Title :
Sounding subband allocation algorithm for proportional fair scheduling in OFDMA/FDD uplink
Abstract :
A sounding subband allocation algorithm is proposed for a proportional fair (PF) scheduler in an OFDMA/FDD uplink. The proposed sounding algorithm tries to provide a PF scheduler with more proper channel state information of multiple users by using an estimated PF metric. It is shown that the proposed sounding subband allocation algorithm enables the PF scheduler to achieve the throughput gain and guarantee fairness at the same time
