Abstract:This paper presents a joint optimization of caching and multicast beamforming for a content-centric transmission in a fog radio access network (F-RAN). Users requesting the same file are grouped together and served using multicast transmission. Each edge node (EN) has a local cache and can pre-store contents via partition-based caching. To improve cache performance and reduce fronthaul cost, the maximum distance separable (MDS) code is applied to the file coding. We consider the mixed timescale joint optimizat… Show more
