“…Since computation complexities increase with number of individual subcarriers to be allocated, it may be potentially helpful to allocate the subcarriers in chunks or blocks to reduce complexity. In [60], [61] and references therein, it was shown that chunk-based contiguous subcarrier allocation method based on SNR or BER constraints can effectively mitigate complexities and overheads. However, as expected, one major drawback of this approach is how to combat frequency selective fading on some subcarriers within the chunk which may hamper the possible benefits of chunk allocation.…”

Multicasting is emerging as an enabling technology for multimedia transmissions over wireless networks to support several groups of users with flexible quality of service (QoS) requirements. Although multicast has huge potential to push the limits of next generation communication systems; it is however one of the most challenging issues currently being addressed. In this survey, we explain multicast group formation and various forms of group rate determination approaches. We also provide a systematic review of recent channel-aware multicast scheduling and resource allocation (MSRA) techniques proposed for downlink multicast services in OFDMA based systems. We study these enabling algorithms, evaluate their core characteristics, limitations and classify them using multidimensional matrix. We cohesively review the algorithms in terms of their throughput maximization, fairness considerations, performance complexities, multi-antenna support, optimality and simplifying assumptions. We discuss existing standards employing multicasting and further highlight some potential research opportunities in multicast systems.

“…To further reduce complexity in practice, the algorithm may be modified to operate on a subchannel consisting of adjacent subcarriers with approximately similar channel gains rather than on individual subcarriers. Such approach has been considered in OFDMA resource allocation, e.g., in [13], [14].…”

Abstract-Orthogonal multicarrier division duplexing (MDD)is a new duplexing scheme that gains the advantages of both time division duplexing and frequency division duplexing. Resource allocation for multipoint-to-multipoint (M2M) MDD is considered in this paper. We propose joint subcarrier and power allocation for M2M MDD that maximizes the sum rate of the network under either total or individual power constraint. Simulation results show that MDD outperforms conventional TDD and TDD-OFDMA systems. Some insights on M2M MDD under different channel conditions are given and convergence of the proposed algorithm is shown through simulation results.

“…For the conventional orthogonal frequency division multiplexing (OFDM) system, the resource allocation and scheduling schemes have been studied extensively [4]- [6]. However, none of these has considered the impact of relay on the system performance.…”

In this paper, we propose a novel downlink radio resource management scheme for a User Equipment (UE)-Relay enhanced downlink heterogeneous network. An optimal region and frequency division scheme with Fraction Frequency Reuse (FFR) is proposed to cancel the interference between the eNodeB (eNB)-Relay Station (RS) link and the RS-UE link. Moreover, a novel radio resource management scheme is designed to improve the network throughput. The proposed optimization framework jointly considers the region division parameter and the frequency division parameter. The Lagrange dual function is derived for the proposed optimization problem, and the gradient descent method is used to find out the optimal solution for the convex dual problem. Simulation results show that both the data rate of cell-edge UEs and the number of satisfied UEs can be greatly increased. Keywords-UE-Relay;convex optimization; fractional frequency reuse; radio resource management I.
