Abstract :
UTRAN Long Term Evolution (LTE), marked as 4G LTE, is a standard for wireless communication developed by 3GPP, which is aiming to provide a spectral efficiency 2 to 4 times higher than its predecessor HSUPA/HSDPA Release 6. As an uplink access scheme for LTE, the Single-Carrier Frequency Division Multiple Access (SC-FDMA) technology has to allocate continuous resources to one single-user, so this limitation will reduce the allocation flexibility and bring more challenges to design an effective packet scheduling algorithms. In this paper, we propose a new algorithm, named as Adaptive Resource Allocation Based Packet Scheduling (ARABPS) algorithm, which can allocate resources to a single-user flexibly as possible as we can. The simulation result indicated two major conclusions: one is that the ARABPS algorithm in this paper could gain 35% ~ 75% throughput than the Roundup Robin algorithm and the other is that the ARABPS could provide the better fairness relative to the Max C/I algorithm.
