Coded Caching with Joint Content Recommendation and User Grouping

Caching is a technique that can efficiently reduce the peak traffic by storing content files locally during off-peak times. Recommendation systems help enhance the cache hit ratio by recommending content files to users. In this paper, we propose a grouped recommendation-aided coded caching scheme, also referred to as GRACE, which achieves a good tradeoff between the peak rate and the average hit ratio. In GRACE, the base station (BS) recommends...
