Abstract
We consider the problem of reliable communication over multiple-access channels (MAC) where the channel is driven by an independent and identically distributed state process and the encoders and the decoder are provided with various degrees of asymmetric (noisy or partial) channel state information (CSI). Namely, we provide a single letter characterization for the capacity region when the encoders have access to non-causal asymmetric partial CSI and the decoder has complete CSI. When the encoders observe asymmetric noisy CSI with asymmetric delays and the decoder observes complete CSI, we provide a single letter characterization for the capacity region. Finally, we consider a cooperative scenario with common and private messages, with... (More)

Namely, we provide a single letter characterization for the capacity region when the encoders have access to non-causal asymmetric partial CSI and the decoder has complete CSI. When the encoders observe asymmetric noisy CSI with asymmetric delays and the decoder observes complete CSI, we provide a single letter characterization for the capacity region. Finally, we consider a cooperative scenario with common and private messages, with noisy CSIT and complete CSIR and provide a single letter expression for the capacity region. For the cooperative scenario, we also note that as soon as the common message encoder does not have access to CSI, then for any noisy CSIT and CSIR setup it is possible to obtain a single letter characterization for the capacity region.
