“…For non-real-time applications, the transmission throughput is the main index for performance evaluation because there is no specific QoS requirements. While for real-time applications such as voice and video, the average delay, delay violation probability and loss probability are the QoS metrics for packet scheduling [8][9]. From a network architecture point of view, the current DSA algorithms are mainly based on the strictly layered structure due to its easy implementation in practice.…”

In this paper, an improved utility-based cross-layer dynamic subcarrier allocation (DSA) algorithm is proposed for single carrier frequency division multiple access (SC-FDMA) system, which adopts adaptive service rate control (ASRC) to eliminate the service rate waste and improve the spectral efficiency in heterogeneous network including non-real-time traffic and real-time traffic. In this algorithm, furthermore, a first in first out (FIFO) queuing model with finite space is established on the cross-layer scheduling framework. Simulation results indicate that by taking the service rate constraint as the necessary condition for optimality, the ASRC algorithm can effectively eliminate the service rate waste without compromising the scheduling performance. Moreover, the ASRC algorithm is able to further improve the quality of service (QoS) performance and transmission throughput by contributing an attractive performance trade-off between real-time and non-real-time applications.
