CSI feedback in OFDMA wireless networks with multiple transmitter-receiver pairs


In wireless systems, multiple transmitters often need to deliver data to multiple receivers in the same interference domain. OFDMA enables interference avoidance by assigning disjoint sets of subcarriers to each transmitter. However, optimal subcarrier allocation requires CSI feedback to the transmitters, thus incurring overhead. We evaluate an allocation… (More)
