Abstract: Uplink scheduling in OFDMA systems with imperfect CSI is investigated. An efficient CSI quantization scheme is proposed and shown to achieve good performance with a limited number of quantization bits in the perfect CSI scenario. The probability of error in quantizing imperfect CSI is studied and analytical formulas are derived. Simulation results are presented and show that the errors in estimating the CSI are to a large extent absorbed by the quantization error and the performance with quantized imperfect CSI is close to full CSI even with a reduced number of quantization bits.
