In my previous message, when I said “BCC”, I actually meant “TSC”. Replace all instances of BCC by TSC… it is the couple (freq, TSC) that shall not be repeated among cells nearby each others.
Anyway, the main questions still remains :
– why is there a relationship between BCC and TSC ?
– why only on TS0 ? since cells are not sync, the TS5 of a cell might very well fall inside the TS0 of another cell.
