“…Some studies consider LTE HetNets with the coexistence of macro-cells and pico-cells. Specifically, the work of [20] determines the location, transmission power, and antenna tilt of each pico-cell eNB with the help of CRE (cell range expansion) and TDM-ICIC (time domain multiplexing inter-cell interference coordination) techniques, which can balance macrocell eNBs' loads and mitigate their interference, respectively. Barbera et al [3] evaluate the effect of different pico-cell eNB deployment and user mobility patterns on UE handover between LTE cells.…”

a b s t r a c tBase station deployment is an important issue in cellular communication systems because it determines the cost to construct and maintain a system and also the service quality to users. Conventional 2G and 3G systems assume that base stations are identical in the sense that they have the similar coverage range. For 4G systems, LTE introduces the concept of heterogeneous base stations (also called eNBs), which supports different sizes of coverage range. Given the user distribution and demands in a service area, the problem of deploying heterogeneous eNBs is NP-hard. Therefore, we propose a four-stage eNB deployment strategy to efficiently solve the problem. Our strategy first employs a geometric approach to provide the basic coverage to the service area. Then, it adaptively adjusts the cell range to satisfy the user demands under the power and bandwidth constraints on each eNB. Simulation results verify that the proposed strategy not only significantly saves the system cost, but also reduces the power consumption while balances the traffic loads of eNBs.

“…Release 10 has come up with solutions to solve mentioned issues through a feature called enhanced Inter Cell Interference Coordination (eICIC), also referred to as Time Division Multiplexing ICIC (TDM-ICIC) [102,129,130]. In this feature, macro and small cells are coordinated in the time domain and inter cell interference is avoided by preventing simultaneous transmission.…”

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.

“…However, femto-cell BSs are consumer-installed for private use. Given the locations of macro-cell BSs, [15] employs the CRE (cell range expansion) and TDM-ICIC (time domain multiplexing inter-cell interference coordination) technology to decide the positions, transmission power, and antenna tilt of pico-cell BSs. In this way, these pico-cell BSs may balance macro-cell BSs' loads and mitigate their interference.…”

In cellular networks, base station placement is a critical issue because it determines the construction cost and service quality. Existing placement approaches for 2G and 3G networks usually consider homogeneous base stations, where they have similar coverage areas and hardware features. Recently, the burgeoning LTE technology allows different types of base stations to collaboratively provide service in the same network. This characteristic motivates us to address the problem of placing heterogeneous base stations to serve user devices such that the overall cost is minimized while user demands are stratified. The problem is NP-hard, and thus we develop an efficient two-phase heuristic which first employs a geometric idea to provide coverage to all user devices and then adjusts the cell range to meet the power and bandwidth constraints of each base station. Experimental results show that our two-phase heuristic can reduce the construction cost and energy consumption of base stations.
