TL;DR: The objective of this article is to present a new framework for MAC and RRM layers for supporting eDSA and requirements of the next-generation networks.

TL;DR: To allow the system to adapt to the anticipated heterogeneity, some properties need to be pursued, like simplicity, flexibility, scalability, versatility, efficiency and future proofness.

TL;DR: This paper presents the vision and some early results achieved by the EU-funded SPEED-5G project which is part of 5G PPP and proposes a novel 5G system architecture based on both the Network Slicing paradigm and a new Media Access Control layer that facilitates Multi-RAT access and allows prioritising and allocating traffic across heterogeneous access technologies.

TL;DR: A hierarchical radio resource management scheme using small and macrocells would allow cellular users to reuse and exploit potentially underutilized spectrum portions to overcome the issue of limited resources.

TL;DR: The paper elaborates on the technological and architectural innovations researched and developed by 5G-PPP Phase 1 projects and covering innovation areas such as 5G system design and evaluation, novel air interfaces, network management and security as well as virtualization and service deployment aspects.
