摘要In this paper, we examine the content delivery design for a cache-aided cloud radio access network (CA-CRAN), where users are served by multiple base stations (BSs) that are connected to cloud processor via fronthaul link. We propose a unified framework for cooperative delivery, which aims to minimize the total latency in the network. With fairness among users and physical-layer transmission, beamformers and content assignment are jointly optimized to fully exploit the benefits of caching. To address the resulting mixed binary nonconvex problem, a successive convex approximation (SCA)-based algorithm is derived with low complexity. Through simulations, the proposed design reduces latency significantly compared with existing work.
