Opportunistic Scheduling in a Bidirectional Communication Link with Relaying

In this paper we study transmission scheduling in a bidirectional communication link, where two end nodes are communicating with each other through a relay node. Each of the two end nodes injects data into a separate buffer at the relay node, which can either forward the data from one end node to the other at a given time (referred to as one-way relay), or simultaneously forwarding the data to both the end nodes by using network coding …
