Abstract
In this paper we investigate the potential of downlink frequency-domain packet scheduling (FDPS) for the 3GPP UTRAN long term evolution. Utilizing frequency-domain channel quality reports, the scheduler flexibly multiplexes users on different portions of the system bandwidth. Compared to frequency-blind, but time-opportunistic scheduling, FDPS shows gain in both average system capacity and cell-edge data rates on the order of 40%. However, FDPS performance is shown to depend significantly on the frequency-domain scheduling resolution as well as the accuracy of the channel state reports. Assuming Typical Urban channel profile, studies show that the scheduling resolution should preferably be as low as 375 kHz to yield significant FDPS gain and the std. of the error of radio state reports need to be kept within 1.5-2 dB.
