“…1 [7]. Since these static clustering CoMP systems cannot eliminate cluster edges, dynamic clustering CoMP technique was proposed which adaptively changes cooperative clustering patterns per resource block [9]. However, dynamic clustering CoMP requires many types of clustering patterns to cover all cluster edges.…”

“…Even with this sectorization, there are still sector edge users with degraded user rate due to intersite interference and pathloss effect. In order to alleviate these sector edge users, inter-site CoMP with dynamic clustering which adaptively changes cooperative clustering patterns per resource block was proposed [8] [9]. However, this scheme requires a complicated backhaul network structure thus is unfeasible with current network technologies.…”

In conventional studies on Coordinated Multi-Point (CoMP) cellular networks, dynamic clustering schemes have been introduced to achieve CoMP gain at all cell edges. However, such schemes increase complexity of the network drastically and are unfeasible in the current network topology. In this paper, small power basestations (BSs) are introduced instead of dynamic clustering to solve cluster edge problem in CoMP cellular networks. This new cell topology is called diamond cellular network since the created cell structure is similar with diamond pattern. We derive optimal locations of small power basestations and optimal resource allocation between the CoMP basestation and small power basestations for the diamond cellular network. By using the proposed architecture, more than 250% improvement of 5% outage throughput is achieved compared with conventional single cell networks.

“…An algorithm was developed in Reference [8] in order to optimise the number of RRUs deployed in a network using game theory. Multipoint transmission coordination of distributed RRUs has been investigated in References [9,10]. While the first investigation on using remote antennas in the mmWave band was introduced in Reference [11], where the author has demonstrated the importance of remote antennas on minimising the shadow fading of wireless networks in the Local Multipoint Distribution Service (LMDS) band.…”

Abstract:In the Fifth Generation (5G) wireless standard, the Internet of Things (IoT) will interconnect billions of Machine Type Communications (MTC) devices. Fixed and mobile wearable devices and sensors are expected to contribute to the majority of IoT traffic. MTC device mobility has been considered with three speeds, namely zero (fixed) and medium and high speeds of 30 and 100 kmph. Different values for device mobility are used to simulate the impact of device mobility on MTC traffic. This work demonstrates the gain of using distributed antennas on MTC traffic in terms of spectral efficiency and fairness among MTC devices, which affects the number of devices that can be successfully connected. The mutual use of Distributed Base Stations (DBS) with Remote Radio Units (RRU) and the adoption of the millimetre wave band, particularly in the 26 GHz range, have been considered the key enabling technologies for addressing MTC traffic growth. An algorithm has been set to schedule this type of traffic and to show whether MTC devices completed their traffic upload or failed to reach the margin. The gains of the new architecture have been demonstrated in terms of spectral efficiency, data throughput and the fairness index.

“…In [4] the authors have developed an algorithm to optimise the number of deployed RRHs based on game theory. The use of beamforming and cooperation multipoint (CoMP) among deployed RRHs has been studied in [5] and [6]. Whereas in [7] a dynamic reconfiguration algorithm has been proposed for clustering dense RRH deployments in C-RAN.…”

Abstract-In this paper, two scenarios have been considered for millimetre wave base station configuration. In the first scenario, the approach of Distributed Base Station (DBS) with remote radio units (RRU) is chosen as the envisioned architecture for future 5G network. This approach is compatible with cloud radio access network (C-RAN), as it has easier scalability and compatibility with future network expansions and upgrades. RRU has been used in this work as a way to sidestep the limited coverage and poor channel condition, which characterise millimetre wave band. This will minimise the number of required sites installation for the same quality of service (QoS). The results of this approach have shown significant improvements in terms of User Equipment (UE) throughput, average cell throughput, and spectral efficiency. In the second scenario, optimising antenna element spacing is considered in the base station array. The results show significant improvement in the network performance and provide better performance for cell-edge users in terms of data throughput.
