Hi all,
Just wondering to know can anyone share how to calculate rank indicator 2 ratio in LTE Huawei?
As I know, rank indicator 2 means there is no interference/No correlation (Orthogonal) to each other of multiple antenna in MIMO system.
If rank indicator 1, it implies that the signal from the two Tx antenna is percieved by UE to be like single signal from single Antenna, which means the worst
performance.
For Example, in my network, we got a filter correction that if rank2 ratio is < 50%, this means the MIMO system expereince low rank indicator 2, but I don't
know which counter to calculate this ratio, I'm still new in LTE.
I'd be grateful if smb can answer my question :)
Thanks
