N2 - In this paper, we investigate the beamforming and power control issue in cellular-connected unmanned aerial vehicle (UAV) communications under full-duplex (FD). To mitigate the self-interference (SI), we adopt a decoupled uplink (UL)-downlink (DL) association for UAVs to spatially separate the transmit and receive beams. Then, we formulate a joint beamforming and power control problem to maximize the system's spectral efficiency (SE) while ensuring each UAV meets its UL transmission rate and DL latency requirements. To solve this problem, we design a novel distributed heterogeneous graph neural network (HGNN) architecture for beamforming and power control with a low signaling overhead. Simulation results demonstrate that our proposed scheme outperforms the existing schemes in terms of the total SE, UL transmission rate and DL latency.
