Deploying Pico cell Base Station (PBS) throughout a Macro cell layout is a promising solution to enhance system capacity and users throughput. However, the strong received power from Macro cell Base Station (MBS) makes the Pico cell areas narrow and limits cell splitting gain. Range Expansion (RE) is desirable to balance the network load between MBS and PBS by expanding the coverage, which subsequently increases cell splitting gains. However, more interference may be introduced if the bias value of RE is not set properly. In this paper, we propose a Dynamic Cell Range Expansion (DCRE) strategy that the bias value of RE is set dynamically according to the change of network environment. The proposed scheme aims to fulfill the resources utilization by RE scheme, and meanwhile improve the users performance of cell edge through cell load balancing method. Simulation results show that DCRE scheme can improve the network performance of cell edge, and increase the cell capacity and users throughput compared with the existing methods.

Device-to-device communications refer to the emerging paradigm that permits direct communication between cellular users that are in close physical and social proximity. It is expected to become an essential aspect of the future 5G cellular communications system. As a prerequisite for device-to-device communications, a user has to select another user in its proximity that has the desired information/service and is willing to share it. In this paper, we propose a method for peer selection in dense small-cell device-to-device networks that uses multi-attribute decision modeling. The method exploits both the physical and social characteristics of the user equipment to find the most suitable peer for device-to-device communications. We assume hexagonal small-cell and macro-cell architectures with a small-cell/macro-cell base station with multiple user equipments in its coverage area to evaluate the proposed scheme’s performance. The small-/macro-cell base station exploits various social and physical attributes to rank peers and selects the best one for device-to-device communication with the requesting user. The numerical results demonstrate the proposed algorithm’s efficiency in terms of computational time, selection of the best peer, throughput, and energy efficiency of device-to-device communications.

They could be clearly passed on without requesting a focal expecting to pass on the high information speed orchestrate through aim perfect scope. The Femtocells are low power, actuallesser and cost in real cell base district utilized in the inside condition. Regardless, the impact of the Femtocells is the introduction of the straight Macrocell structure indications impediment issue among the Femtocells also earlier Macrocellsby strategy for they can part of the similar approved rehash run. The Frequency Reuse is a centrality of sending the rehash supply distribution upon station's place to recuperate framework limit. This paper, a fit strategy to develop structure restrict through inter vent ionorganization in the current Femto Macro 2layer systems has been planned. In the planned system, a original rehash saving for 2layersthe cell organizes by systems for rehash reuse technique is utilized wherever Macro base placesallot rehash sub-groups portrayed out for the Femtocells operators on demand based one the Femtocells base places toward stop impedance.

<div>This research focuses on the problem of cell edge user’s coverage in the context of femtocell networks operating within the locality of macrocell border where pathloss, shadowing, Rayleigh fading have been included into the environment. As macro cell edge users are located far-away from the macro base station (MBS), so that, the underprivileged users (cell edge users) get assisted by the cognitive-femto base station (FBS) to provide consistent quality of service (QoS). Considering various environment factors such as wall structure, number of walls, distance between MBS and users, interference effect (i.e., co-tier and cross-tier), we compute downlink (DL) throughput of femto user (FU) for single input single output (SISO) system over a particular sub-channel, but also based on spectrum allocation and power adaptation, performance</div><div>of two tier network is analyzed considering network coverage as the performance metric. Finally, the effectiveness of the scheme is verified by extensive matlab simulation.</div>
