The multi-way relay channel is a fundamental building block for the relay networks with multicast transmission. General multi-way relay channel that consists of a relay and L clusters of users with N users in each cluster. The users in each cluster are interested in exchanging information from other users in the same cluster. It is assumed that the users cannot directly communicate with each other, and thus the users in each cluster can only exchange information with the help of the relay. This fundamental model characterizes many interesting practical communication scenarios. For example, in ad hoc networks, wireless nodes can be geographically separated, yet they can communicate to a central controller to share information.
