—Recently, a novel technique called coded cache have been proposed to facilitate the wireless content distribution. Assuming the users have the identical cache size, prior works have described the fundamental performance limits of such scheme. However, when heterogenous user cache sizes is taken into account, there remains open questions regarding the(More)
—The rapid growth of data volume and the accompanying congestion problems over the wireless networks have been critical issues to content providers. A novel technique, termed as coded cache, is proposed to relieve the burden. Through creating coded-multicasting opportunities, the coded-cache scheme can provide extra performance gain over the conventional(More)
Recent studies show that the coded caching technique can facilitate the wireless content distribution by mitigating the wireless traffic rate during the peak-traffic time, where the contents are partially prefetched to the local cache of mobile devices during the off-peak time. The remaining contents are then jointly coded and delivered in multicast, when(More)
