“…However, in order to minimize the difficulties with mobility management and signalling in ultradense networks, one could split them [32]. In other words, the exchange of control information can be made with a given BS, whereas the user data exchange can be made with another one.…”

Abstract-Existing cellular technologies are rapidly coming to their performance limits. This is due not only to the growth in data traffic and in the number of connected terminals, but also because we are on the verge of new era, where everyone and everything will be connected, with more demanding and varied requirements that cannot be satisfied by current networks. On account of this, efforts are being made all over the world to design new wireless technologies that will support the expected demands for the next decade. These technologies, embraced under the commercial name of 5 th generation, are currently being studied, and in this tutorial paper we will give an overview of the main trends that are likely to make their way in the next-generation standards.

“…By doing this, even if the connection to the small cell is lost or the beam interrupted, the UE would still be connected to its management entity, and connection would not be lost. The smaller cells, which do not contain management and signalling mechanisms, are also known as phantom cells [32].…”

“…The motivations and the major benefits of the Phantom cell architecture are similar to those of advanced C-RAN architecture for LTE-Advanced, which include enhanced capacity by small cells, easy deployment of higher frequency bands, and small cell deployment without impact on mobility management. However, the concept of Phantom cell architecture includes a wider range of advanced functionalities, such as inter-node aggregation, relaxed backhauling and signaling requirements, and enhanced small cell discovery [7], [8]. Our 5G concept uses the Phantom cell architecture as the baseline, upon which to integrate future multi-layer networks using lower and higher frequency bands.…”

SUMMARY Currently, many operators worldwide are deploying Long Term Evolution (LTE) to provide much faster access with lower latency and higher efficiency than its predecessors 3G and 3.5G. Meanwhile, the service rollout of LTE-Advanced, which is an evolution of LTE and a "true 4G" mobile broadband, is being underway to further enhance LTE performance. However, the anticipated challenges of the next decade (2020s) are so tremendous and diverse that there is a vastly increased need for a new generation mobile communications system with even further enhanced capabilities and new functionalities, namely a fifth generation (5G) system. Envisioning the development of a 5G system by 2020, at DOCOMO we started studies on future radio access as early as 2010, just after the launch of LTE service. The aim at that time was to anticipate the future user needs and the requirements of 10 years later (2020s) in order to identify the right concept and radio access technologies for the next generation system. The identified 5G concept consists of an efficient integration of existing spectrum bands for current cellular mobile and future new spectrum bands including higher frequency bands, e.g., millimeter wave, with a set of spectrum specific and spectrum agnostic technologies. Since a few years ago, we have been conducting several proof-of-concept activities and investigations on our 5G concept and its key technologies, including the development of a 5G real-time simulator, experimental trials of a wide range of frequency bands and technologies and channel measurements for higher frequency bands. In this paper, we introduce an overview of our views on the requirements, concept and promising technologies for 5G radio access, in addition to our ongoing activities for paving the way toward the realization of 5G by 2020.

“…In addition to the above, the proposed scheme could be considered as a natural fit to the emerging split-architectures for 5G wireless networks [57], [58], [59]. In split architectures signaling nodes are responsible for the coverage and are usually assumed to deliver low rate services, over long ranges; whereas pico-cells data nodes can be activated and deactivated depending on the traffic demand and it is designed for high rate and small ranges.…”

Abstract-Undeniably the support of data services over the wireless Internet is becoming increasingly challenging with the plethora of different characteristic requirements of each service type. Evidently, about half of the data traffic shifted across the Internet to date consists of multimedia content such as video clips or music files that necessitate stringent real-time constraints in playback and for which increasing volumes of data should be shifted with the introduction of higher quality content.This work recasts the problem of multimedia content delivery in the mobile Internet. We propose an optimization framework with the major tenet being that real-time playback constraints can be satisfied while at the same time enabling controlled delay tolerance in packet transmission by capitalizing on prefetching and data buffering. More specifically two strategies are proposed amenable for real time implementation that utilize the inherent delay tolerance of popular applications based on different flavours of HTTP streaming. The proposed mechanisms have the potential of achieving many-fold energy efficiency gains at no cost on the perceived user experience.
