Of course, set the gNB machine IP address if the UE and the gNB are not on the same machine
In UE, you can add "-d" to get the softscope
### Channel simulation
The RF channel simulator is called.
In current version all channel paramters are hard coded in the call to:
new_channel_desc_scm(bridge->tx_num_channels,bridge->rx_num_channels,
AWGN,
bridge->sample_rate,
bridge->tx_bw,
0.0, // forgetting_factor
0, // maybe used for TA
0); // path_loss in dB
Only the input noise can be changed on command line with -s parameter.
With path loss = 0 set "-s 5" to see a little noise
#Caveacts
Still issues in power control: txgain, rxgain are not used
