Hi All,
If we increase cra port number from 4 to 2 for 4T4R will traffic increase?
My mcs is increased and cqi is degraded, so can I implement DL flexible bler feature and cqi adaptive?With less initial adjust meant to improve cqi?
Will it work?
Vendor is Huawei.
Better trial the feature in small clusters with different type of clutter, terrain, or demographic.
We’ll have better profiling over those clusters.
It worked quite well, since not all NE suitable for certain features.
Yes, you will get 3 dB gain in UE side but will loss MIMO gain.
It is good to use it in road and rural where you have coverage issue.
What kind of gain does it have? It’ll just give you a bit more power of the totally Rru power to use for the reference signal, and maybe just maybe it marginally improve the coverage, not noticeable anyway
a theoretical gain of 3 dB is possible in 4Rx compared to 2Rx which will enhance coverage at the cell edge due to the lowering of the usable SINR.
2Rx to 4Rx will enhance the UL channel quality (SINR,BLER )
Di you mean the ul sinr increase with 2tx to 4tx?
Yes ,UL PUSCH SINR
