An Amplify-and-Forward Full-duplex Cooperative Relay Scheme for Low-latency Downlink Transmission in CRAN

This letter proposes a novel full-duplex-enabled cooperative relay scheme to reduce the downlink delivery latency in cloud radio access networks (CRAN). Specifically, remote radio heads (RRHs) are deployed with full-duplex capability and work in Amplify-and-Forward mode so that they could receive signals from the baseband signal processing unit (BBU) and forward to the user groups immediately, whi...
