In this paper, we first consider the random caching and carefully analyze the signal-to-interference-plus-noise ratio from the perspective of a typical user, deriving the expression of successful transmission probability. Then, our objective is to maximize the successful transmission probability by optimizing the caching distribution in high SNR using proposed subgradient descent method. Finally, simulations illustrate that the caching distribution optimized by our proposed algorithm achieves a gain in successful transmission probability over existing caching distributions.
