Rate Regions for Coordination of Decode-and-Forward Relays and Direct Users
Recently, the ideas of wireless Network Coding (NC) has significantly enriched the area of wireless cooperation/ relaying. They bring substantial gains in spectral efficiency mainly in scenarios with two - way relaying. Inspired by the ideas of wireless NC, recently the authors have proposed techniques for Coordinated Direct/Relay (CDR) transmissions. Leveraging on the fact that the interference can be subsequently canceled, these techniques embrace the interference among the communication flows to/from direct and relayed users. Hence, by allowing simultaneous transmissions, spectral efficiency is increased.
