- Tutorial on "Emerging topics in small-cell networks: evolution towards 5G solutions", organized by Adrian Kliks (PUT, Poland) and Jordi Perez-Romero (UPC, Spain)

?   Part I

?   Part II

PART 1 – INTRODUCTION AND REVIEW (approx. duration 45 mins)

The goal of the first part is to remind, summarise and organise the fundamental issues related to the small cells; this will be done in the form interesting for the experts in the field (as a brief overview) and as introduction for those who starts they adventure in small-cell networks

 ?   Introduction  (approx. duration 15 mins)

?   Key concepts in the small-cell application

In this introductory part the fundamental aspects of the application of small-cells will be presented, such as the concept itself, typical problems such as interference and resource managements, security, privacy, deployment strategies etc.

?   Role of small cell networks in the 5G network

Small cell networks are envisaged by many researchers as one of the technical enablers that will allow the efficient management of the increased traffic in next-generation cellular networks; in this short part we will examine how the small cells could be applied for these purposes

?   Development of small-cell networks (approx. duration 30 mins)

?   Evolutionary roadmap in the framework of cellular networks

As a continuation of the introductory part, the roadmap of the small cells evolution in the recent cellular networks standards will be presented, showing the solutions available on the market for 3G and 4G networks; the architecture evolution will be briefly analyzed

?   Het-Nets in the context of WiFi Alliance

The term small cell contains also the WiFi Access Points, thus it is necessary to provide the listeners with the concise summary of the evolution of the standards from the 802.11 family, focusing on the connection between WiFi and cellular networks.

?   Key problems in HetNets deployment

As the summary of this part, the key problems in HetNets deployment will be briefly identified, including not only technological problems but also legal issues

 PART 2 – INTRODUCTION AND REVIEW (approx. duration 3h)

After presentation of the basics, the second and main part will be devoted for presentation of the three dedicated areas related to the small cell networks, i.e. backhauling, coexistence of various networks and context-aware networking. 

  • Backhauling design for the small cells (1 h 10 min)
  • Introduction to the backhauling

In order to discuss later the detail on the specific aspects of backhauling, some fundamental problems will be discussed here.

  • Key aspects of the backhaul design (delay, latency, coverage, throughput, synchronisation)

Following the generic introduction to that subject, now the key problems will be analyzed in details. In particular it is envisaged that the issues related to latency and delay of the backhaul will be discussed, followed by the coverage and capacity problem, finishing on synchronisation aspects and legal issues.

  • Existing technologies (e.g., microwave links, sub-6 GHz, TV White Spaces, fiber or coaxial networks, etc.)

The problem of backhaul connection between the small cell base station and the core network can be solved in various ways. In that part the pros and cons of the possible technological solutions will be presented.

  • Multiple technologies small-cells (1h 10 min)
  • Coexistence of 3GPP and non-3GPP networks

The concept of 3GPP and non-3GPP networks coexistence has been studied for many years. However, from the perspective of 5G networks it seems that very efficient solutions are at our fingertips. The key aspects related to this subject will be presented.

  • Existing solutions for cellular networks (e.g., Access Network Discovery and Selection Function, LIPA, SIPTO, IFOM, MAPCON, non-seamless Wi-Fi offloads etc.)

Generic discussion will be followed by the detailed description of the techniques already considered or foreseen to be applied in the future standards.

  • The concept of Hotspot2.0 (including  ANQP and other techniques)

The coexistence of various network types will be possible only if the appropriate solutions will be prepared in parallel for these networks. As previously the discussion concentrated on the cellular networks, now the main focus will be put on the WiFi network and the solutions proposed there.

  • Handover procedures

As an example of coexistence, the problem of vertical handover will be presented followed by the traffic offloading schemes.

  • Security aspects

As the summary of that part short discussion on the security aspects will be provided. 

  • Context aware networking  (40 min)
  • Application of REMs for Small Cells

As it will be highlighted in the previous part for multi technology small cells, the coexistence is possible if the context information can be easily accessed and exchanged. Thus in this part the visionary concept of the application of Radio Environment Maps for the better coexistence of various types of network will be presented.

  • Interference management and radio resource management

The concept of REMs application for Small Cells will be analysed in the context of interference and radio resource management
