To calibrate the Tx and Rx gain parameter you need to follow this steps : To calibrate the Tx and Rx gain parameter you need to follow this steps :
* 1.You have to first set the attenuation between the eNB and the UE: * 1 You have to first set the attenuation between the eNB and the UE:
The RSRP of the signal received on UE side should be between -75 and -95 dBm, so you have to set the attenuation to be in this range. The RSRP of the signal received on UE side should be between -75 and -95 dBm, so you have to set the attenuation to be in this range.
(See the screen shot in the Stats windows : RSRP[0] -85.32 dBm) (See the screen shot in the Stats windows : RSRP[0] -85.32 dBm)
* 2. The received signal on UE side should not saturate for this you have to play with Rx-gain * 2 The received signal on UE side should not saturate for this you have to play with Rx-gain
(See the received signal in the LTE DL SCOPE UE of the scrren shot, also in the stats windows you can see that i am using Rx-gain 105 dB) (See the received signal in the LTE DL SCOPE UE of the scrren shot, also in the stats windows you can see that i am using Rx-gain 105 dB)
