In this regard, a twofold split of the processing in the radio access network is under discussion: A control plane / user plane split to support the software defined networking principle and a radio protocol stack layer based split to allow a flexible placement of processing functions between a central and distributed units. In this work, the motivation and state of the art for both splits are described including a discussion of the advantages and disadvantages. It is followed by a description of a network architecture allowing a flexible implementation of these splits. This especially focuses on the required interfaces between control and user plane.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"50 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":"88509461","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}

Based on this, the increasing capabilities of satellite systems have created the consensus that such systems can satisfy the required necessities for several scenarios, such as for rural or low-density populated areas. Used in combination with a terrestrial wireless backhaul, satellite backhauls are envisaged as a solution to improve the network efficiency in terms of delivered traffic to access nodes while increasing its resiliency for the mentioned scenarios. This paper presents i) our ns-3 framework for modeling hybrid terrestrial-satellite mesh backhaul networks that carry LTE traffic and ii) a comparison of our different backpressure-based approaches against generic shortest-path routing in a low-density suburban scenario for LTE networks. Simulation results reveal the advantages of backpressure-based approaches to make an efficient use of the network resources while integrating seamlessly both terrestrial and satellite backhaul resources.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"85 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":"91009203","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}

In this paper we propose a framework where application service requirements drive a dynamic multi-layer (IP/MPLS and optical) resource allocation and optimization. We compare by means of simulations such application-aware algorithmic framework with a multi-layer but application-unaware strategy. Results show that the application-aware approach, unlike the application-unaware one, is always able to guarantee the specified service requirements to those applications whose generated traffic is accepted by the network. In addition, the application-aware strategy does not consume more network resources than the application-unaware one, but only requires a network that is more dynamic and responsive.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"14 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":"88975094","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}

It has been predicted that URLLC will play an essential role in enabling wireless communications for emerging new services and applications such as factory automation, remote manipulation, autonomous driving and tactile Internet, to name a few. The two key performance metrics related to URLLC are latency and reliability. In this paper three coordinated multi-cell resource allocation methods for 5G URLLC are presented in a typical indoor environment. From the simulation results, it can be observed that handling inter-cell interference effectively can lead to a significant performance improvement in terms of reliability without bringing any degradation to the latency performance.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"32 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":"74410724","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}

The diversity and number of these technologies is increasing constantly leading to potential interference problems and performance degradation of wireless medical applications which are expected to become popular in 5G systems. The industrial, scientific and medical (ISM) bands in the 2.4 GHz are already very crowded to the point that the location and use of medical devices have to take into account the pervasive presence of other wireless devices operating in that region of the spectrum. A temporary solution is to use more the 5 GHz bands currently not so heavily utilized. This scenario will change in the near future as unlicensed long-term evolution (LTE) solutions such as MulteFire start operating in those bands.

Cloud-enabled radio systems have been introduced as a promising solution to meet these demands with the help of network functions virtualization techniques and network edge processing capabilities, which allow for increased resource pooling, scalability, layer interworking and spectral efficiency. Despite their potential benefits, joint radio-cloud systems pose technical challenges on the network management and orchestration, especially on ensuring the Quality of Service (QoS). To this end, having a complete loop of monitoring, decision-making and reaction is essential. However, considering the fact that the radio and the cloud parameters are inherently disparate, forming such a loop in a joint radio-cloud environment is very challenging. This challenge becomes more difficult in multi-tenant (operator) scenarios, targeted by 5G, where ensuring the QoS for one tenant should not violate the QoS of the others.

This paper discusses the recently proposed energy-efficient transmit beamforming designs for multicell multiuser multiple-input single-output (MISO) systems, including maximizing overall network EE, sum weighted EE and fairness EE. Generally, the EE optimization problems are NP-hard nonconvex programs for which finding the globally optimal solutions is challenging. For low-complexity suboptimal approaches, there is a class of solutions conventionally developed based on parametric transformations. However, those have been revealed problematic in terms of computational complexity and convergence. To overcome these issues, novel algorithms have been recently developed based on the state-of-the-art successive convex approximation (SCA) framework. Here we sum up the basic concepts of the algorithms and provide numerical results which illustrate the solution quality compared to the existing methods.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"50 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84580849","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}
