  Multi-antenna coded caching (CC) techniques are considered viable options for
achieving higher data rates in future networks, especially for the prominent
use case of multimedia-driven applications. However, despite their
information-theoretic analyses, which are thoroughly studied in the literature,
the research on the finite-SNR performance of multi-antenna CC techniques is
not yet mature. In this paper, we try bridging this gap by breaking down,
categorizing, and studying the effect of six crucial parameters affecting the
finite-SNR performance of multi-antenna CC schemes. We also investigate the
interaction of different parameters and clarify how they could affect the
implementation complexity in terms of the necessary computation and
subpacketization. Theoretical discussions are followed and verified by
numerical analysis.
