“…In practice, the resource allocation can be performed periodically every subframe. According to NR-MBMS, all subframes, i.e., 100% of the available radio resources, can be allocated for broadcasting services [4,5]. In broadcasting, the UE experiencing the worst CQI in the group (receiving the broadcast content in an MBSFN area) governs the radio resource allocation parameters.…”

The popularity of immersive multimedia content is prevalent and the consumption of 360 • videos is increasing rapidly in varied domains. The broadcast of such content in cellular networks will be challenging in terms of dynamic content adaptation and efficient resource allocation to serve heterogeneous consumers. In this work, we propose an intelligent immersive new radio multimedia broadcast multicast system (NR-MBMS), I2MB, for next-generation cellular networks. I2MB intelligently forecasts the users' viewing angle and the 360 • video tiles to be broadcast beforehand using long short-term memory network. We define broadcast areas by using modified K-means clustering. The complex multivariable optimization problem that integrates efficient adaptive 360-degree video encoding and tiled broadcast using optimized transmission parameters is defined as as a Markov Decision Process (MDP) . In a dense urban scenario with a large MBSFN synchronization area, the state and action space dimensionality is very high, in which the solution is obtained by using Deep Deterministic Policy Gradient (DDPG) algorithm. I2MB incorporates Deep Reinforcement Learning based radio resource allocation (modulation-coding scheme and frequencytime resource blocks) and tiled video encoding to maximize the viewport video quality experienced by the broadcast mobile users. I2MB provides improved immersive video broadcast streaming quality while serving a higher number of mobile users. Adaptive encoding of 360 • video tiles and radio resource allocation are performed based on users' forecasted viewing angle, spatial distribution, channel conditions, and service request. The performance evaluation of our proposed scheme, I2MB, shows considerable gains in viewport quality ( 46.83%) and number of users served ( 30.52%), over a recent state-of-the-art method VRCAST.INDEX TERMS Multimedia broadcast and multicast services (MBMS), New Radio MBMS (NR-MBMS), 360 • video, Viewing angle prediction, Immersive tiled video.

“…Moreover, several other features, such as IoT connections, ultralow latency, high data rate, energy efficiency, coverage, and capacity, should be addressed by SDAI. The spectrum accessibility is increased with the help of other fundamental techniques, such as low-density parity-check codes, turbo codes, MIMO, Orthogonal Frequency-Division Multiplexing (OFDM), and other rated techniques [180][181][182]. Moreover, recent advances in link-level technology in terms of antenna innovations, coupled with the evolving system-level network architecture, are all expected to boost spectrum utilization efficiency in future 6G networks; such advances include the emerging M-MIMO and distributed antenna systems.…”

Issues, Challenges, and Research Trends in Spectrum Management: A Comprehensive Overview and New Vision for Designing 6G Networks

With an extensive growth in user demand for high throughput, large capacity, and low latency, the ongoing deployment of Fifth-Generation (5G) systems is continuously exposing the inherent limitations of the system, as compared with its original premises. Such limitations are encouraging researchers worldwide to focus on next-generation 6G wireless systems, which are expected to address the constraints. To meet the above demands, future radio network architecture should be effectively designed to utilize its maximum radio spectrum capacity. It must simultaneously utilize various new techniques and technologies, such as Carrier Aggregation (CA), Cognitive Radio (CR), and small cell-based Heterogeneous Networks (HetNet), high-spectrum access (mmWave), and Massive Multiple-Input-Multiple-Output (M-MIMO), to achieve the desired results. However, the concurrent operations of these techniques in current 5G cellular networks create several spectrum management issues; thus, a comprehensive overview of these emerging technologies is presented in detail in this study. Then, the problems involved in the concurrent operations of various technologies for the spectrum management of the current 5G network are highlighted. The study aims to provide a detailed review of cooperative communication among all the techniques and potential problems associated with the spectrum management that has been addressed with the possible solutions proposed by the latest researches. Future research challenges are also discussed to highlight the necessary steps that can help achieve the desired objectives for designing 6G wireless networks.

The provision of terrestrial broadcast services using 3GPP technologies was enabled for the first time in LTE Advanced Pro Release (Rel‐) 14, in which the evolved Multimedia Broadcast Multicast Service (eMBMS) technology was enhanced to fulfill a wide set of requirements input by the broadcast industry. During the Enhancements for Television (EnTV) work item in Rel‐14, several modifications were realized affecting system architecture, core, and radio access, which include, an interface to grant control to broadcasters to establish audiovisual services, an application programming interface for developers to simplify access to eMBMS procedures, or a transparent delivery mode with native content formats, among others. At the radio layer, dedicated carriers with 100% broadcast content allocation, and also new OFDM numerologies to support larger intersite distances in Single Frequency Networks (SFNs), were enabled. The most significant change was the so‐called receive‐only mode which enables devices receiving broadcast content without the need for uplink capabilities, SIM cards, or network subscriptions, i.e. free‐to‐air reception.In Rel‐16, 3GPP carried out a study item to evaluate EnTV Rel‐14 against the terrestrial broadcast requirements for 5G defined in 3GPP TR 38.913. Two requirements were detected as not met: the ability to support SFNs with cell radii of up to 100 km and mobile reception with speeds up to 250 km h−1. A Rel‐16 work item standardized further improvements while taking into account practical considerations such as implementation complexity and performance. The improved system is known as LTE‐based 5G Terrestrial Broadcast, and also with the popular name 5G Broadcast.
