An effective user pairing strategy in a cluster can increase the capacity of downlink NOMA system consistently. In this paper, we propose a novel hybrid user pairing to process a case where the number of far users in a cell is larger than the number of near users. Conventional NOMA divides users into multiple groups according to their channel gains, however, there will be a large amount of far users left when the pairing of near users is completed in this scenario. In such case, we allow multiple far users being paired with one near user to optimally utilize the spectrum of far users in the NOMA system, and multiple far users share the same bandwidth. We have compared the proposed algorithm with conventional NOMA, OMA and some algorithms proposed in other papers, simulation results show that the proposed algorithm can significantly increase the system capacity. The superiority of the proposed algorithm is also analyzed from the perspective of user fairness.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123749018","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, wireless devices (WDs) can not harvest sufficient energy and the link used for offloading tasks is hostile due to the doubly attenuation. Fortunately, the efficiency of wireless power transfer and spectrum can be improved significantly by intelligent reflecting surface (IRS), which can steer the incident signal collaboratively. This paper proposes a wireless powered MEC network assisted by the IRS, where the WDs follow a binary offloading rule. Our objective is to maximize the system computation rate by jointly optimizing the downlink and uplink passive beamforming of all IRSs, computing modes of the WDs and time allocation for wireless power transfer (WPT) and task offloading. The block coordinate descent (BCD) method is introduced to decompose the original problem into three sub-problems. The major difficulty is caused by the combinatorial nature of the WDs' computing mode selection. To solve this problem, we propose a duplex coordinate descent with dictionary (DCDD) method to obtain a sub-optimal solution with high efficiency. Numerical results show that the proposed scheme can achieve significant performance gains over the benchmark schemes without IRS.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123760961","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}

Due to the panoramic and high resolution features, limited bandwidth and stringent latency requirements, the transmission of full high-definition 360-degree video may cause severe stalling, significantly lowering the users' quality of experience (QoE). As the video content seen by the user largely relies on the user's viewing direction and the size of field of view, in this paper, we investigate viewpoint prediction and dynamic tile selection to improve users' QoE for mobile 360-degree video streaming. Specifically, we first design a recurrent neural network integrated with attention mechanism to predict the user's viewpoint in the next video segment. We then propose a dynamic tile-selection method which selects and transmits the tiles that are most likely to be viewed in a segment through online learning. Experimental results based on a real-world dataset show that, the proposed viewpoint prediction neural network and dynamic tile selection method can effectively improve the prediction accuracy and improve the users' QoE.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"37 24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134506337","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}

Nevertheless, private information can still be inferred from the communicated model parameters by adversaries. In addition, due to the limited channel bandwidth, the model communication between clients and the server has become a serious bottleneck. In this paper, we consider an FL framework that utilizes local differential privacy, where the client adds artificial Gaussian noise to the local model update before aggregation. To reduce the communication overhead of the differential privacy-protected model, we propose the universal vector quantization for FL with local differential privacy mechanism, which quantizes the model parameters in a universal vector quantization approach. Furthermore, we analyze the privacy performance of the proposed approach and track the privacy loss by accounting the log moments. Experiments show that even if the quantization bit is relatively small, our method can achieve model compression without reducing the accuracy of the global model.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132544391","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}

To manage the interference among different layered users, a centralized spectrum access system (SAS) combined with a central database is utilized to coordinate the spectrum access of lower-tiered users. Therefore, the centralized management architecture of the CBRS system cannot efficiently manage very large scale and large quantity of users, and may also suffer severe security and privacy issues. To address these problems, in this paper, we propose a new blockchain-assisted dynamic spectrum management model based on existing CBRS model, where the blockchain technology is leveraged to improve the spectrum management efficiency and quality-of-service of the GAA users. Furthermore, we design a detailed flow of the spectrum management of GAA users, where a dedicated graph coloring algorithm is proposed to obtain the optimal channel assignment strategy. Simulation results have increased the ratio of GAA users licensed and improved spectrum utilization under the proposed algorithm.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125365233","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}
