    Default Question about Interference - Using MOD3

    Team,


    I've checked the previous posts about the rules and consecuences when we use MOD3 and MOD30

    I'd like to know the interference impact in a practical scenary where 4 cells have the same PSS , for example :

    PCIs : 76 / 388 / 394 / 94 all PCI MOD3 = 1 (PSS) My question is: This scenary gets low SINR and so low THP? Have you faced with this and please, what is the recommendation?

    BR





    Thank you for your support!

    It's right. It's low SINR, RSRQ and low throughput. Need to change or plan again this areas.

    if you have MOD3 in this case the SINR will be effected and also the throughput so is better to avoid MOD 3 by changing the PCI ,thx

    Thank you @mounir34 and @hieuphong

    Is there another thing to do instead of change PCI planning? In this case, coverage was adjusted!
