“…As shown in Figure 1, users who are located near the eNodeB receive the transmitted data at high bit rate using 64QAM, while cell edge users receive the transmitted data at low bit. This is in order to maintain the connection quality and link stability without the need to increase the transmission power (Fantacci et al, 2009;Cohen et al, 2010).…”

LTE broadcast or evolved multimedia broadcast multicast service (eMBMS) enables operators to efficiently launch media services over LTE to meet mobile users' demand on multimedia services. This paper introduces two mechanisms that use the standard deviation (StD) of eMBMS user's modulation and coding scheme (MCS) level group operated on single cell mode to select its optimal MCS level efficiently. Typically, MCS level is selected on the basis of users' worst channel condition, which results in wasting network resources. Since the eMBMS performance directly depends on the selected MCS level, an efficient adaptive modulation and coding (AMC) scheme is essentially needed. The proposed mechanisms are simulated using LTE simulator, and the results show that the proposed mechanisms increase the eMBMS performance in terms of throughput, delay and packet loss ratio, compared to the worst channel gain and averaging mechanisms.Keywords: enterprise networks; LTE; evolved Multimedia Broadcast Multicast Service; eMBMS; modulation and coding scheme; MCS; spectrum efficiency; adaptive modulation and coding; AMC.

“…In [18]- [20], how to choose the right modulation and coding schemes to ensure efficient and reliable multicast was studied. How to optimize power allocation for SPC was proposed in [21]; however, the optimal configuration of s-mod cannot be obtained using the power allocation scheme for SPC; therefore, the solution in [21] is not applicable here.…”

Abstract-In conventional wireless systems with layered architectures, the physical (PHY) layer equally treats all data streams from the upper layers and applies the same modulation and coding schemes to them. Newer systems such as Digital Video Broadcast start to introduce hierarchical modulation schemes with SuperPosition Coding (SPC) and support data streams of different priorities. However, SPC requires specialized hardware and has high complexity, which is not desirable for handheld devices. In this paper, we propose scalable modulation (s-mod) by reusing the current mainstream modulation schemes with software-based bit remapping. The performance evaluation has shown that s-mod can achieve the same and, in some cases, even better performance than SPC with much lower complexity. We further propose how to optimize the configuration of the PHY-layer s-mod and coding schemes to maximize the utility of video streaming with scalable video coding (SVC). Simulation results demonstrate substantial performance gains using s-mod and cross-layer optimization, indicating that s-mod and SVC are a good combination for video transmission in wireless networks.

Abstract-In conventional wireless systems with layered architectures, the physical layer treats all data streams from upper layers equally and apply the same modulation and coding schemes. Newer systems such as Digital Video Broadcast start to introduce hierarchical modulation schemes with SuperPosition Coding (SPC) and support data streams of different priorities. However, SPC requires specialized hardware and has high complexity beyond most existing handheld devices. We thus propose scalable modulation (s-mod) by reusing the current mainstream modulation schemes with software-based bit-remapping. In this paper, we study how to optimize the configuration of the physical layer s-mod and coding schemes to maximize the utility of videocast with Scalable Video Coding (SVC). Simulation results demonstrate significant performance gains using s-mod and the cross-layer optimization, indicating s-mod and SVC is a good combination for wireless video multicast and unicast.
