Hello, I would like to ask how the interference in the lite SINR is calculated in the scenario of heterogeneous network, and whether the relationship between layers and interlayers is taken into account when calculating the interference.

Hello,

Please confer section 7.2 in the user manual for a more detailed outline of the lite SINR calculation. It should be emphasized, that due to undesired complexity, SISO transmissions are assumed for the desired as well as all interfering links for the lite SINR calculation. Hence, spatial (interlayer-) interference is ruled out by the SISO assumption and not taken into account.

hello! I am currently working on a 6G TN-NTN interference analysis project using the Vienna SLS simulator. I am looking for a Vienna SL programmer who can coordinate with me. You can approach me directly at this email [sarasualiheen@gmail.com](mailto:sarasualiheen@gmail.com). Thanks

dear sarasualiheen：  
Thank you for your invitation, but I don’t have extra time to help you finish the project in a short time. Besides, I’m not proficient in using the sls simulator in Vienna. If you have a project later, I have time, and I hope to have the opportunity to cooperate with you.  
best regards！
