| Abstract(in English) | Space-air-ground integrated networks (SAGINs) are going to be a key technology of 6G for achieving the goal of global and ubiquitous coverage. SAGIN is a multi-layered integrated network of satellites and aerial objects such as high-altitude platform stations (HAPS) and ground terminals (GTs). HAPs act as a relay between satellites and GTs to improve the quality of communication. The existing works on full-duplex relay transmission in SAGINs considered fixed uplink and downlink transmission power by flying objects. The fixed uplink and downlink transmission power for all satellites and GTs at HAPs can lead to a higher number of unsatisfied GTs due to loss in transmission at satellites and GTs owing to mobility and different locations. Therefore, in this paper, we propose a mathematical model that enables integrated control to distribute the transmission power of HAPS at both links according to the diverse communication requirements from each GT at different locations. The performance of the proposed approach is evaluated using numerical analysis and shows that our proposed model can improve the efficiency of two-way relay transmission in SAGINs. |
