Hello Experts.
Does anyone know where I can find the “RankIndicator” parameter, and does it relate to MIMO?
Maybe you are talking about the parameter MAXMIMORANKPARA in MO CELLDLSCHALGO. (For Huawei)
Usually we are using Rank = 2 in 4*4 MIMO, in ZTE network.
RI is number of uncorrelated signal paths with sufficiently high SNR. On those BTS/Scheduler can map data (layers). It’s one of the CSI parameters UE reports back. It is closely related to MIMO, where RI can never be higher than your MIMO order (physically impossible), it can only be equal or lower.
All vendors have related parameters on Cell level but also you can see counters from UE reporting, for example Ericsson has pmRadioUeRepRankDistr.
