Hi Experts, need practical experienced answer.
In LTE Mu-MIMO which transmission mode will give more benefit, TM4 or TM9?
Also, does TM9 will have some issues with Carrier Aggregation?
“It is recommended that the DrxSimulAckNackAndCqiSwitch be turned on in CA scenarios. If the CaCqiAndAckAbnCtrlSwitch cannot be turned off due to UE compatibility issues, it is recommended that downlink MU-MIMO in TM9 be disabled.”
Vendor is Huawei.
