“…Consequently, cross-layer designs able to jointly optimize the scheduling, ARQ, and AMC functions should be devised. Although many recent works focus on cross-layer designs that combine AMC schemes with ARQ error control protocols (see, e.g., [1][2][3][4][5][6][7][8][9][10][11][12]), proposals also incorporating the multiuser scheduling process at the media access control (MAC) sublayer are much less common (see, e.g., [13][14][15]). Liu et al in [15] presented an opportunistic scheduling scheme to improve the delay performance of secondary users with bursty traffic in cognitive radio (CR) systems.…”

“…The max-rate multiuser scheduler was included in the model through a service-vacation process allowing a manageable number of system states irrespective of the number of users sharing the channel. Nevertheless, the analysis in [14] suffers from an inaccurate modeling of the flat-fading wireless channel caused by the use of a first-order AFSMC (see [9][10][11][12] for an indepth discussion of this and related issues). Moreover, the approach in [14] does not define a cross-layering scheme as a means to optimize the system performance, and on top of this, users are assumed to operate in channels with equal characteristics, thus restricting the usefulness of the presented results.…”

This paper proposes a novel framework for the cross-layer design and optimization of wireless networks combining adaptive modulation and coding (AMC) at the physical (PHY) layer with automatic repeat request and channel-aware multiuser scheduling protocols at the data link control (DLC) layer. The proposed framework is based on the use of first-order two-dimensional discrete time Markov chains (DTMCs) jointly modeling the AMC scheme and the amplitude and rate of change of the wireless channel fading envelope. The behavior of the scheduler is embedded into the multidimensional PHY layer Markov model through the use of a service-vacation process. Using this PHY-media access control (MAC) Markov model, the quality of service performance at the DLC layer is discussed considering two different approaches. The first one relies on an analytical framework that is based on the multidimensional DTMC jointly describing the statistical behavior of the arrival process, the queuing system, and the PHY layer. The second one is rooted in the use of the effective bandwidth theory to model the packet arrival process and the effective capacity theory to model the PHY/MAC behavior. Both the DTMC-based and effective bandwidth/capacity-based approaches are analyzed and compared in a cross-layer design aiming at maximizing the average throughput of the system where constraints on the maximum tolerable average packet loss and delay are to be fulfilled.

“…The finite-state Markov channel (FSMC) model has been widely used for modeling wireless channels [13] [14]. A wide range of FSMC applications in performance evaluation of wireless networks can be found in the literature, e.g., [15] [16]. This paper adopts the finitestate Markov model (FSMM) to reflect the service rate of the single-input multiple-output (SIMO) and VMIMO channels.…”

With the advent of small cell networks (SCNs) to support growing wireless data volumes and thus reduced cell sizes, cooperative communications are significantly facilitated. Applicable to 3GPP LTE-A, we propose a novel channel/queue-aware user pairing and scheduling scheme in a cooperative virtual multiple-input multiple-output (VMIMO) system. The queueing performance of the VMIMO system with the scheduling scheme is analyzed based on the finite-state Markov model (FSMM), and compared with that of non-cooperative systems. Bounds on the average queuing delay of users are derived by using a semi-definite programming (SDP) approach. The presented analyses are validated through comparing the analytical and simulation results. It is found that the introduced VMIMO pairing process is able to significantly reduce service delays, bringing on a positive impact of cooperative techniques on next generation wireless systems.

“…By employing adaptive modulation coding (AMC) at physical layer and automatic repeat request (ARQ) or Hybrid ARQ (HARQ) at data link layer, the system could achieve a considerable gain in spectral efficiency or reduce the packet loss rate [5][6][7][8]. This is due to the fact that by adopting retransmission protocol to guarantee the information transmission, cross-layer design could allow for higher and more efficient transmission mode.…”

In this paper, we propose a cross-layer design combining adaptive modulation coding (AMC) and automatic repeat request (ARQ) to minimize the bit energy consumption under both packet loss rate and retransmission delay constraints. We analyze the best constellation size of M-ary square quadrature amplitude modulation (MQAM) in different distance, and give advice on retransmission limits under different packet loss rates. The impacts of path loss fading and additive white Gaussian noise (AWGN) are taken into consideration. The computation of energy consumption includes the circuit, transmission and retransmission energies at both transmitter and receiver sides. Numerical results are obtained to verify the validity of our design. We also show that the retransmission benefit varies with the packet loss rate constraint.
