Scheduling algorithms for HS-DSCH in a WCDMA mixed traffic scenario

Several scheduling algorithms are evaluated for the HS-DSCH channel in a WCDMA mixed traffic scenario. The traffic consists of FTP and Web surfing users. The maximum channel quality indicator (CQI) scheme serves users with the highest channel quality. The proportional fairness (PF) scheme tends to be fairer by prioritising users with higher channel quality (lower throughput). The weighted-queue-PF prioritises users with higher channel quality, lower throughput and those with longer queued-time. The results depict that the maximum system throughput is achieved by max CQI scheduling, which is pinch channel dependent. The max CQI scheme is also relatively fair to the FTP users. In case of Web surfing users, the proportionally fair scheduling is as good as the other schemes for the 10% worst users.
