Hi,

I am running the launcher file of Cell association scenario, Can you please explain what figure 2 represents?

Hi Farhan,

The figure illustrates the user-BS assignment.  
The number specifies the BS to which the user at that position is assigned.

Thanks for answering,

As per scenario baseStations.nElements = 5;  
Whereas we have 15 in this figure? Can you please clarify.

Dear Farhan,

There are three sectors per BS.

Thanks, I do understand that this is a sample scenario, still does this scenario holds any research significance?

Can we fix the location of BS in this scenario? What changes would it require to the code?

Hi Farhan,

You can manually set the 2D position of the base station in the corresponding scenario file.

For example, you can find the following in +scenarios/example.m.  
predefinedBS = parameters.basestation.PredefinedPositions;  
predefinedBS.positions = [x; y];
