The invention discloses a method for optimizing the throughput of a multiuser multi-antenna digital-energy integrated communication network. The method is composed of base station downlink beam design, multiuser receiver energy probability computation, power allocation and time slot allocation. According to the method disclosed by the invention, a multi user RFDC circuit threshold, limited user battery capacity and dynamic allocation are considered to better approach to actual constraint, the energy receiving fairness of users with different distances in the multiuser multi-antenna digital-energy integrated communication network is improved, and the minimum throughput of the uplink data transmission between the users is increased.
