Interference-aware simultaneous transmission

Develop an interference-aware extension of the BeamCKMDiff communication and handover framework that supports simultaneous multi-base-station transmission.

Background

The system model assumes that base stations operate on orthogonal time-frequency resources, so inter-cell interference is absent. Multi-base-station interaction is restricted to handover decisions and predictive beam preparation rather than simultaneous transmission. The paper explicitly leaves interference-aware simultaneous transmission unresolved, indicating a need to reformulate the rate model and joint beamforming optimization to account for inter-cell interference.

References

The BSs operate on orthogonal time-frequency resources and therefore cause no inter-cell interference. The UAV is associated with one serving BS in each time slot; multi-BS interaction is limited to handover decisions and predictive beam preparation. Interference-aware simultaneous transmission is left for future work.
