Resolving the Feedback Bottleneck of Multi-Antenna Coded Caching
IEEE Transactions on Information Theory(2022)
摘要
Multi-antenna cache-aided wireless networks were thought to suffer from a severe feedback bottleneck, since achieving the maximal Degrees-of-Freedom (DoF) performance required feedback from all served users for the known transmission schemes. These feedback costs match the caching gains and thus scale with the number of users. In the context of the $L$ <...
