Specifically, we incorporate NOMA with the decode-and-forward (DF) relay protocol, where the destinations can receive the signals of the source and the relay simultaneously via NOMA. Theoretical analysis demonstrates that the proposed NOMA-DF-relay protocol is superior to the traditional orthogonal multiple access (OMA) based DF-relay protocol in terms of data rate. To fully exploit the advantages of the proposed protocol, we formulate a joint UAV height optimization and channel allocation problem with the objective to maximize the total data rate under the constraints of the rate requirement of each user. Based on the golden section method and the matching theory, we propose an efficient algorithm to solve the formulated problem optimally. Simulation results indicate that the NOMA-DF-relay protocol is superior to the OMA-DF-relay protocol, and the proposed algorithm can further improve the total data rate in comparison with the other schemes.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127827657","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 deficiencies of cloud computing, such as centralized deployment, network congestion and the long distance from the terminal, make it hard to satisfy vehicular service demands. As a promising computing paradigm, Multi-access Edge Computing (MEC) can be applied to IoV scenarios. The resource management in the changeable MEC environment has become a challenging problem to be addressed. In particular, it should be noticed that IoV tasks have different sensitivities to delay and need to be treated differently. In this article, we focus on the Joint Task Scheduling and Resource Allocation problem in the MEC based vehicular system, proposing a JTSRA algorithm. Firstly, we classify computing tasks into different priorities according to their delay tolerances. Based on this, in order to improve processing efficiency, we design an approach to adjust the order of tasks. Moreover, we further transform the computing resource allocation problem into the Markov decision process and solve it with reinforcement learning. Finally, the feasibility and effectiveness of the proposed scheme are verified by simulation.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132659876","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 Cloud radio access networks (C-RAN) coordinate transmission among base stations (BSs) and reduce the co-channel interference to a large extend. In this work we have studied performance gains of FD in reduced interference environment of C-RAN with fixed cluster size. We derived bound for signal-to-interference-plus-noise ratio distribution and achievable rates for both uplink and downlink. We show that FD in C-RAN can improve the cell edge as well mean rate.

All these network devices require that they be properly configured and maintained, which creates a challenge for system administrators of complex networks with a growing variety of heterogeneous devices. This challenge is true for today's networks, as well as for the networking architectures of the future, such as Named Data Networking (NDN). This paper gives a preliminary design of an NDNconf framework, an adaptation of a recently developed NETCONF protocol, to realize unified configuration and management for NDN. The presented design is built leveraging the benefits provided by NDN, including the structured naming shared among network and application layers, stateful data retrieval with name-based interest forwarding, in-network caching, data-centric security model, and others. Specifically, the configuration data models, the heart of NDNconf, the elements of the models and models themselves are represented as secured NDN data, allowing fetching models, fetching configuration data that correspond to elements of the model, and issuing commands using the standard Interest-Data exchanges. On top of that, the security of models, data, and commands are realized through native data-centric NDN mechanisms, providing highly secure systems with high granularity of control.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"1998 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132291713","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}

Ubiquitous wireless communication network, especially WiFi promotes the development of relevant industrial applications as well as the academic researches. Without dedicated equipment and specific constraints, device-free human activity sensing based on WiFi has attracted widespread attention. Prevailing approaches have made great achievements in single location perception and multi-locations fusion perception. However, in practical applications how to realize location-independent sensing using as few samples as possible to achieve highaccuracy recognition is an essential and fairly crucial issue, but still a challenge. To solve the issue, we present a location independent human activity recognition system based on WiFi named WiLISensing. In this paper, we leverage a simple designed Convolutional Neural Network (CNN) architecture and transfer learning method based on it to recognize activities in a position without training or with very few training samples. What's more, we demonstrate why transfer learning is a better solution to this problem. Extensive experiments have been carried out to show that WiLISensing could achieve promising accuracy above 90% in recognizing six activities and outperform state-of-the-art approaches.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134229291","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 goal is to minimize the peak age-of-information (PAoI) by jointly optimizing the flight trajectory of the UAV, the service time of data packets, and the power allocation for packet transmission. The feasibility condition of the joint design problem is first derived. Since the joint design problem is highly non-convex, we propose an efficient iterative algorithm based on the successive convex approximation to transform this non-convex problem into convex optimization problems, which can thus be efficiently solved by the off-the-shelf solvers. The simulation results show that the proposed algorithm performs better than that based on the alternating optimization. The energy and power constraints have a significant impact on the PAoI. Meanwhile, when the energy is limited and/or the packet loads are heavy, the PAoI is dominated by the flight time of the UAV.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"175 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114003813","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}

For example, it is not clear if an ML method can accurately predict achievable KPIs (e.g. throughput) and the probability of coexistence (PoC) of LTE-LAA coexistence systems based on partial or no information of MAC and physical layer protocols and parameters. In this paper, we develop a novel ML method by combining a neural network with a logistic regression algorithm to track and estimate KPIs and PoC of coexisting LTE-LAA and wireless local area network (WLAN) links. This ML method can be applied when KPI samples at the base stations (BSs) and access points (APs) are available, without using knowledge of MAC and physical layer parameters. Comparison between the ML and simulation results indicate that the proposed ML method can track the system KPIs and predict the system PoC with good accuracy.","PeriodicalId":254869,"journal":{"name":"2020 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116707132","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}
