The concept of bidirectional relaying is a key technique to improve the performance in future wireless networks. It applies to three-node networks, where a relay node establishes a bidirectional communication between two other nodes using a decode-and-forward protocol. It divides the whole communication into two phases, namely the multiple access and bidirectional broadcast phase. Here, we concentrate on the second phase, which is also known as the bidirectional broadcast channel, and assume that the transmission is affected by arbitrarily varying channels. We impose constraints on the permissible input and state sequences and derive the capacity regions for random and deterministic coding.
