“…Several papers in the literature explain practical considerations to achieve desired performance levels in networks, such as deployment options, implementation frameworks, and challenges in the physical layer [6][7][8]. The work by Shen et al [15] provides an overview on all layers, while also underlining the interest of several major U.S. providers in the technology.…”

Abstract-A recent policy ruling by the Federal Communications Commission (FCC) set aside a fixed amount of cleared spectrum for smaller network providers. Thanks to this ruling, smaller providers can improve their quality of service using carrier aggregation. In this paper, we determine the optimal (minimum) level of carrier aggregation that a smaller provider needs in order to bring its service in line with a larger provider in the same market. Toward this end, we provide an asymptotically exact formula for the loss (blocking) probability of flows under a quality-driven (QD) regime. Using this formula, we establish an efficient way of numerically calculating the optimal level of carrier aggregation and derive scaling laws. Specifically, we show that the optimal level of carrier aggregation scales sub-linearly with respect to the scaling factor, i.e., the ratio between the network capacities of the two providers, and decreases with the initial traffic load of the providers. We derive a closed-form linear upper bound on the optimal level of carrier aggregation and prove that it is the tightest possible. We provide numerical results, showing the accuracy of our methods and illustrating their use. We also discuss the extension of our results to delayrelated metrics as well as their application to profitable pricing in secondary spectrum markets.

“…The policy ruling is facilitated by a central feature of LTE-Advanced networks (as defined in 3GPP Release 10 and beyond) called carrier aggregation [6][7][8][9]. Carrier aggregation allows service providers to aggregate contiguous or non-contiguous component carriers up to 100 MHz total bandwidth.…”

Long Term Evolution Advanced (LTE-Advanced) is the next step in LTE evolution and allows operators to improve network performance and service capabilities through smooth deployment of new techniques and technologies. LTE-Advanced uses some new features on top of the existing LTE standards to provide better user experience and higher throughputs. Some of the most significant features introduced in LTE-Advanced are carrier aggregation, enhancements in heterogeneous networks, coordinated multipoint transmission and reception, enhanced Multiple Input Multiple Output (MIMO) usage and deployment of relay nodes in the radio network. Mentioned features are mainly aimed to enhance the radio access part of the cellular networks. This survey article presents an overview of the key radio access features and functionalities of the LTE-Advanced radio access network, supported by the simulation results. We also provide a detailed review of the literature together with a very rich list of the references for each of the features. An LTE-Advanced roadmap and the latest updates and trends in LTE markets are also presented.

“…This scenario can be expected in countries where spectrum allocation is noncontiguous within a single band, when the middle carriers are loaded with other users, or when network sharing is considered. Therefore this model would fit operators in North America or Europe, who have fragmental spectrum in one band or share the same cellular network [5].…”

The aim of this paper is to discuss the development of LTE algorithm which has the most advantages compare to other technologies such as WiMAX and WiFi. In order to improve LTE disadvantages is to increase the bandwidth at both sides (transmitter and receiver), where the current bandwidth is 100 MHz and the peak data rate is 1Gpbs. The objective of this paper is to increase the bandwidth up to 100 MHz through increasing the number of carrier aggregation in LTE system. This paper focus on the high-bandwidth internet access anytime, anywhere which is continuously increasing. As the spectrum is limited, this means mobile communications systems have to support larger bandwidth than today's systems. Peak data rates up to 1 Gbps are expected from bandwidths of 100 MHz where OFDM adds additional subcarrier to increase bandwidth. Unfortunately, the available bandwidth may not be continuous as a result of fragmented spectrum. In addition, this feature allows scalable expansion of effective bandwidth delivered to a user terminal through concurrent utilization of radio resources across multiple carriers. Therefore, in order to support bandwidths greater than 20 MHz, two or more component carriers (CCs) (of the same or different bandwidths) are aggregated together in LTE-A. This way, wider transmission bandwidths are supported in the downlink (DL) or uplink (UL) between User equipment (UE) and Evolved Node B (eNB).
