Abstract
We consider the problem of communicating over the general discrete
memoryless broadcast channel (BC) with partially cooperating receivers.
In our setup, receivers are able to exchange messages over noiseless
conference links of finite capacities, prior to decoding the messages
sent from the transmitter. In this paper we formulate the general
problem of broadcast with cooperation. We first find the capacity
region for the case where the BC is physically degraded. Then, we
give achievability results for the general broadcast channel, for
both the two independent messages case and the single common message
case.
