“…For an SVC scenario, a scalable video stream consists of a base layer a 1 and (A − 1) enhancement layers, i.e., a 2 , a 3 , ..., a A . The operational mode Q b (b = a, .., A) is defined as the scenario when the first b layers are selected for transmission [25].…”

“…We hereby define the term "resolution" to indicate the level of temporal segmentation and the number of ELs [25]. To this regard, if BL is guaranteed to be delivered, while more ELs can be also obtained when the link can afford it, a better video quality can be expected.…”

“…Therefore, enhancing video transmission over LTE has become an important issue. There were several approaches to optimize video delivery efficiency over LTE [23]- [26]. Most consider resource allocation (or scheduling) for multiple video streams which share communication resources [23]- [25].…”

“…The optimization is performed with consideration of a delay constraint, average data rate and available data rate. Yang et al [26] proposed to adaptively change the video source bit rate according to the variation of the expected data rate. Note that this requires re-encoding Cross-layer optimization model between application layer and PHY/MAC layers for video QoE enhancement.…”

“…However, the insights provided can be used in future works to study the scenarios with limited buffer capacities, where the buffer overflow events can also affect the end-to-end packet delays due to the need for repeated transmissions. In such scenarios, for reducing buffer overflow incidents, a buffer-aware source rate control mechanism can be exploited to adjust the traffic load in the network [17]. Also, buffer-aware resource allocation methods similar to [18] can be employed to efficiently serve the system queues.…”
