In this paper, we present an analytical framework to evaluate the coverage in the uplink of millimeter wave (mmWave) cellular networks. By using a distance dependent line-of-sight (LOS) probability function, the location of LOS and non-LOS user equipment (UE) are modeled as two independent non-homogeneous Poisson point processes, with each having different pathloss exponent. The analysis takes account of per UE fractional power control (FPC), which couples the transmission of UE due to location-dependent channel inversion. We consider the following scenarios in our analysis: 1) Pathloss based FPC (PL-FPC) which is performed using the measured pathloss and 2) Distance based FPC (D-FPC) which is performed using the measured distance. Results suggest that D-FPC outperforms the PL-FPC at high SINR. Also, the SINR coverage probability decreases as the cell density becomes greater than a threshold.

The next generation of mobile networks, 5G, is currently under development by the industry, academia and international standard organizations. The key drivers of 5G are to provide incomparable more capacity (1000×), extremely lower latency (sub-millisecond) and to accommodate ‘any’ type of user (e.g. machines) in the network. Software-defined networking (SDN) and network function virtualization (NFV) technologies promise to bring an unprecedented level of flexibility in resource management. This paper presents a radio frequency spectrum management framework that is suitable to programmable 5G networks, under the overarching architecture of the 5G PPP COHERENT project. It also provides description of the recent advances and up-to-date initiatives for resource management in programmable 5G networks. The core contribution consists in the design of an SDN-enabled spectrum management application (SMA), and the related abstraction models that have been developed to enable flexible spectrum management. This paper demonstrates that suitable policy and topology abstraction models are key to spectrum management and sharing process.

This paper presents simulation results of a dual-polarized 2×2 element sub-array antenna element at 15 GHz center frequency. The basic idea is to use two waveguides stacked on in a right-angle configuration to excite the orthogonal polarizations by using radiating slots. Above the slots, 4 parasitic patches are set to a form of 2×2 element sub-array. Antenna presents −10 dB impedance bandwidth from 14.3 to 15.6 GHz with better than 68 dB isolation between the excitation ports. At the aforementioned bandwidth, the total efficiency is better than −0.7 dB (> 85%). Antenna shows very good polarization properties and difference between ϕ, θ components is greater than 45 dB. Also the radiation patterns and surface current distributions at 15 GHz center frequency are presented and compared.

We consider the resource allocation with aggregation of multiple bands including unlicensed band for heterogeneous traffic. While the mobile data traffic including high volume of video traffic is expected to increase significantly, an efficient management of radio resources from multiple bands is required to guarantee the quality of service (QoS) of different traffic types. In this context, we formulate an optimal resource allocation by using different utility functions for heterogeneous traffic and the two-step resource allocation algorithm including resource grouping has been proposed. Simulation results demonstrate that the proposed algorithm enhances the connection robustness and shows good performance in terms of higher utility value of inelastic traffic even at high traffic loads by steering elastic traffic to unlicensed band.

Cloud federation is receiving increasing attention due to the benefits of resilience and locality it brings to cloud providers and users. Our analysis of three diverse use cases shows that existing solutions are not addressing the federation needs of such use case applications. In this paper, we present an alternative approach to network federation, providing a model based on cloud-to-cloud agreements. In our scenarios, companies hosting their own OpenStack clouds need to run machines transparently in another cloud, provided by a company they have an agreement with. Our solution provides multiple benefits to cloud providers and users detailed in this paper. Our implementation outperforms the VPNaaS solution in OpenStack in terms of throughput.

Nonlinear power amplifiers distort the transmitted signal and out-of-band (OOB) radiation becomes a source of interference for users operating in adjacent channels. This paper studies the effect of Massive Multiple Input Multiple Output (MIMO) system on the OOB interference. Massive MIMO relies on channel based precoding which ensures the signal is added constructively at the receiver user equipment. However, the effect of the precoding on the OOB radiation should be investigated given that a random user could experience an increased interference. Assuming a third order polynomial model to describe the behavior of the power amplifier, we model the received power spectrum density. Mathematical analysis and system level simulation confirm that OOB does not recombine constructively avoiding large interference. Massive MIMO allows to increase the in-band received power for the target users without increasing the interference in adjacent bands. In other words, less stringent requirements are demanded for power amplifier design, confirming that simpler hardware with respect to conventional transmission scheme is sufficient. We show that in Massive MIMO, even power amplifiers with efficiency of 65.4% satisfy 3GPP OOB constraints.

In this paper, candidate coding schemes are investigated for the new radio access technology (RAT) of the fifth generation (5G) mobile communication standard. Enhanced mobile broadband(eMBB) scenario of the 5G standard corresponding the activities in the third generation partnership project (3GPP) is considered. The coding schemes are evaluated in terms of block error rate (BLER), bit error rate (BER), computational complexity, and flexibility. These parameters comprise a suitable set to assess the performance of different services and applications. Turbo, low density parity check (LDPC), and polar codes are considered as the candidate schemes. These are investigated in terms of obtaining suitable rates, block lengths by proper design for a fair comparison. The simulations have been carried out in order to obtain BLER / BER performance for various code rates and block lengths, in additive white Gaussian noise (AWGN) channel. It can be seen from the simulations that although polar codes perform well at short block lengths, LDPC has a relatively good performance at all the block lengths and code rates. In addition, complexity of the LDPC codes is relatively low.

This paper investigates a signal area (SA) estimation method for spectrum measurements. The spectrum measurements is for estimating statistical information of spectrum usage and required latency is not very critical compared to spectrum sensing. SA denotes the area (in time/frequency domain) occupied by the primary user's signal. The traditional approach, which utilizes Fourier transform (FT) and energy detector (ED) for SA estimation, can achieve low complexity, but its estimation performance is not very high. For this issue, we propose a post-processing, simple SA (S-SA) estimation. S-SA estimation exploits the correlation of the spectrum states among the neighboring tiles, i.e., time/frequency grids, and the fact that SA typically has a rectangular shape to estimate SA with high accuracy and relatively low complexity compared to a conventional method, contour tracing based SA (CT-SA) estimation. Numerical results will show that the S-SA estimation method can achieve better detection performance than CT-SA. Furthermore, it can reduce the computation time compared to the CT-SA estimation.

To address demanding requirements in terms of expected throughput, latency and scalability, 5G networks will offer high capacity to support huge volumes of traffic generated by heterogeneous services. Dense deployment of small cells can provide a valid solution but are prone to high levels of interference especially at the cell-edge. However, to reduce inter-cell interference and improve cell-edge throughput, a set of techniques known as Coordinated Multipoint (CoMP) has been introduced. Coordinated Scheduling (CS) is a CoMP technique that assigns resources to mobile users to avoid interference between users that are assigned within the same Physical Resource Blocks (PRBs). On the other hand, Software Defined Mobile Networking (SDMN) and Network Function Virtualization (NFV) represent two key technologies to enhance flexibility and efficiency of resource usage within the Radio Access Network (RAN). However, the implementation of CoMP CS techniques on NFV architecture in a dense small cell scenario have not been analyzed yet. In this paper, we propose the joint use of CoMP CS and NFV by studying the implications of different deployment strategies, as constrained by the physical topology of the underlying RAN. The performance of both distributed and centralized CoMP CS are compared in terms of convergence delay and traffic overhead. Guidelines for the optimal design are provided.
