  • Heterogeneous Networks Evolution and Operations - System Requirements and Architecture

    The purpose of this document is, based on the companion deliverable on Wi-Fi use cases, to derive system level requirements for cellular operator integration of Wi-Fi access networks. The system level requirements are mapped onto on-going standardization activities with the objective to identify any gaps, and conclude with recommendations on standardization and industry activities.

  • Heterogeneous Networks Evolution and Operations - Use Cases

    Increasing complexity and heterogeneity of mobile networks may result in increasing operations divergence. This leads to a low level of end-to-end control of the system (policy enforcement) which finally results in low user experience (reselection, mobility, battery lifetime, automatic customer premises equipment configuration). The result of the project on Heterogeneous Networks Evolution and Operations is the definition of use cases and related requirements for fast and appropriate operation of heterogeneous networks. This deliverable is defining the use cases and high level requirements for WiFi interworking and interoperation with LTE networks.

  • NGMN Recommendation on Base Station Antenna Standards

    This white paper addresses the performance criteria of base station antennas (BSAs), by making recommendations on standards for electrical and mechanical parameters, and by providing guidance on measurement practices in performance validation and production. It also addresses recommendations on applying existing environmental and reliability standards to BSAs.

  • Multi-Antenna Technology - Multi-Antenna Future Requirements

    This deliverable is produced by the NGMN project MATE –Multi-Antenna technology. It provides the guideline for future multi-antenna development and deployment. The document concludes 4 main technical trends and requirements of multi-antennas and then introduces the solutions and key parameters as reference. Lastly, potential future antenna types are discussed.The intention is to provide a specific, yet generic, description of future multi-antenna requirements.

  • NGMN Project Report: Multiband Multimode Requirements - Multiband Multimode Technology Evolution and Global Roaming

    This deliverable is the final deliverable of the project P-MBMM. The project investigated the possibilities to reach a common UE product implementation platform that supports all global operators’ near term LTE deployment scenarios including both FDD and TDD, and plus necessary legacy network support for needed fall-back mechanisms. The goal of the project was to create a better understanding of the practical possibilities and technology feasibility roadmap, while creating realistic expectations, driving requirements and alignment, and communicating a common message to the ecosystem.

  • C-RAN Liaisons, Contributions to 3GPP ETSI on Collaborative Radio/MIMO, ORI Interface

    This document identifies the potential impact in standards from multi-vendor CRAN implementations. The starting point of this analysis is a set of requirements expressed in another subtask of the CRAN project, along with the definition of the CRAN building blocks. Some of these requirements mandate the possibility to build CRANs from building blocks designed by different vendors. These requirements impose open interfaces and interoperability between the relevant CRAN building blocks. Another set of requirements is purely design and implementation related, which is out of scope for this document. Standards bodies such as 3GPP, being enablers of multi-vendor interoperability, have defined open interfaces between the functional elements of the UTRA and E-UTRA radio access networks as well as the core network. These interfaces were not originally designed to support CRAN, but fortunately most of them can support many physical implementations of the functional CRAN architecture. It is the objective of this document to establish if such functional interfaces are suitable for CRAN, and identify possible gaps that will preclude interoperability.

  • Suggestions on Potential Solutions to C-RAN

    This document of „Suggestions on Potential Solutions to C-RAN“ studies key technologies critical for C-RAN realization. Starting from scenarios suitable for C-RAN deployment, major functionalities of C-RAN are presented, some of which distinguish C-RAN from traditional systems. To fullfill the critical functions and to exploit the potentials of C-RAN such as resource sharing, possible solutions are studied and suggested. The document ends with suggestion on how traditional RAN could evolve to C-RAN step by step and the trend on fiber transport networks.

  • Backhaul Evolution - Integrated QoS Management

    This document aims to develop a framework for "Integrated Quality of Service Management" for mobile backhaul as part of the wider "Backhaul Evolution" project. This stream is focused mainly on service flow classification and inter-layer Class of Service alignment, continuing previous work started in NGMN project OSB (Optimized Solutions for mobile Backhaul). A further topic for analysis is the use of integrated QoS management mechanisms involving both radio and transport nodes, but this is out of scope of the current document, as will be detailed below.

  • Multi Antenna Technology Antenna Co-Site Solutions

    This document provides the solutions of co-site antenna to reduce the antenna installation space and requirement for 2G/3G/4G.
    This deliverable from project P-MATE focuses on the solutions for 2 path and 8 path co-site antenna. It includes two main solutions: 2 path antenna solutions which are based on the requirements of FDD/TDD/3G/GSM co-site; 8 path antenna solutions which are based on the requirements of FDD-TDD,TDD-TDD LTE and TDD LTE-3G co-site.

  • Multi-Antenna Technology Compact Antenna Solutions

    This document provides the solutions of compact antenna to reduce the difficulty of antenna deployment for information sharing. This deliverable focuses on the conclusion and summary of some basic modes from operators and vendors experiences. This document includes basic mode and compact mode with 2 interface innovation extensions. BMA and MCIC are two interface extensions for improving the performance of interface between antenna and RRU (Remote Radio Unit). The compact solution is the combination of basic mode and interface improvement in urban/dense urban. The intention is to provide a specific, yet generic, description of basic modes for compact antenna features.
