In this paper we study a utility based optimized cross-layer multiuser scheduling for real-time video transmission over HSDPA. The utility here refers to the packet utility which is defined as a function of the packet urgency and the packet importance. Transmitting the packets with greater utility values firstly in each TTI can provide a higher level of satisfaction (video quality) for the users....
With the growing popularity of video applications, the provision of high-quality video transmission for multi-users over High Speed Downlink Packet Access ( HSDPA ) networks gradually becomes a research focus. In HSDPA, the downlink shared channel is shared among the users to transmit packets. Hence, the packet scheduling algorithms play an important role in the HSDPA system performance. In this paper,...
