gain&loss (decay, signal power, ...)
either a fixed gain in dB, a target power in dBm or ACG (automatic control gain) to a target average
=> don't redo the AGC, as it was used in UE case, that must have a AGC inside the UE
will be better to handle the "set_gain()" called by UE to apply it's gain (enable test of UE power loop)
lin_amp = pow(10.0,.05*txpwr_dBm)/sqrt(nb_tx_antennas);
a lot of operations in legacy, grouped in one simulation signal decay: txgain*decay*rxgain
multi_path (auto convolution, ISI, ...)
either we regenerate the channel (call again random_channel(desc,0)), or we keep it over subframes
legacy: we regenerate each sub frame in UL, and each frame only in DL
