Motivated by the cellular uplink scenario along with the increasing capabilities of radio nodes, we consider a state-dependent multiple-access channel in which the encoders can overhear other transmissions while simultaneously sending their own transmissions. In addition, the channel is state dependent and encoders have access to independent causal state information while the decoder has complete state information. We characterize the capacity region of this setup. The encoders in our achievability scheme make full use of the partial cribbing resources by jointly mapping the cribbed sequences and cooperatively forwarding the information to the decoder, without attempting to explicitly recover any part of the other encoder's message or state information.
