional detection methods. The outcomes of the simulation provide evidence of the effectiveness of the proposed NR-LDPC coding techniques in terms of their error correction and identification capabilities. In addition, the developed LMS decoding algorithm was shown to significantly decrease the BER of the system.

We examine the changes in the commercial model adopted by the mobile ICT industry, due to the advent of 5G technology. This includes consideration of the challenges involved in rolling out a new infrastructure, which new markets this is likely to open up and how this affects partnering decisions. We show that as technology horizons expand, their degree of overlap increases and previously complimentary technologies may compete with each other, impacting the size of the addressable market. It is expected that 5G, whilst supporting its existing markets, will offer additional machine to machine, low latency and highly reliable services. We consider the synergies and the drivers for adoption for the wider 5G propositions and consider the impetus for more bandwidth and services and how the new technology impacts selling approaches. We identify the risks and uncertainties for the network providers and the likely requirements for a sustainable 5G business model and will describe our view of the steps necessary for a 5G successful outcome.

Nowadays, the requirements for data transmission and efficiency of IoT networks are increasing. Network efficiency at all levels can be increased by using 5G networks. In this paper, we simulate and analyse the LTE, enhanced Mobile BroadBand, and enhanced Mobile BroadBand with Millimeter-wave services in scenarios with different numbers of IoT nodes and analyze the energy consumption and energy efficiency achieved results. Simulated scenarios and results were obtained using NS-3. Energy and mmWave frameworks were analyzed in this work because they were the main part of the research.

Packet scheduling in 5G networks is extremely important because it is responsible for resource allocation and allows for increasing the efficiency of these networks. However, thanks to the scheduling algorithms used, data traffics are obtained with the required priorities and meeting the time limits. The paper presents an algorithm for download traffic scheduling in 5G networks, which takes priorities and deadlines into account. Simulation results show that the proposed scheduler provides robust latency performance with satisfied customer satisfaction.

W artykule zaprezentowano korzyści gospodarcze płynące z wdrożenia nowej generacji sieci mobilnych, tzw. sieci 5G, oraz omówiono wynikające z nich efekty społeczne, w tym spodziewany wpływ na rozwój społeczeństwa informacyjnego. Następnie przedstawiono wyzwania związane z wdrażaniem 5G w Polsce. W głównej mierze wynikają one z obecności barier o charakterze technicznym, ekonomicznym i prawnym, które mogą spowolnić proces wdrażania 5G w Polsce. W artykule przedstawiono również inicjatywy mające na celu identyfikację barier wdrażania sieci 5G oraz potencjalne sposoby ich likwidacji. W tym kontekście przedstawiono działania Instytutu Łączności na rzecz wdrażania 5G w Polsce, w tym poprzez organizację prac w kierowanym przez Ministra Cyfryzacji Porozumieniu na rzecz Strategii „5G dla Polski” oraz uczestnictwo w projekcie 5G@PL realizowanym w ramach strategicznego programu badań naukowych i prac rozwojowych „Społeczny i gospodarczy rozwój Polski w warunkach globalizujących się rynków – Gospostrateg”.

This paper discusses the economic benefits experienced by implementation of new, the 5th generation of mobile network (5G), and associated social effects, including the expected impact of the 5G on the information society. In the light of the expected development of 5G system, the authors present challenges related to implementation of 5G in Poland. The challenges mainly derive from social, economic and legal barriers that have a negative impact on effective implementation of 5G in Poland. The article presents also initiatives for identifying and removing these barriers. In this context, the paper presents activities of the National Institute of Telecommunications (NIT) for the implementation of 5G in Poland, including the Agreement on the „5G for Poland” Strategy that is led by the Ministry of Digital Affairs and the work performed within the agreement is directed by NIT. Moreover, NIT participates in 5G@PL project under the strategic program of scientific research and development „Social and economic development of Poland in the context of globalization – Gospostrateg”.
