标题： Rate Regions for Relay Broadcast Channels

摘要： 一个部分协作中继广播信道（RBC）是一个包含一个源节点和两个目的节点（目的节点1和目的节点2）的三节点网络，其中目的节点1可以作为中继来协助目的节点2。 获得了离散无记忆部分协作RBC的容量区域的内部和外部边界。 当中继功能被禁用时，内部和外部边界会减少到广播信道容量区域的新边界。 详细研究了四类RBC。 对于具有退化消息集的部分协作RBC，获得了内部和外部边界。 对于半确定性部分协作RBC和正交部分协作RBC，确定了容量区域。 对于具有不匹配退化子信道的并行部分协作RBC，确定了退化消息集情况下的容量区域。 当源节点只为目的节点2提供私有消息时，即信道简化为具有不匹配退化子信道的并行中继信道时，也确定了容量。 显示英文摘要

摘要： A partially cooperative relay broadcast channel (RBC) is a three-node network with one source node and two destination nodes (destinations 1 and 2) where destination 1 can act as a relay to assist destination 2. Inner and outer bounds on the capacity region of the discrete memoryless partially cooperative RBC are obtained. When the relay function is disabled, the inner and outer bounds reduce to new bounds on the capacity region of broadcast channels. Four classes of RBCs are studied in detail. For the partially cooperative RBC with degraded message sets, inner and outer bounds are obtained. For the semideterministic partially cooperative RBC and the orthogonal partially cooperative RBC, the capacity regions are established. For the parallel partially cooperative RBC with unmatched degraded subchannels, the capacity region is established for the case of degraded message sets. The capacity is also established when the source node has only a private message for destination 2, i.e., the channel reduces to a parallel relay channel with unmatched degraded subchannels.
