“…To overcome this limitation, the opportunistic approach [16] endeavors to serve, in any given time slot, only a portion of multicast users in order to maximize a given objective function, such as system throughput. The goal of this approach, named Multicast Link Adaptation (MLA) [12], is to exploit the multi-user diversity in the resource allocation process, although it may limit the multicast gain, i.e., the number of users successfully served in each time slot. As a consequence, additional data coding (e.g., rateless codes) is required for ensuring the users keep the transmitter informed of which portion of file is received.…”

“…The idea proposed for the OSS approach, is to include in the space definition process all the candidate configurations that satisfy the conditions (13) and (4a). In this way, all the configurations that are not admissible for the solution of the problems (7), (8) and (12) are not evaluated in the space definition process. Due to this fact, the number of configurations generated by the OSS is significantly reduced with respect to the ESS scheme.…”

Multimedia content delivery over satellite systems is considered as a promising service in emerging 5G networks. The aim of this paper is to design a novel radio resource management algorithm for efficiently managing multicast multimedia content transmission over satellite network. The proposed approach performs the spectrum management on a per-group basis, by splitting multicast terminals into different subgroups according to the experienced channel qualities. We demonstrate that subgrouping policy defined by the authors as multicast subgrouping-maximum satisfaction index (MS-MSI), based on a new metric (i.e., MSI), overcomes the weakness of the previous techniques proposed in the literature and provides the best tradeoff between user throughput and fairness. As a further result, we demonstrate that MS-MSI is robust to the long propagation delay of satellite links. An extensive simulation campaign has been conducted by considering several satellite environments

This paper investigates the multicast transmission for multicast services in high-throughput satellite (HTS) systems. Considering the multibeam multicast feature of HTSs, cooperative transmission among beams is involved in to improve the efficiency of the multicast transmission. Since the multicast transmission rate depends on the worst user channel state, all the users experience an unreasonably low rate. In this situation, subgrouping techniques are employed to increase transmission rates of users. A subgrouping-based multicast transmission problem aiming at maximizing the lowest transmission rate of the users is studied to guarantee fairness among users. We formulate the problem as a max-min optimization problem and propose two low-complex subgrouping algorithms for this problem. Additionally, we also consider multicasting in a single beam and devise a two-layer transmission scheme for it. In the performance evaluation part, besides the impact of parameters on subgrouping performance, we analyze the performance and the computational complexity of the proposed algorithms. The results indicate that the two subgrouping algorithms can achieve favorable performance with low complexity.

The next generation of mobile radio communication systems-so-called 5G-will provide some major changes to those generations to date. The ability to cope with huge increases in data traffic at reduced latencies and improved quality of user experience together with a major reduction in energy usage are big challenges. In addition, future systems will need to embody connections to billions of objects-the so-called Internet of Things (IoT) which raise new challenges. Visions of 5G are now available from regions across the world and research is ongoing towards new standards. The consensus is a flatter architecture that adds a dense network of small cells operating in the millimetre wave bands and which are adaptable and software controlled. But what is the place for satellites in such a vision? The chapter examines several potential roles for satellites in 5G including coverage extension, IoT, providing resilience, content caching and multicast, and the integrated architecture. Furthermore, the recent advances in satellite communications together with the challenges associated with the use of satellite in the integrated satellite-terrestrial architecture are also discussed.
