A mathematician from the People’s Friendship University of Russia (RUDN) proposed a model for calculating the best parameters of a 5G network for VR applications. The result was published in the “Future Internet” magazine.

5G technology is designed to support applications that have high requirements for network speed. To achieve quality effects, broadcast technologies including multicast are used. This is a routing solution. Send data to all users (broadcast), but send data to a group of dedicated users. However, the use of multicast can have a negative impact on network performance because the data transmission rate in a group of users is limited by the speed of the user equipment with the weakest signal. A mathematician at RUDN University took VR applications as an example and proposed an algorithm model that combines multicast and unicast transmission. Based on this model, people will be able to estimate how many base stations are needed in the current network environment.

“To date, most of the research conducted on multi-layer multicast/unicast services has focused on optimizing the configured deployment for a given traffic condition. However, for network operators, it is estimated that a given random traffic in a given area The base station density required for the load is also important.” said Dr. Daria Ostrikova, deputy director of the Institute of Applied Mathematics and Communication Technology, RUDN University.

RUDN mathematicians proposed a model with multiple base stations. Each base station has three antennas covering 120°. VR device users will move randomly within the service station according to the Poisson point process model. It runs on three levels, uses multicast at the basic level, and improves communication quality based on unicast delivery. For this reason, a mathematician calculated the network parameters of the system and proposed an algorithm and requirements for multicasting by user groups. The calculation method of base station density.

Dr. Daria Ostrikova said: “Our numerical results show that the proposed grouping scheme can clearly calculate the number and configuration of groups and evaluate the performance of the millimeter wave communication system. Our work provides a simple and efficient algorithm to It is used to estimate the base station density required to support a given VR device density and specific quality of service parameters.”
