Edge-caching is a promising technique to improve the network performance in terms of delivery latency and network congestion during peak-traffic times. Between the two fundamental methods, coded caching has received much attention due to its significant gain over the uncoded counterpart. In this paper, we propose an energy-efficient beamforming design for coded caching delivery phase in wireless networks context. In particular, by exploiting the broadcasting capability of the wireless channels and taking into the cache size, a multi-group multicast based transmission scheme is employed to deliver multiple coded messages to different subgroups of users simultaneously. Numerical results show a significant energy consumption reduction of the proposed design compared to the conventional scheme in the small and medium cache size regime.
