# What is the SINR in V2X for different vehicles sharing the same sub-channel?

I read different papers in v2x such as A Two-Stage Resource Allocation for SCMA-Based C-V2X Networks and Deep Reinforcement Learning for Resource Allocation in V2V Communications but I'm really confused about how to calculate the interference if three vehicles are sharing the same subchannel. I have the same setting Deep Reinforcement Learning for Resource Allocation in V2V Communications but the difference that I have more than one RSU. For example, if I have 4 vehicles share the same subchannel where

vehicle1 sends data to vehicle2
vehicle 3 sends data to RSU1
vehicle 4 sends data to RSU2


Is the interference of V2I will be different than the interference in the mentioned papers or not?
