The JLEC 2019 paper
H. Joudeh, E. Lampiris, P. Elia, G. Caire, 'Fundamental Limits of Wireless Caching under Uneven-Capacity Channels,' ISIT 2019 + TIT 2020
Definitive treatment of the separation theorem. Theorem 1 achievability and Theorem 2 converse are the analytical core.
Broadcast channel capacity
A. El Gamal and Y.-H. Kim, Network Information Theory, Chapter 5
The classical theory of degraded BC capacity and superposition coding. Pre-requisite for this chapter.
Heterogeneous caches and fairness
K. Wan and G. Caire, 'Coded Caching with Heterogeneous Cache Sizes,' IEEE Trans. IT 2020
Extends JLEC to non-uniform cache sizes. Relevant for deployments where different user tiers get different cache budgets.
Rate-splitting multiple access (RSMA)
B. Clerckx et al., 'A Primer on Rate-Splitting Multiple Access,' IEEE WCL
A practical scheme closely related to JLEC's superposition mechanism. Useful for understanding deployable variants.
