我们考虑两个用户状态相关的多路访问信道，其中只有一个编码器非因果地获知信道状态。传输两个独立的消息：由通知编码器和非通知编码器传输的公共消息，以及仅由非通知编码器传输的单独消息。我们在离散无记忆情况以及高斯情况下推导了该模型容量区域的内界和外界。此外，我们表明，在某些特殊情况下，高斯情况的界限是严格的。
We consider a two-user state-dependent multiaccess channel in which only one of the encoders is informed, non-causally, of the channel states. Two independent messages are transmitted: a common message transmitted by both the informed and uninformed encoders, and an individual message transmitted by only the uninformed encoder. We derive inner and outer bounds on the capacity region of this model in the discrete memoryless case as well as the Gaussian case. Further, we show that the bounds for the Gaussian case are tight in some special cases.
