The proposed antenna consists of a microstrip Rotman lens and a nine-element circular array antenna which utilizes high-gain patch element in order to enhance the gain of OAM beam. A stacked patch loaded with two slots is attached above the patch element to effectively enhance the antenna gains. By employing the Rotman lens as the feed network of the circular array, nine OAM-carrying beams and can be produced when different input ports are excited, respectively. 160°-phase-shift on adjacent output ports can be achieved to meet the phase requirement of OAM higher modes . Moreover, the Rotman lens is modified by adjusting the deflection angle of the beam ports and array ports so as to achieve uniform amplitude distribution on the output ports. Hence, the pattern characteristics of OAM beams can be effectively improved by making all the output ports equal in amplitude. The C-band prototype of the antenna is fabricated and measured. Both the simulation and measurement results indicate that nine OAM modes can be generated by using the proposed structure. The proposed antenna can be used in an OAM-based wireless communication system.","PeriodicalId":443582,"journal":{"name":"2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123575459","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 ray-tracing based and a geometry-based stochastic channel models developed in the project are then described. These models can be used to simulate systems involving terrestrial and non- terrestrial networks. We then describe three different ways investigated in the project for managing interference: signal processing (hardware implementation of a 5G New Radio compatible physical layer), beamforming (steering and switching beams in order to avoid the interference while preserving the spectral efficiency) and radio resource management (tool designed for joint optimization of satellite and terrestrial resource sharing).","PeriodicalId":443582,"journal":{"name":"2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131458233","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}

Our objective is to determine the optimal topology of vehicle connectivity which maximizes the number of admitted primary vehicles, while associating all secondary vehicles to ensure the coverage. We cast the optimization problem as an l0 minimization problem. This problem is known to be combinatorial and NP-hard. Hence, we propose a sub-optimal, two- stage algorithm to solve it.

This paper investigates the utility optimization for cache-aided ultra-dense relay networks (CUDRNs) by a preference-aware caching and stable matching scheme. First, we divide the nodes, which may act as a user or a relay, into multiple clusters, and perform optimization strategy within the clusters. Second, the file caching scheme is designed by taking user preference and file popularity into account. Third, according to the performances of the file caching scheme, the optimal power bought from the relay to maximize the utility of the user is derived by an iterative algorithm, and the mutual preference matrices between the users and relays by the maximum utility criterion is established. Then, we propose a user-relay stable matching (SM) strategy by exploring the Gale- Shapley (GS) algorithm. Simulation results demonstrate that the proposed algorithm can bring significant performance improvements compared with the conventional algorithms.","PeriodicalId":443582,"journal":{"name":"2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117002825","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}
