“…In order to palliate this, Long Term Evolution (LTE) Release 10 introduced enhanced mechanisms for Intercell Interference Coordination (eICIC) that allow for SINR enhancement, though at the cost of reducing macrocell capacity. These techniques are mostly variations of the same idea: frame muting and coordinated scheduling [2].…”

This paper provides new insights into the performance of Uplink and Downlink Splitting (UDS) in highly loaded wireless communication systems, in terms of both serving nodes and the number of users with high traffic activity. The study puts special focus on the gains that UDS could bring in terms of SINR and throughput when compared with systems with cell range expansion (CRE) in the classic downlink based cell association. CRE not only helps to offload users from macro-to pico-eNBs, but also improves UL service. Instead of an aggregated throughput analysis, a detailed classification of users is performed to figure out the causes of users' gain or loss after applying each strategy at the system level. Results show marginal gains of a pure path loss based UDS when compared with the intrinsic UL gains of CRE. Given the extra flexibility in radio resource management that splitting both links could bring, using an individual UL adjustable cell offset appears to be an interesting strategy to allow for a finer control of UL interference. The dependency of UDS performance with small cell density has also been a matter of study. Results show that the gains of UDS do decrease after a certain density of pico-cells is surpassed.

“…A typical HetNet approach is to place a pico cell within the coverage area of a macro cell with the purpose of allowing user equipment (UE) to access pico cells with overlapping geographical coverage areas. Cell range expansion (CRE) technology, which encourages the data traffic movement of macro cell to a pico cell, may significantly assist HetNet deployment [3,4]. For a HetNet approach to be effective, it is important to determine whether UE should communicate with macro cells or pico cells.…”

Performance evaluation of adaptive control CRE in HetNet with eICIC scheme

This paper describes the performance evaluation of a state-ofthe-art adaptive control cell range expansion (CRE) technique in Heterogeneous Network (HetNet) with enhanced inter-cell interference coordination (eICIC) scheme. The features of the proposed adaptive control CRE technique are described through comparison with those of conventional methods. System-level computer simulation results such as average and 5-percentile user throughput are provided under the conditions of HetNet with eICIC, as parameters of almost blank subframe (ABS) ratio for eICIC. We confirmed that the proposed adaptive control CRE can improve 5-percentile user throughput while maintaining the average user throughput even for HetNet with eICIC.

“…The number of sub frame to be blanked was dependent on the number of victim users and normal users who are not interfered by the aggressor node. [18] solve the coupled problems of: (i) determining the amount of radio resources that macro cells should offer to pico-cells and (ii) determining the association rules that decide which user equipment should associate with pico cell. Cell Selection Biasing (CSB) was used to determine user association, while the amount of radio resources was determine using ABS.…”

The deployment of small cell node such as femto-cell within macro area coverage has been considered a promising solution to provide better throughput and Quality of Experience (QoE) to users. However, co-channel deployment of femto-cell operating in a closed access mode (CSG) causes severe cross-tier interference. In this paper we have develop an adaptive Hybrid Power control and Time domain Technique (aHPTT) to mitigate cross-tier interference in HetNet. The hybrid technique was developed to handle limitations associated with using a single interference mitigation technique such as Power Control (PC) and Time Domain (TD). aHPTT integrate PC and TD to mitigate interference simultaneously depending on the position of the user in the network. The hybrid technique was implemented in a Graphical User Interface (GUI) using MATLAB R2013a. System level simulation was carried out to evaluate the performance of the hybrid technique in terms of user's throughput. The aHPTT was validated with the 3 rd Generation Partnership Project (3GPP) enhance Inter-cell Interference Coordination (eICIC) technique, results obtained showed that the aHPTT performs better than PC technique by 2.90% and TD technique by 82.60%.
