Abstract

Devices, methods, and non-transitory computer readable media perform steps for securing communications in a Multi-User (MU), Massive, Multiple Input Multiple Output (MIMO) network. The base station estimates an initial precoding matrix based on a first estimated value of a signal to interference plus noise ratio (SINR) and determines a kuser device outage probability value and an eavesdropper device outage probability value associated with the eavesdropper device. An optimized beamformer weight matrix is determined based on the user device outage probability value and the eavesdropper device outage probability value. The base station determines whether the optimized beamformer weight matrix satisfies at least one outage condition. When the outage condition is satisfied, the base station transmits the optimized beamformer weight matrix to each remote radio head, which transmits downlink signals using a kbeamformer vector of the optimized beamformer weight matrix.
