Abstract

In this paper, we propose a new packet scheduling algorithm to support the real-time video traffic in WCDMA downlink. Accumulation counter is introduced as a new priority metric to determine the transmission priority among several data users.We consider a two-dimensional transmission structure of using both the frame period in the time-axis and the OVSF codes in the code-axis at the same time, which is similar to a fast packet scheduling concept in the emerging high speed downlink packet access (HSDPA) speciffication of WCDMA system. Simulation results show that the proposed approach provides an excellent delay performance as compared with conventional algorithm for real-time video traffic.
