One of the most important features of HSPA is packet scheduling. The main goal of packet scheduling is to maximize the system throughput while satisfying the QoS requirements of the users. In this article I provide an insight into how this feature is performed in HSPA. The packet scheduler determines which user the shared channel transmission should be assigned to at a given time. In HSDPA, the packet scheduler can exploit the short-term variations in the radio conditions of different users by selecting those with favorable instantaneous channel conditions for transmission, as illustrated in the figure below; CONTINUE READING AT: http://trends-in-telecoms.blogspot.com/2011/03/hspa-packet-scheduling-insight.html
