Abstract :
We consider the problem of communicating degraded message sets over multi-access channel with finite input and output alphabets that is controlled by an underlying i.i.d. state process. Inner and outer bounds are presented for the general case where encoders possess non-causal degraded state information. Two special cases of the general setup are then presented where the derived inner bound is shown to be the capacity region.
