A low computational-cost subgrouping multicast scheme for emerging 5G-satellite networks

Performance of Resource Management Techniques for Weather-Impacted Satellite Networks

“…While some proposals are aimed at ensuring that accepted users are served with seamless and reliable connectivity, others focus on guaranteeing the satisfaction of users' individual quality of service (QoS) requirements throughout the period of their connection. For instance, the authors in [18,19] address the issue of resource allocation for multicast multimedia content delivery to large number of users in an integrated satelliteterrestrial network by developing a resource allocation strategy that considers the time-varying condition of the satellite channel in the allocation of network resources. While aiming to guarantee users' QoS requirements and maximize resource utilization, users are organized into subgroups based on their current channel conditions; resources are then allocated to users in each subgroup depending on the modulation and coding scheme (MCS) that is appropriate and selected for transmission in their current channel states.…”

Subgrouping‐based multicast transmission over high‐throughput satellite systems with beam cooperation

“…Moreover, the ever-increasing traffic demands of multicast services, such as online games, video meetings, and especially bandwidth-hungry video content delivery, further burden the system. 6,7 Hence, multimedia broadcast/multicast service (MBMS) and its evolved version (eMBMS for LTE) have been introduced by 3GPP to improve the transmission efficiency of multicast services in wireless networks. 8 The multicast/broadcast nature of satellite channels is a convenience for supporting multicast services.…”

“…Multicast services raise serious challenges to communication systems in terms of occupying numerous resources in serving separate users distributed in broad areas. Moreover, the ever‐increasing traffic demands of multicast services, such as online games, video meetings, and especially bandwidth‐hungry video content delivery, further burden the system 6,7 . Hence, multimedia broadcast/multicast service (MBMS) and its evolved version (eMBMS for LTE) have been introduced by 3GPP to improve the transmission efficiency of multicast services in wireless networks 8 …”
