Does this Configuration correspond to Tx or Rx Antenna gain? And is it UL or DL?

// 1x1 is fine if you just want a fixed element gain; increase rows/cols for array gain. // --- NTN gNB(s) --- nrHelper->SetGnbAntennaAttribute("NumRows", UintegerValue(64)); nrHelper->SetGnbAntennaAttribute("NumColumns", UintegerValue(64)); Ptr<IsotropicAntennaModel> ntnElem = CreateObject<IsotropicAntennaModel>(); ntnElem->SetAttribute("Gain", DoubleValue(30.0));

Thank you in advance

This gain is the antenna element gain (single tile of the antenna panel). The full antenna gain is computed based on a bunch of things.
