I have a specific problem that never seen before, need your help on that issue.
I have a cell which have 6 TRx. And my main problem is that average dl signal strength is too low(-107db) on BCCH Trx.
* When I swap signalling channels on other TRx and this time that new BCCH TRx degrades.
* When I lock BCCH Trx, new BCCH assigned TRx degrades.
When i check signal stregth of per TRx, always only BCCH TRx has low DL signal strenth, other hopping TRx’s are working normal. When i swap BCCH on that normal working hopping TRx, that time i have same problem on that new BCCH TRx and old BCCH TRx improves.
Hope i explained my problem well.
Thanks in advance.
