  This letter investigates a short-packet downlink transmission system using
non-orthogonal multiple access (NOMA) enhanced via movable antenna (MA). We
focuses on maximizing the effective throughput for a core user while ensuring
reliable communication for an edge user by optimizing the MAs' coordinates and
the power and rate allocations from the access point (AP). The optimization
challenge is approached by decomposing it into two subproblems, utilizing
successive convex approximation (SCA) to handle the highly non-concave nature
of channel gains. Numerical results confirm that the proposed solution offers
substantial improvements in effective throughput compared to NOMA short-packet
communication with fixed position antennas (FPAs).
