“…The downlink channel in LTE adopts OFDMA as an access technology. This allows empowering the system with many features, for example, enormous transmission rates, scalable and efficient bandwidth planning, and high consistency against multi-path fading [31]. According to OFDMA channel model in LTE Release 10 [32], a wide range of radio spectrum up to 20 MHz is supported, which allows a high order of available radio resources to carry user's data.…”

Guaranteeing Quality of Service (QoS) for heterogeneous traffic is a major challenge in the Fourth Generation (4G) mobile networks. Therein, the absence of sophisticated resources allocation process at the base station jeopardizes QoS in terms of latency data transfer. It has been observed from the literature that low delay bounds might be ensured, however, at the expense of other QoS aspects; for example, throughput and data loss. Therefore, in this article, we propose an effective Delay-based and QoS-Aware Scheduling (DQAS) scheme with a low complexity overhead as an efficient solution for the resource allocation issue in LTE Medium Access Control (MAC) layer. The ultimate aim of DQAS is to minimize delay for Real-Time (RT) traffic while still offering a good level of QoS. Complying with QoS of different traffic types, we effectively analyze the queue buffer of each user flow by developing an algorithm called Efficient Delay Control (EDC) that weights each flow priority in terms of delay. Then, this weight is utilized as a principle for the scheduling decision on the attending flows. Furthermore, the Least Delay Increase (LDI) algorithm is developed to tune the scheduler behavior to maintain a balance between delay and system throughput. Simulation results considering different user mobility levels reveal that DQAS significantly guarantees a low end-to-end delay trend that is independent of increased RT load, and moreover, a reasonable throughput and data drop levels compared to other existing schedulers.

“…For JP scheduling technique, ICI can significantly be mitigated by applying the signals transmitted from other eNBs to assist the transmission on the same physical resources to provide constructive interference at the UE [17,18,30]. This will make the communication overhead still affordable among the eNBs.…”

This paper provides a review of current technology components currently used by OFDMA-based Long Term Evolution-Advanced (LTE-Advanced). LTE-Advanced significantly enhanced the previous versions of LTE Release 8/9 to support higher data rates and wider coverage resulting in best experience for users. Some of the technologies discussed in this paper are enhanced Multiple Input Multiple Output (MIMO), advanced repeaters or known as relaying systems, coordinated multipoint transmission/reception and carrier aggregation to expand the capability of the bandwidth spectrum. Among the issues addressed in this paper are related to balancing of transmit power control for both base stations and relay stations and also frequency spectrum allocation in order to avoid any interference within a mobile cell. This also includes how to manage different types of interferences such as intercell interference, intersymbol and intercarrier interferences in the LTE-Advanced system.

With the extensive proliferation of mobile applications and smartphones, there is an increasing trend of technical adoption of 3G (third generation). But, with the exponential growing of massive traffic, it is seen that even 3G network is completely not capable of catering to the dynamic needs of the customers. This paper focuses on the usage of 4G-LTE (fourth generation-long term evolution) network that has higher support for heterogeneous network access catering to the needs. 4G-LTE is designed on the principles of packet switching system on the backbone of IP protocol. This paper presents a review on the state-of-art techniques from the viewpoint of mobility management approach, which is highly enriched with informative contents compared to existing reviews.
