Does anybody working on Huawei experienced issues related to coverage reduction.
I am getting issues from customer mentioning that he had previously good coverage but now it have reduced.No changes done in the site.
Yes, from qos indicators, you should be able to check the timing advance of the users. Also you can check the path balance of each TRX, as the problem might be related to only one TRX in the cell. (it can also be caused by a faulty cable or a faulty combiner, which would affect the coverage of all the TRXs)
