Billions of interconnected devices that are connected to the internet in the IoT (Internet of Things) will produce astronomical amount of data to process. The amount of data can easily overload the cloud computing resources at the back-end IT systems. With Fog (or Edge) computing, the problem can be eased by allowing smart devices (e.g., smartphones, PCs, set-top boxes) at the edge of the IoT networks.

Ultra-Reliable Networks – A Mobile Operator Perspective

In this update of his past presentations on Mobile Eating the World -- delivered most recently at The Guardian's Changing Media Summit -- a16z’s Benedict Evans takes us through how technology is universal through mobile. How mobile is not a subset of the internet anymore. And how mobile (and accompanying trends of cloud and AI) is also driving new productivity tools. In fact, mobile -- which encompasses everything from drones to cars -- is everything.

Still NR Rel.15 was primarily designed for high frequency, high throughput small and mid-range communication systems mostly in dense urban and urban macro environments. In our view, this leaves out a large number of poorly connected populations that live in rural areas without viable solution even for basic broadband communication. We want to address this issue in the NR Rel.17 RAN1 work item on coverage enhancement. Discussion will start tonight in the 3GPP RAN1 e-meeting. This document discussed open issues regarding coverage in long-distance scenarios. In addition, this document illustrates the baseline coverage performance of extreme long–range rural scenarios for FR1 700 MHz both in DL and UL based on system-level simulations.

5G NR Coverage Analysis for 700 MHz

Nomor Research contributed extensive system level simulation results to the evaluation group of the 5G-PPP consortium as an independent source. The evaluation has been submitted to 34th meeting of the ITU-R Working Party 5D confirming that the 5G requirements of 3GPP New Radio air interface are indeed fulfilled. With the presentation of the evaluation reports at the ITU-R Working Party 5D meeting held in Geneva, Switzerland, in February 2020, the independent evaluation activity has officially been closed. The system level simulations performed by Nomor Research GmbH are only a part of the overall evaluation of the 5G NR air interface. A summary of the simulation-based evaluation based on the 5G NR RealNeS system simulator is being provided in this white paper.

Final Performance Evaluation of 3GPP NR eMBB within 5G-PPP consortium

In this paper we would like to emphasize once again the need to look at large coverage scenarios for 5G NR and express our support for the creation of a Rel.17 work item. Furthermore, we provide first system-level simulation results to further motivate work on coverage enhancements and prove our commitment to contribute to a study item in the working groups in Rel.17 with independent performance evaluation.

Motivation and results coverage enhancment for 3GPP NR Rel.17

3GPP RAN plenary meeting #84 in Newport Beach, US, in June 2019, discussed the content of 5G New Radio (5G-NR) Release 17 standardization. One of the defined key areas for 5G enhancements for 5G enhancements is NR Broadcast / Multicast (BC/MC). Important use cases for this technology are NR Vehicle-to-Everything (V2X), NR Public Safety and NR Non-Terrestrial Networks (NTN). This white paper proposes a mechanism of link adaptation in coordination with higher layer Error Correction. A detailed description and system-level simulation-based evaluation of the proposed scheme is provided in this White Paper.

Status of 3GPP NR Rel.16 NR bands and band combinations

In this paper, we define a flexible, adaptable, and programmable architecture for 5Gmobile networks, taking into consideration the requirements, KPIs, and the current gaps in the literature, based on three design fundamentals: (i) split of user and control plane, (ii) service-based architecturewithin the core network (in line with recent industry and standard consensus), and (iii) fully flexible support of E2E slicing via per-domain and cross-domain optimisation, devising inter-slice control and management functions, and refining the behavioural models via experiment-driven optimisation.The proposed architecture model further facilitates the realisation of slices providing specific functionality, such as network resilience, security functions, and network elasticity. The proposed architecture consists of four different layers identified as network layer, controller layer, management and orchestration layer, and service layer. A key contribution of this paper is the definition of the role of each layer, the relationship between layers, and the identification of the required internal modules within each of the layers. In particular, the proposed architecture extends the reference architectures proposed in the Standards Developing Organisations like 3GPP and ETSI, by building on these while addressing several gaps identified within the corresponding baseline models. We additionally present findings, the design guidelines, and evaluation studies on a selected set of key concepts identified to enable flexible cloudification of the protocol stack, adaptive network slicing, and inter-slice control and management.

Status 3GPP LTE-V2X work item on vehicular communication - Sept 2016

The System and Service Aspects – Architecture group (SA2) of 3GPP has a dedicated study item for the study of the next generation networks. It is expected that this work will form the basis of the system architecture for the future 5G networks. Within SA2 group, regular meetings and discussions are held to discuss the progress of this study item. NoMoR Research follows these activities. This report presents a condensed summary of the earlier mentioned study item, including the latest updates from the most recent meeting held in Vienna, Austria from 11th – 14th July, 2016.

3GPP Newsletter: Status 5G Architecture Study in 3GPP SA2

LTE, which was originally designed with fixed FDD or TDD modes with little flexibility for varying the capacity split between uplink and downlink, is being augmented with features that allow for more flexible use of radio resources. One of these features is “enhanced Interference Mitigation and Traffic Adaptation” (eIMTA) which notably allows for very dynamic adaptation of the TDD pattern e.g. in response to varying capacity requirements in uplink and downlink. eIMTA was standardized in LTE-A Release 12 and eIMTA-like functionality is considered to be one of the key enablers for 5G technologies. The purpose of this paper therefore is to shed some light on eIMTA, its main characteristics and capabilities and to illustrate its behaviour by means of system-level simulations.

White Paper: Dynamic TDD for LTE-a (eIMTA) and 5G

LTE networks get more mature and new terminals of different capabilities are being introduced. 3GPP just defined the new LTE-A UE categories to support terminals with peak data rates of up to 450 Mbps in the downlink. This white paper provides an overview of all existing LTE/LTE-A UE categories and presents the new Release 11 capabilities that have just been standardized. Furthermore it describes key scenarios and use cases such as the support for downlink carrier aggregation with 3 downlink carriers with up to 60 MHz of total bandwidth.

Future LTE-A UE Capabilities - 450 Mbps and Beyond

Initial deployments of LTE networks are based on so-called homogeneous networks consisting of base stations providing basic coverage, called macro base stations. The concept of heterogeneous networks has recently attracted considerable attention to optimize performance particularly for unequal user or traffic distribution. Here, the layer of planned high-power macro eNBs is overlaid with layers of lower-power pico or femto eNBs that are deployed in a less well planed or even entirely uncoordinated manner. Such deployments can achieve significantly improved overall capacity and cell-edge performance and are often seen as the second phase in LTE network deployment. This paper discusses the concept of heterogeneous networks as compared to homogeneous networks. It demonstrates the need for inter-cell interference coordination (ICIC) and outlines some ICIC methods that are feasible with release 8 /9 of the LTE standard. System-level simulation results illustrate the benefits of the various features discussed in the following.

Heterogeneous LTE Networks and Inter-Cell Interference Coordination - Dec 201...

Multi-layer heterogeneous network layout including small cell base stations are considered to be the key to further enhancements of the spectral efficiency achieved in mobile communication networks. It has been recognized that inter-cell interference has become the limiting factor when trying to achieve not only high average user satisfaction, but a high degree of satisfaction for as many users as possible. Therefore, inter-cell interference coordination (ICIC) lies in the focus of researchers defining next generation mobile communication standards, such as LTE-A. Building upon [1], this paper provides an overview over the background calling for ICIC in heterogeneous LTE-A networks. It outlines techniques standardized in Rel. 10 of LTE-A, discusses them showing their benefits and limitations by means of system-level simulations and motivates the importance of self optimizing network (SON) procedures for ICIC in LTE-A.

Some of the key driving forces behind the transition from the UMTS based cellular system to the Long Term Evolution Advanced (LTE-A) are to improve the mean and the cell-edge throughput, improve the user fairness, and improve the quality of service (QoS) satisfaction for all users. In the latter system, relays appear as one of the most prominent enabler for improving the cell-edge user experience while increasing the system’s fairness. In this white paper, we present the basics of relay deployments in LTE-A networks. Moreover, we analyze resource allocation problem for Relay Nodes (RN) deployments and present some of the solutions for improvement in system resource usage and QoS satisfaction. Afterwards, we introduce the capabilities of NOMOR’s LTE-A system level simulator and evaluate the performance of LTE-A relay systems under the described solutions.
