To support such applications in 5G, not only the conventional area traffic capacity but network energy efficiency is also a critical factor since energy consumption of information processing is also becoming an economic issue for operators. Dealing with this problem, our project considers a C-RAN based cloud cooperated HetNet architecture which enables global resource optimization among smallcells to maximize objective functions of interest e.g. energy efficiency. On the other hand, a dynamic traffic model based on that the network can dynamically adapt to the variation in a cost-effective way is also crucial for the design of 5G. This paper develops such traffic model based on realistic measurement data in metropolitan Tokyo. Based on the developed model, a on-demand cell activation / deactivation jointly with user association mechanism is applied to maximize the network's energy efficiency defined as the system rate over the total consumed energy. Numerical results show the effectiveness of the proposed algorithm against dynamic variation of hourly traffic while improving users' satisfaction as compared to conventional homogeneous network. The paper also confirms the superiority of mm-wave smallcell HetNet against conventional microwave HetNet in terms of energy efficiency in bps/W.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126026699","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}

This opportunity requires a new mindset among these actors that corresponds to re-positioning in the Smart City value chain. This means that, in order to play a role that can not be overlooked, Telecom actors should perform rather different blocks of the Smart City value chain compared to their traditional activity blocks in Mobile Telephony value chain. The Fifth Generation of mobile telecommunications technology (5G), by some actors, is then considered as the major ICT enabler for this new paradigm. This paper intends to highlight the role of Machine Type Communications (MTC) for enabling Smart Cities. In order to do so, we introduce the building blocks of Smart City followed by four use cases from Intelligent Transport Systems and Digital Built Environment. We use these cases as the proof of concept for defining the generic MTC activities in the context of Smart City. Eventually the paper introduces the MTC value network in the context of Smart City, based on the resources associated with the activities.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128684606","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 the horizon 2020, the key improvements will rely on technical breakthroughs in the radio access networks, mainly to bring increased bandwidth to the user devices. However, there is still much discussion ongoing about the evolution required in the core network to accommodate increased demands from existing services (e.g. in the number of devices) and services which are not feasible or efficiently implemented with today's architecture. Disruptive approaches can even be considered if the horizon for such changes is extended to 2025. Due to the advance of virtualization and SDN technologies, it is very promising that the current mobile core network could gain more flexibility, support multiple radio access network generations in parallel, and meanwhile enrich its ecosystem to generate new revenue opportunities. In this paper, we would like to discuss the feasibility to design a flexible and adaptive mobile core network based on functional decomposition and network slicing concepts. This paper will provide a guideline and enlighten strategic directions for future mobile core network research.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131443163","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 problem of maximizing energy efficiency (EE) of data transmissions in the system is studied by optimizing the number of antennas per BS, the pilot signal power, and the data signal power. The considered optimization problem takes into account the circuit power consumption, pilot contamination, and budget constraints in the number of antennas per Base Station (BS) and the average transmission power per symbol. The resulting optimization problem has a non-convex fractional objective function which is difficult to solve in its original form. Therefore, principles from fractional programming are used to first transform the problem into an equivalent parametric form and then to derive an iterative resource allocation algorithm. In each iteration, an alternating optimization technique is used to solve the objective function by decomposing it into a sequence of solvable difference of convex (D.C) programming subproblems. Simulation results show that higher EE levels can be achieved by optimizing the pilot and data powers separately. Also, increasing the number of antennas per BS with the power budget may or may not be energy-efficient, depending on the range of operation.","PeriodicalId":436094,"journal":{"name":"2016 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123249046","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}
