Beamforming codebook optimization in a wireless communication system (WCS) is provided. In a WCS, a wireless node (e.g., base station) simultaneously emits multiple reference beams in a coverage area based on a set of codewords that is optimized for a specific number (a full or a partial set) of antenna elements in an antenna array. The wireless node is configured to determine a different set(s) of codewords that are fine-tuned for forming the reference beams from a different number of the antenna elements in the antenna array and steer the reference beams toward identical directions. During deployment of the wireless node, there may be dead zones or low coverage zones. Aspects of the present disclosure facilitate the discovery of these low-coverage zones using feedback from multiple deployed Internet of Things (IoT) devices. Based on the feedback, the codebook of codewords may be optimized to reduce or eliminate such low coverage zones. Such an approach reduces reliance on manual walk-throughs and complicated iterative processes currently in use.
