- Abstract
- We consider a scenario of data transmission in the uplink channel in a 5G Vehicle-to-Everything (V2X) network with remote vehicle control. The key features of this type of traffic are the variable size of generated packets and strict restrictions on packet delivery time. To serve the traffic of different users, the base station uses a hybrid radio resource allocation scheme: each user is assigned both a dedicated subchannel and a shared subchannel, which is used when there are insufficient resources in the dedicated channel to transmit a packet. We construct an analytical model of data transmission in the uplink channel using this scheme, which allows us to estimate the probability of packet loss for each user at given scheme parameters. We show how to use the analytical model to select the optimal parameters of the hybrid scheme that maximize network capacity.
