Abstract

Communication propagation between a drone and a HetNet (Heterogeneous Network) gNB (generalized Node B) in uplink conditions. The drone moves on a straight path between built-up environments. The communication frequency of 10 GHz can affect oksigen and water vapor at that frequency. Propagation of communication systems in a building environment can cause diffraction. The diffraction mechanism was modeled with Single Knife Edge (SKE) method. AMC (Adaptive Modulation and Coding) dynamically modifies the coding rate and modulation scheme according to signal quality. MCS (Modulation and Coding Scheme) consisting of QPSK, 16QAM, and 64QAM was used in AMC. Research analysis includes SNR values ​​on the drone path, coverage percentage, and MCS percentage. As a result of research for MCS 64QAM coderate 4/5 with Selection Combining (SC) between HetNet gNB macrocell and gNB femtocell, 64 nodes or 95.52% were obtained. The communication coverage was obtained using MCS for drone communication on this route.
