    Question Re: Good RSRP, CINR but bad RSRQ ?

    Hi,

    RSRQ depends on on load in serving cell. In your case the testplan (i.e. downloading) is pushing RSRQ downwards. Do the same DT with low DL load, e.g. small ping packets

    Re: LTE PSS AND SSS

    Hi

    this little of guessing from my side, but:
    - if you are sending 2 PSS, detection of a cell is 2 times quicker - very important for incoming inter-freq & inter-rat mobility (like HO)
    - if...

    Re: LTE PSS AND SSS

    Hi,

    PSS allows quick correlation because there are only 3 sequences for PSS. Because of that, it just gives timing(or synch) for slot. Hence it is not possible to figure out where frame starts....

    Re: Huawei RB calculation vs NSN
