Movable-antenna trajectories are optimized to maximize the minimum user rate, yielding finite optimal deployment patterns with time allocations in the infinite-speed case and a heuristic for limited speed.
Movable antenna systems exhibit a fundamental tradeoff between movement duration for improved channels and transmission time, optimized via 1D search or a fitting method that yields a closed-form speed threshold below which stationary antennas are optimal.
