The invention discloses a single-user large-scale antenna relay system power allocation method based on energy efficiency optimization. A communication system consists of a single antenna information source node, a single antenna information sink node, and a relay node transceiver configured with a large scale of antennas, and is shown in accompanying drawings in the summary. According to the method, a mathematical optimization model taking transmitting powers of the information source node and a relay node as design variables is built specific to a design objective of system energy efficiency maximization under a constraint condition of satisfying specified system quality of service (QoS). Since an accurate analytical expression is unavailable for an objective function in an optimization problem, an accurate approximate analytical expression of the objective function is obtained by means of a law of large numbers in a large-dimension random matrix theory. Then, a non-convex objective function is transformed into a convex function through interval approximation equivalence with a large signal-to-noise ratio. Through a Lagrange dual function convex optimization algorithm, a closed-form solution of a power allocation scheme is obtained finally by means of a Lambert W function, so that solving of the optimization problem with an alternate iteration method is avoided.
