Abstract (in Japanese) (See Japanese page) 
(in English) This paper focuses on coded caching when every user has a different memory size for caching and studies the design over multiple-input single-output (MISO) wireless channels. Specifically, we consider a network composed of a base station with multiple antennas and multiple users with a single antenna and design beamforming, applying the conventional coded caching to the network. We quantitatively show that the conventional coded caching is not optimal in terms of transmission rate when the spatial degree-of-freedom (DoF) is exploited and further propose a new optimization to design the caching phase. Numerical results confirm the improvement of our proposed caching.
