Coded caching can be applied in wireless multi-antenna communications bymulticast beamforming coded data chunks to carefully selected user groups andusing the existing file fragments in user caches to decode the desired files ateach user. However, the number of packets a file should be split into, known assubpacketization, grows exponentially with the network size. We provide a newscheme, which enables the level of subpacketization to be selected freely amonga set of predefined values depending on basic network parameters such asantenna and user count. A simple efficiency index is also proposed as aperformance indicator at various subpacketization levels. The numericalexamples demonstrate that larger subpacketization generally results in betterefficiency index and higher symmetric rate, while smaller subpacketizationincurs significant loss in the achievable rate. This enables more efficientcaching schemes, tailored to the available computational and power resources.
