Fundamental Limits of Cloud and Cache-Aided Interference Management with Multi-Antenna Base Stations
In fog-aided cellular systems, content delivery latency can be minimized by jointly optimizing edge caching and transmission strategies. In order to account for the cache capacity limitations at the Edge Nodes (ENs), transmission generally involves both fronthaul transfer from a cloud processor with access to the content library to the ENs, as well as wireless delivery from the ENs to the users...
متن کاملFundamental Limits on Delivery Time in Cloud- and Cache-Aided Heterogeneous Networks
A Fog radio access network (F-RAN) is considered as a network architecture candidate to meet the soaring demand in terms of reliability, spectral efficiency, and latency in next generation wireless networks. This architecture combines the benefits associated with centralized cloud processing and wireless edge caching enabling primarily low-latency transmission under moderate fronthaul capacity ...
متن کاملCloud and Cache-Aided Wireless Networks: Fundamental Latency Trade-Offs
A cloud and cache-aided wireless network architecture is studied in which edge-nodes (ENs), such as base stations, are connected to a cloud processor via dedicated fronthaul links, while also being endowed with caches. Cloud processing enables the centralized implementation of cooperative transmission strategies at the ENs, albeit at the cost of an increased latency due to fronthaul transfer. I...
متن کاملFundamental Limits of Cache-Aided Private Information Retrieval with Unknown and Uncoded Prefetching
We consider the problem of private information retrieval (PIR) fromN non-colluding and replicated databases when the user is equipped with a cache that holds an uncoded fraction r from each of the K stored messages in the databases. We assume that the databases are unaware of the cache content. We investigate D∗(r) the optimal download cost normalized with the message size as a function of K, N...
متن کاملFundamental Limits of Heterogenous Cache
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 performance of the cache. In this work, for ...
