heal.abstract	Enhanced Uplink operation of WCDMA-UMTS systems utilizes fast Node B scheduling and a short Transmission Time Interval (TTI) of 2ms. The scheduling decisions are based on scheduling information (SI) sent by each UE to the Node B.The main drawback of the current scheduling procedure is that the SI does not include any information regarding the delay sensitivity of each traffic flow, as well as the actual delay that the buffered data have experienced. In this paper, we propose the inclusion of such information in SI by introducing a modification of the respective 3GPP specifications. Furthermore, we propose a Dynamic Priority Scheduler (DPS), which can utilize this new information. The performance of the proposed scheme is evaluated by means of system level simulations.	en
