Due to the densification of the users perspective and massive-access opportunities, how to optimize the multiple users access in UDN is an important and complicated problem. The traditional multi-user access schemes may be no longer suitable. Thus, in this paper, we investigate the multi-user access issue with densely-deployed access points (APs) in UDN. Moreover, to further enhance the system throughput and meet the high rate demands of users, the non-orthogonal multiple access (NOMA) is introduced into UDN. Considering the network densification and newly incorporated technological features, we formulate the multi-user access and corresponding resource allocation problem as an optimization problem to enhance the system throughput. To solve it with low-computation complexity, this complex problem is divided into two sub phases, APs association and resource allocation. First, we propose a matching algorithm to assign proper APs and resource blocks (RBs) to the multiple users. According to the channel state information and data rate requirement, a stable matching among the sets of APs, users and RBs is formed after a limited number of iterations. Then, we allocate the transmit power for associated APs based on NOMA by utilizing the differ convex (DC) programming. Numerical results show that the proposed scheme achieves a better performance compared with exiting schemes.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"52 1","pages":"1364-1369"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83605256","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}

One of the major challenges faced by this technology is the pilot contamination issue where interference from users in the neighboring cells may significantly impact the performance of the channel estimation process. There are different strategies proposed in the literature to overcome the pilot contamination issue. However, most of these works assume perfect knowledge of the noise variance in the channel estimation process which is not the case in realistic systems. In this paper, we study the pilot contamination issue in multi-cell MU-MIMO cellular networks and propose two noise variance estimators; 1) maximum likelihood, and 2) method of moments estimators which can be used for the channel estimation under the pilot contamination. We evaluate the performance of these noise estimators, and the impact of the noise estimation on the channel estimation performance. Further, the existing literature shows that the effects of the pilot contamination on the channel estimation is vanished when the angle-of-arrival of the desired and interfering users do not overlap. Using a pilot assignment strategy from the existing literature, we evaluate channel estimation performance at mmWave frequencies for large antenna array regime considering recently developed 5G channel models. Our simulation results show that under pilot contamination, better channel estimation can be achieved at mmWave bands compared to low frequency scenarios.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"72 1","pages":"61-66"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84545170","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}

CLoc accuracy usually suffers from poor Geometric Dilution of Precision (GDoP) along the dimension orthogonal to the road, due to highly constrained VANET mobility and topology. This paper considers benchmarking and even combining two different approaches to resolve this problem. The first solution accounts for the vehicle's heading, making use of an Inertial Measurement Unit (IMU). The second one assumes prior lane detection, along with associated road information (e.g., lane width stored in a digital map). The data fusion scheme is based on a modified Extended Kalman Filter (EKF) capable of filtering out the unbounded noise process integrated at the gyroscope and/or using lane boundaries to numerically refine the density of posterior state estimates. The proposed strategies are shown to boost the probability to reach an accuracy of 0.5 m from 60% up to 85– 90% in comparison with conventional range-based approaches.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"44 1","pages":"659-664"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84800466","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}

It enables hosts to send data over several interfaces or paths and has use cases on smartphones, datacenters or dual-stack hosts. It has proven to increase bandwidth in these cases while remaining compatible with the existing network infrastructure and applications. However, with the popularity of Online Data-Intensive applications which is under soft real-time constraints (e.g., 200ms), finishing jobs with tight deadlines is more important than bandwidth. In this paper, we propose DMTCP, an MPTCP extension that is deadline-aware and remains high throughput. DMTCP can establish subflows for deadline sensitive flows as soon as possible, and provides guaranteed transmission rates for deadline sensitive flows. It does not need to establish subflows one by one as regular MPTCP does and can establish multiple subflows simultaneously at the beginning of the three-way handshake begins. In addition, when the flow is near deadline, DMTCP will switch to utilize “the quick start” mechanism, and it will send SYN packets carrying data to further reduce flow completion time for deadline sensitive flows. Motivated by existing deadline-aware protocols, we also design a congestion control algorithm dedicated to ensuring deadline sensitive flows' completion. The algorithm can provide guaranteed transmission rates for deadline sensitive flows. When congestion happens, the deadline-aware congestion control algorithm can hold a larger congestion window for a flow with a tighter deadline. Our preliminary results show that DMTCP holds great promise in terms of deadline miss rate and goodput.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"12 1","pages":"681-686"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81686976","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, user mobility is even tricky for UDNs, especially in high-speed cases. While handover issues have been widely studied, the impact of high mobility on resource allocation needs to be further studied. In this paper, we investigate the impact of user mobility on transmit power control (TPC) and propose two kinds of mobility-aware TPC schemes which are adaptive to user's speed intelligently: mobility-aware constant TPC (MC-TPC), mobility-aware sub-slotted TPC (MS-TPC). Investigating the distance distribution between the moving user and its access base station (BS), we derive the analytical expressions of system outage probability (OP) and energy efficiency (EE) in the mobile environment to characterize the performance of the proposed and referenced TPC schemes. Numerical results show that the proposed mobility-aware TPCs significantly improve system reliability in terms of OP and data rate, especially with the proper sub-slots division. Meanwhile, in exchange for high reliability, EE degrades within a reasonable range with the increase of moving speed.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"6 1","pages":"1165-1170"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75908037","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}

An imperfect self-interference (SI) cancellation is assumed at the secondary relay (SR), such that the SI power is proportional to the transmit power of the SR. For the SN with limited power expenditure, a novel joint mode selection and power allocation policy is proposed to maximize the secondary throughput under the constraints of secondary power consumption and a limited average induced interference power at the primary destination. For delay sensitive SN applications, a statistical delay constraint is imposed in which the queue length at the SR can only exceed a specified threshold with a limited probability. In the two proposed policies, the SN decides optimally when to operate in half duplex mode and/or in full duplex mode, and be silent. To avoid data loss in the SN, buffer is used at the SR for data storage. Simulation results show that, for a given interference threshold and statistical delay constraint, the proposed policy outperforms the non-buffer full-duplex, buffer-aided half-duplex, and non-buffer half-duplex policies in terms of the average secondary throughput, the average secondary delay, and the secondary power expenditure.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"53 1","pages":"918-923"},"PeriodicalIF":0.0,"publicationDate":"2017-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74425706","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}
