This paper deals with the description of the QoS architecture developed in the framework of the IST VIRTUOUS and SAILOR projects, especially targeting at the design of an UMTS MAC scheduling algorithm in charge of managing several uplink parallel active logical channels at User Equipment side. The joined approach to the packet scheduling and transport format choice proposed in this paper shows better performances respect to the 3GPP standard solution, mainly when the number of logical channels of different types --- i.e. logical channels with different needs in terms of maximum allowed delay --- handled by the same User Equipment increases. Furthermore, the proposed MAC design introduced in this paper allows a better exploitation of the available bandwidth in the uplink UMTS Radio Access Network, also increasing fairness between IP datagrams belonging to different sources.
