Background: The rapid evolution from 4G to 5G has transformed the telecommunications landscape, but as technological demands continue to grow, the shift toward 6G is gaining attention. 6G aims to address the limitations of 5G, such as latency and bandwidth constraints, while introducing new capabilities like terahertz communication and ubiquitous AI integration. Objective: This article explores the development roadmap of 6G, highlighting its applications across industries and addressing key challenges in its deployment. Methods: A comprehensive review of current literature on 5G advancements and emerging 6G technologies was conducted. Comparative analyses were performed on the theoretical frameworks of 6G’s core capabilities, including network architecture, spectrum management, and AI integration. Results: The study identified key applications for 6G, such as smart cities, autonomous transportation, healthcare, and industrial automation. It also highlighted the anticipated improvements in data transmission speed, reliability, and connectivity. Conclusion: 6G represents a pivotal evolution in telecommunications, offering transformation in numerous sectors. However, challenges such as infrastructure development, regulatory frameworks, and energy efficiency must be addressed.

Background: Network slicing has turned out to be one of the key enablers in the 5G networks due to the ability to support the diverse applications such as ultra reliable and low latency communications for the self-driving cars or IoT-like massive machine type communications. Prior expeditions lacked integrated tools for the dynamic assignment and allocation of resources and no possibility for maintaining constant QoS. Objective: In this article, the primary aim is to synthesis and test a reinforcement learning–driven slicing framework in order to orchestrate the resources of the three types of slices – URLLC, mMTC, and eMBB. This is to improve the performance of the sliced resource, ensure high availability, and minimize competition of the resources in multi-tenant scenarios in 5G networks. Methods: The proposed study design includes a focus on the key stakeholders and their needs for requirements gathering and an experimental field for actual implementation. Resource distribution is guided by the reinforcement learning algorithms by trying to minimize a cost function which incorporates the relation between the latency, isolation, throughput and energy expended. Using a number of runs, quality of performance is monitored to enable assessment of stability as well as response rates. Results: Experimental results show that the proposed framework achieves a lower level of latency violations and capacity oversubscription compared to heuristic methods. Furthermore, it consistently achieves nearly 2.5X better throughput for telemedicine slices and guarantees less than 5 ms latency for time-sensitive services during dynamic traffic conditions. Conclusion: The study shows how reinforcement learning can be effective and applied for end-to-end 5G network slicing. This sort of adaptive orchestration can increase service dependability while optimising overhead and herald instantly climbable multi-tenant networks compatible with various industries
