A two-user coded caching problem is studied in a joint source-channel coding framework. A source generates symbols at a certain rate for each file in the database, and a fixed fraction of the symbols are cached at each user. The delivery phase of coded caching takes place over a time-varying erasure broadcast channel, where the channel state information is only available at the receivers. The maximum source rate to keep up with the ergodic rate of both users is characterized.
