Integrating UAVs into cellular networks is regarded as a promising approach to meet such goals. However, given the unique UAV-ground channel characteristics and the fact that the existing cellular network has been mainly designed to serve ground users, it is not immediately clear whether the new aerial users can be supported in a similar manner as the ground users. In this paper, we provide the performance analysis for cellular-connected UAVs based on stochastic geometry, by studying the association probability and signal-to-interference-and-noise ratio (SINR) with two different association policies, namely nearest-distance based and maximum-power based associations. One striking difference of our work as compared to most existing analytical works is the use of the practical three dimensional (3D) antenna model at the base stations specified by 3GPP, which is important for more accurate performance analysis with UAV users of much higher altitude. Some useful observations are obtained based on our theoretical analysis and numerical results.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129702946","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}

Based on this novel closed-form result, this paper proposes a total spectral efficiency maximization algorithm, subjecting to each user's quality-of-service (QoS) constraint, transmission power constraint, and successive interference cancellation (SIC) constraint. The original problem is non-convex, and hence, the sequential convex approximation (SCA) method is utilized in this paper and converts this issue into an iterative geometric programming (GP) problem. Simulation results demonstrate that CF-mMIMO-NOMA is able to exploit the scarce spectrum bands more efficiently than the orthogonal multiple access (OMA) counterpart. Furthermore, the proposed algorithm has a faster convergence rate and is able to significantly improve the total spectral efficiency, compared with the equal power control (EPC) scheme.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128734648","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 last decade, there has been a significant upsurge of research in the field of integrated THz technology that has focused on enabling efficient and compact Terahertz systems operable at room temperature and deployable at large scales. In this, silicon-based integrated circuit technology can potentially provide a scalable platform. The benefits span from its level of integration right from the THz front-end to the back-end digital signal processing to high yield and low cost exploiting economies of scale. The impact of such silicon-based systems in the sister millimeter-wave bands (28/38/60/77 GHz) have already been seen in automotive radars and are starting to surface for 5G applications and beyond. The question is if this success can be translated to technologies beyond 100 GHz and extending up to 1 THz for short-range to long-range communication links. Silicon is not the only contender in the space. In the landscape of integrated technologies ranging from ICs (CMOS, SiGe to III-V) to photonics and other technologies, it is not clear how the pie be divided. This paper will focus on some of the latest advances in silicon-based THz systems and future challenges that span across all levels of abstraction in this uncharted frequency spectrum.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420424","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}

OTFS is a novel modulation scheme based on multiplexing information symbols over localized pulses in the delay-Doppler signal representation. Traditional OFDM modulation operates in the frequency-time domains. In contrast, OTFS modulation operates in the delay spread-Doppler plane domains, which are related to frequency and time by the symplectic Fourier transform (similar to a two-dimensional discrete Fourier transform). OTFS is shown to perform very well under the 5G usage scenarios such as high speed vehicle to vehicle communication with wide Doppler spreads, where the traditional OFDM system performance degrades. Like any other communications system, the OTFS modem is not free from receiver impairments such as DC offset and carrier frequency offset, which affects the channel estimation and hence the decoding process. We study the effects of these receiver impairments on the receiver performance from real time experiments conducted on the implemented OTFS modem in a real indoor wireless channel. We also compare the performance of OTFS modulation and OFDM modulation using the same hardware setup and environment for the real frequency selective and partially emulated doubly selective channel.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131967513","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 considered system model consists of an access point (AP) and a mobile user device (UD) with a random orientation, which makes the instantaneous received SNR random. The distance between the AP and the UD is modeled through the random waypoint (RWP) mobility model, whereas uniform incidence angle is used to model the random orientation of the UD. Novel closed- form expressions for the probability density function and the cumulative distribution function of the instantaneous received SNR are derived. Based on this, closed-form expressions of typical performance measures, such as the outage rate probability (ORP) and the average symbol error probability (SEP) are also derived. The accuracy of the derived expressions are validated through extensive simulations and the effect of mobility and random orientation of the UD on the performance of the system are then evaluated. Our results show that the UD's random orientation degrades the system performance.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128594832","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}

Regardless of the control and non-payload communication and payload communication, the unmanned aerial vehicle (UAV) air-to-ground (AG) channel essentially determine the link performance. In addition, the AG channel presents distinct characteristics in different scenarios. In the mountain scenario, the UAV is generally used to provide communication coverage and collect the data from the ground sensor node (SN). In this paper, an analytical multipath propagation model for UAV AG channel in such a scenario is presented. The path length of the reflections from the mountain is calculated through the geometrical relationship. Moreover, the result turns out that the survival time of the single-bound reflection from the mountain is larger than that of the double-bound reflection. In addition, the propagation mechanism is validated by ray-tracing simulations and the proposed path loss model is more capable of describing the channel behavior than the mostly used two-ray model in AG channels.","PeriodicalId":426086,"journal":{"name":"2019 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125372454","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}
