VR5: Why I could not establish call use CWM500 use 2x2-Bi-FDD topology?

Answer
When use this topology with CMW500, due to the delay introduced by VR5 on uplink, set 5~10dB loss on uplink to make establish connection with basestation first
After UE and base station establish connection, adjust downlink and uplink path loss properly according to the test requirement
