This issue can be addressed through the adoption of the eDSA (extended Dynamic Spectrum Access) paradigm, which consists of enhanced resource management techniques with three degrees of freedom: densification, rationalized traffic allocation over heterogeneous wireless technologies, and better load balancing across the available spectrum. The objective of this paper, triggered by the ongoing work in the SPEED-5G research project, is twofold: i) present a survey of the most promising enhanced techniques for 5G networks at MAC and RRM level, and ii) propose inter-RAT mechanisms to cope with the above mentioned issues, mainly focusing on access aspects of the next-generation networks in below and above 6GHz bands.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"2 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81757186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the 5G service provisioning paradigm will also require a unified infrastructure service market that integrates multiple operators and technologies. The 5G Exchange (5GEx) project, building heavily on the Software-Defined Network (SDN) and the Network Function Virtualization (NFV) functionalities, tries to overcome this market and technology fragmentation by designing, implementing, and testing a multi-domain orchestrator (MdO) prototype for fast and automated Network Service (NS) provisioning over multiple-technologies and spanning across multiple operators. This paper presents a first implementation of the 5GEx MdO prototype obtained by extending existing open source software tools at the disposal of the 5GEx partners. The main functions of the 5GEx MdO prototype are showcased by demonstrating how it is possible to create and deploy NSs in the context of a Slice as a Service (SlaaS) use-case, based on a multi-operator scenario. The 5GEx MdO prototype performance is experimentally evaluated running validation tests within the 5GEx sandbox. The overall time required for the NS deployment has been evaluated considering NSs deployed across two operators.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"17 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86304656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, air interface protocols for 5G radio access network will be standardized in coming years by 3GPP. All basic physical layer functions for the new radio system are currently under active development in 3GPP. Due to its crucial function in scheduled system, physical layer control channel is a core element to enable all physical layer data transmission. In particular, search space allocation and transmission schemes are fundamental problems of control channel design. Both aspects have ultimate impacts on achievable control channel coverage, capacity and spectrum efficiency. As such, search space design and promising transmission schemes for control channels are thoroughly studied in this paper. Both distributed and localized search spaces are proposed to accommodate different means of control channel transmission depending on availability of channel state information at the base station. Furthermore, two types of transmit diversity schemes with different diversity orders are developed and compared by Monte-Carlo simulations. It is demonstrated from simulation results that SFBC based transmit diversity outperforms per-RE precoder cycling scheme. Moreover, high order transmit diversity schemes are also proposed and simulation results thereof exhibit clear performance benefits.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"15 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79822400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ensuring high availability and fault tolerance of VNFs is cardinal to meet the performance and service level agreement requirements. Also, with the increasing electricity demands in the Information and Communications Technology (ICT) sector, especially for the data centers, the inclination towards employing renewable (green) resources to power up the data centers is also increasing. Mitigating the carbon footprint and curbing the energy costs have been the driving factors for push towards employing the green energy resources. However, the Green energy supply is rather intermittent and unstable. In this work, we study the impact of deploying VNFs in Green Data Centers (GDCs) and make a case for addressing the VNF reliability and high availability to effectively tackle the stability concerns of GDC. To this extent, we present REARM, which adopts the concept of Transient VNFs that rely on a very short advance warning time to seamlessly migrate the VNFs from GDC to a more reliable and stable Data Centers (SDCs). Our experiments with container based VNFs demonstrate that adaptive state transfer mechanism results into significant reduction in both computation and communication overheads for maintaining the NF replica, and warning time of 30ms is sufficient to failover VNFs (serving 1K flows) within a data center to ensure high availability of NFV services.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76840216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
