Two protocols, i.e., \\emph{Simultaneous} and \\emph{Successive} relaying, associated with two possible relay orderings are proposed. The simultaneous relaying protocol is based on \\emph{Dynamic Decode and Forward (DDF)} scheme. For the successive relaying protocol: (i) a \\emph{Non-Cooperative} scheme based on the \\emph{Dirty Paper Coding (DPC)}, and (ii) a \\emph{Cooperative} scheme based on the \\emph{Block Markov Encoding (BME)} are considered.
