When high number of devices attempt to access the system in a random access procedure, a collision happens and the transmitted data will be lost. As the base-station is not aware of how many users are colliding, it will not be able to resolve the collision. In this paper, we propose a method that enables the base-station to detect the number of colliding users in random access schemes. The proposed method capitalizes on the unique feature of frequency quadrature amplitude modulation (FQAM) that the number of active subcarriers in a FQAM symbol depends on the number of users transmitting on that symbol. Thus, in the proposed method, FQAM will be used by the users for the random access, and the base-station will estimate the number of colliding users based on the number of active subcarriers. We provide in details the channel structure, procedures and theoretical derivation of the average number of active subcarriers. Numerical simulations show that by using the proposed method the number of colliding users can be accurately detected at the base-station. Furthermore, it is shown that, with the knowledge of the number of colliding users, the base-station can successfully retrieve the users' data, and the performance of the random access schemes can be significantly enhanced.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"10 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":"85746912","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}

Some key innovative design concepts have been recently consolidating and are going to characterise the notable discontinuity between 4G and 5G systems. Among those, Architecture Modularisation, discussed in this paper, is regarded by the authors as the essential design principle to build a flexible network architecture natively supporting Network Slicing. According to this concept, conventional monolithic network functions, often corresponding to physical network elements in the existing systems, are to be split into basic building blocks defined with the proper granularity, allowing the definition of different logical architectures, tailored to 5G use cases. In this paper, a modularisation methodology is presented as a criterion to define the ‘right’ set of basic building blocks. Defined through this proposed methodology, the set of basic building blocks and the relating interfacing models are discussed. The paper concludes by proposing a candidate modular 5G network architecture, and comparing it with alternatives currently discussed within 3GPP standard working groups.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"47 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79504865","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}

A single virtual network operator providing four different classes of services negotiates the required capacity to serve its subscribers, from a centralised entity called Virtual Radio Resource Management (VRRM). The main goals of VRRM are to maximise the utilisation of resources, while maintaining a level of fairness in the allocation of data rate among different services. However, under extreme situations, the algorithm is modified to react differently, according to the offered traffic load. In general, it keeps serving a number of users having the stringiest Quality of Service (QoS), with the minimum guaranteed data rate, while the rest of users performing lowest QoS priority services are increasingly delayed. The performance of the proposed algorithm is evaluated through a practical heterogeneous network scenario and different evaluation metrics. Results show that when there is enough capacity, the algorithm is capable of satisfying the predefined service level agreements, while keeping fairness, whereas under extreme situations, it delays just enough number of users to free capacity for high priority services. In both cases, the algorithm is capable of maximising the utilisation of resources.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"11 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":"88734873","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 C-RAN the fronthaul links between processing Base Band Units (BBUs) and Remote Antenna Units (RAUs) are conventionally based on fiber optic, although its deployment cost can be excessive. Radio over Copper (RoC) is an alternative/complementary technology for the fronthauling especially suitable for self-powered indoor deployment since it leverages on the pre-existing LAN cables. In this paper we consider a RoC C-RAN architecture as a low-cost bandwidth-efficient in-building solution to guarantee enhanced indoor coverage as required by 5G and beyond mobile systems. In particular, the focus of the paper is to gain insights into the optimal resource allocation to/from the RAU equipped with multiple antennas or multiple radios (e.g., 5G and WiFi) and the cable resources to fully exploit the capabilities of the twisted-pair cable over the last 50–100m. Numerical results validate the proposed method considering a realistic radio environment where the performance of indoor users are impaired by the interference of outdoor non-cooperating cells.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"3 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":"79569288","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}

Such transport networks will consist of heterogeneous technologies that need end-to-end orchestration. In this paper, we evaluate a hierarchical resource management framework for multi-domain wireless/optical networks. More specifically, we deploy a hierarchical 5G-Crosshaul Control Infrastructure (XCI) where child controllers deal with the specificities of each technology whilst the parent controller is in charge of offering to a resource management application (RMA) the appropriate abstraction level and an end-to-end view. To understand the end-to-end behavior related with service setup, we evaluate each network segment (wireless and optical), each plane (application and control planes), and each layer of the hierarchy inside the XCI. In particular, we evaluate the aggregated path setup time (in the order of seconds) as well as each component (wireless domain contributes with tens of ms and multi-layer optical network with hundreds of ms per layer for a total in the order of seconds). Path restoration results reveal the importance of leveraging control of child controllers when requiring fast response to unexpected data plane events, since an important part of the setup delay observed is due to the RMA-parent-child controller interaction and sequential message handling.","PeriodicalId":6626,"journal":{"name":"2017 European Conference on Networks and Communications (EuCNC)","volume":"20 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":"74995558","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}
