“…Secondly, most of the former studies commonly assumed that the lost packets are retransmitted immediately in the very next timeslot [19]- [22]. This is a very strong assumption because the time consumed by data decoding, processing, and feedback is not negligible when the round-trip time is considered.…”

Abstract-This paper proposes an efficient yet simple design framework for achieving flexible resource allocation and packet scheduling for non-real-time polling service (nrtPS) traffic in IEEE 802.16 networks. By jointly considering the selective Automatic Repeat reQuest mechanism at the media access control layer as well as the adaptive modulation and coding technique at the physical layer, the proposed framework enables a graceful tradeoff between resource utilization and packet delivery delay while maintaining the minimum throughput requirements of nrtPS applications. An analytical model is developed for parameter manipulation in the proposed framework, where some important performance metrics, such as inter-service time, delivery delay, goodput, and resource utilization, are investigated for performance evaluation. Simulation results are given to demonstrate the efficiency of the proposed framework and verify the accuracy of the analytical model.

“…Secondly, the previous studies commonly assumed that the lost protocol data units (PDUs) are retransmitted in the very next timeslot [3][4][5][6][7][8][9][10]. The analysis of service data unit (SDU) delivery delay for IEEE 802.16 networks discussed [11] is also based on the assumption that the lost PDUs were retransmitted immediately in the next frame. The assumption of immediate retransmission is a strong assumption because the time consumed by data decoding, processing, and feedback is not negligible and the round-trip time should be considered.…”

In this paper, we study the performance of the cumulative Automatic Repeat reQuest (ARQ) in IEEE 802.16 networks. An analytical model is developed to investigate some important performance metrics, such as protocol data unit (PDU) delivery delay, service data unit (SDU) delivery delay, and goodput. A general scheduling scheme and the flexible retransmission of lost PDUs are jointly considered in the analytical model, which provides a more valuable and practical guideline for the system design and performance evaluation. Extensive simulations are conducted to demonstrate the impacts of different operational parameters on the performance metrics and verify the accuracy of the analytical model.

In the 4G communications standards, including Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution (LTE), Automatic Repeat reQuest (ARQ) is one of the important tools to coop with error-prone transmission environments. The primary function of ARQ is to provide reliable communication between a transmitter and its receivers through the retransmission of lost ARQ blocks. The retransmission at the sender can be triggered by either of the two events. The first one is for the sender to retransmit an ARQ block whose retry timer expires. The second one is when the transmitter receives the feedback message reports, which indicate block reception situation from the receiver, the flagged lost ARQ blocks will then be sent again. There are four types of feedback messages defined in the WiMAX standard. How and when the receiver reports feedback messages will have impact on the transmission efficiency. If the receiver reports feedback messages more frequently, the lost ARQ blocks can be retransmitted more promptly at the cost of higher bandwidth consumption of the feedback channel. By contrast, if the receiver waits for a longer time before sending a feedback message, feedback messages can be formed more efficiently in terms of bandwidth usage with longer transmission time incurred. In this paper, a performance evaluation metric is defined to consider the influence of both transmission latency and the required bandwidth to transmit feedback messages. A feedback message transmission scheme is further proposed to determine the interval and the types of feedback messages dynamically, based on the condition of channel conditions. The proposed method is aimed to find a balance between the transmission delay and the bandwidth usage efficiently, and the improvement of the proposed method is confirmed by the experiment results.
