Congratulations to Daria Ostrikova on the scholarship of the President of the Russian Federation!

“When I received the scholarship, first I was proud of the Department of Applied Probability and Informatics, and of our entire scientific team. After all, undoubtedly, this is our common victory!

“I plan to continue to actively participate in scientific activities and in a couple of years to enter the defense of my doctoral thesis. The topic of energy efficiency I expect to develop models of user service with a given quality of service and energy efficiency in heterogeneous 6G communication networks with several simultaneously active interfaces (LTE/NR/THz), inter- and intra-multi-connectivity. I also plan to develop recommendations for network operators and manufacturers of network and subscriber equipment for different types and stages of 6G communication network deployment,” — said Daria Ostrikova.

Why is this research important and promising?

Problem

New communication network augmented service and virtual reality, telepresence, 8/16K video and various scenarios of their use require higher speeds in the wireless access area. The most promising communication system for this is 6G. It will use the highest frequencies of the millimeter and terahertz bands, their bandwidth is an order of magnitude higher. However, there are some limitations in the use of these frequency bands.

Task

To improve the energy efficiency of user device service in 6G networks and maintain a given quality of service, it is necessary to develop:

• mathematical models to account for device service interruptions in the terahertz band;
• system-level analysis and design methods in terahertz networks that take into account the mobility, macro and micro mobility of user devices.

Solution

The RUDN scientist's project is aimed at finding methods and developing mathematical models that will eliminate the effects of negative effects when using high frequencies of the millimeter and terahertz ranges.

Prospective result

Recommendations on user session service management in 6G access networks will be developed, important data for current research will be obtained, and the results will be used for 6G network design.
