“…The authors made use of unicast bearers for unpopular content and showed considerable bandwidth saving over traditional DTV in urban environments. Along a similar theme, more recent work by Lau et al in [5] further explores broadcast television over cellular networks, once again reinforcing the concepts linking popularity and overall spectral efficiency gains. Further more, the work used real world data and scenarios to develop an audience-driven TV scheduling framework, optimising the scheduling of broadcast resources.…”

“…For example, physical multicast channel (PMCH) is introduced to carry user plane eMBMS data to eMBMS users in the cell. Resource allocation, coding and modulation configuration at PMCH can be further optimized for efficient LTE video broadcasting [54][55][56], although these prospects are rarely applied at mobile operators. …”

An exponential increase in mobile video delivery will continue with the demand for higher resolution, multi-view and large-scale multicast video services. Novel fifth generation (5G) 3GPP New Radio (NR) standard will bring a number of new opportunities for optimizing video delivery across both 5G core and radio access networks. One of the promising approaches for video quality adaptation, throughput enhancement and erasure protection is the use of packet-level random linear network coding (RLNC). In this review paper, we discuss the integration of RLNC into the 5G NR standard, building upon the ideas and opportunities identified in 4G LTE. We explicitly identify and discuss in detail novel 5G NR features that provide support for RLNC-based video delivery in 5G, thus pointing out to the promising avenues for future research.

“…Actually, the dominating complexity of the AMSA algorithm is determined mainly by the iteration number of the inner loop, which is equal to M iterations. There is also another factor that is involved in the AMSA algorithm complexity, which is the sample window length L of the two prediction functions (8) and (9). Consequently, the maximum number of iterations of the AMSA algorithm is equal to (2L × M) iterations, where L is a lesser term compared to M and therefore can be ignored, to obtain finally a linear computation complexity of O(M).…”

Meeting the growing demand for multimedia services is still the main challenge for the current mobile network technologies. The 3rd Generation Partnership Project has proposed an emerging technology called multimedia broadcast/multicast service (MBMS). This service is gaining traction as a method of efficiently using the scarce wireless resources for multicasting the same content to a large number of users belonging to the same area. In the multicast broadcast single frequency network (MBSFN) context, the conventional approach specified by the 3rd Generation Partnership Project standard adopts a semistatic resource allocation mechanism for MBMS services according to their quality‐of‐service parameters. More precisely, the resources assigned to all MBMS service flows remain unchanged along the transmission period and reallocation may take place only when a new multicast session is admitted for transmission or a current session ends. This approach is inefficient and not suitable, especially for services with variable bit rate such as live video streaming. In this paper, we propose a proactive resource allocation algorithm that can dynamically adjust the subframe allocation within an MBSFN area in order to keep pace with the variable bit rate traffics' fluctuations. The basic idea of the proposed solution is to periodically reallocate the MBSFN subframes, in case of persistent over or under allocations, based on a linear prediction model of the resources actually consumed and the traffic behavior. The simulation results show that our proposed algorithm can reduce the waste of MBSFN resources, which could be used for other multicast or unicast transmissions, without violating the quality‐of‐service and fairness constraints.
