Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.

Abstract (eng): Relaying is emerging as one of promising radio access network techniques for LTE-Advanced networks that provide coverage extension gain with improved quality of service.
It enables improved high data rate coverage for indoor environments or at the cell edge by deploying low power base station.

The need for high-quality on-the-spot emergency care necessitates access to reliable broadband connectivity for emergency telemedicine services used by paramedics in the field.
In a significant proportion of recorded cases, these medical emergencies would tend to occur in indoor locations.
However, broadband wireless connectivity may be of low quality due to poor indoor coverage of macro-cellular public mobile networks, or may be unreliable and/or inaccessible in the case of private Wi-Fi networks.

To that end, relaying is one of the optimal solution to provide required indoor coverage.
This paper analyzes the use of nomadic relays that could be temporarily deployed close to a building as part of the medical emergency response.
The objective is to provide improved indoor coverage for paramedics located within the building for enhanced downlink performance (throughput gain, lower outage probability).

For that scenario, we propose a resource sharing algorithm based on static relay link with exclusive assigned sub-frames at the macro base station (MBS) coupled with access link prioritization for paramedic's terminals to achieve max-min fairness.
Via a comprehensive system-level simulations, incorporating standard urban propagation models, the results indicate that paramedics are always able to obtain improved performance when connected via the relay enhanced cell (REC) networks rather than the MBS only.
