Partial Channel Quality Information Feedback in Multiuser Relay Networks Over Nakagami-m Fading

Lu, Yao; Yang, Nan; Elkashlan, Maged; Yuan, Jinhong


We propose a new partial feedback scheme in multiuser relay networks (MRNs) where a source communicates with K destinations via a relay. We focus on a practical network model where orthogonal frequency division multiple access (OFDMA) is adopted in the downlink and only limited feedback overhead is supported in the uplink. For this model, we consider that the OFDMA spectrum consists of MRB resource blocks (RBs). In the proposed scheme, the destinations feed back the channel...[Show more]
