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