MIMO 2x2 - ADAPTIVE Parameter


#1

Hello,

What is the disadvantage of changing MIMO 2x2 from NO_ADAPTIVE to CL_ADAPTIVE with Initial ADAPTIVE?

Hello Cesar,

From OL to CL, there is a trade-off. OL gets better throughput in fast moving environment and CL gets better throughput in stable radio conditions.

For NO_ADAPTIVE, i did not see any comparison in Huawei docs. but i would guess since there is not TM change, it is not recommended. i.e. wasting resources when radio conditions are not appropriate.

In our network, we use CL for LTE-TDD and OL for LTE-FDD.
