Achievable rate regions for cooperative relay broadcast channels with rate-limited feedback

Achievable rate regions for cooperative relay broadcast channels with rate-limited feedback are proposed. Specifically, we consider two-receiver memoryless broadcast channels where each receiver sends feedback signals to the transmitter through a noiseless and rate-limited feedback link, meanwhile, acts as a relay to transmit cooperative information to the other receiver. The proposed rate regions improve on the known regions that consider either relaying cooperation or feedback communication, but not both.
