In this paper, we aim to incorporate an enhanced Mobile Broadband (eMBB) slice and an ultra-Reliable Low-Latency Communications (uRLLC) slice in the same substrate network, where the eMBB slice aims to receive a high throughput and the uRLLC slice requires a low transmission delay. To achieve the different requirements, we jointly consider user association and bandwidth orchestration in the substrate network, and formulate the problem as a mixed-integer programming (MIP). We propose two different approaches to solve the MIP, i.e., a high-complexity exhaustive search (ES) algorithm and a low-complexity high probability guarantee heuristic (HPGH) algorithm. Simulation results show that our proposed approach can seek the tradeoff between throughput and transmission delay, and allocate on-demand bandwidth resources dynamically.","PeriodicalId":134773,"journal":{"name":"2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124344369","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}

We predict that UAVs will fly autonomously and use a beaconing system similar to that used today in road and maritime traffic to warn of collisions. For this purpose, UAVs regularly broadcast short beacon messages which include their current positions and trajectories. However, beacon messages may not be received correctly due to congestion on the radio channel. As in vehicular environments, the loss of several successive beacon messages sent by a certain UAV can have dramatic consequences, since conflicting trajectories cannot be identified. In our work, we derive the relation between failures on the communications channel and the probability of collisions between UAVs. Eventually, we show that an ALOHA type beaconing system with a bandwidth of 1 MHz can handle massive UAV scenarios.","PeriodicalId":134773,"journal":{"name":"2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114439345","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 legacy quadrature phase shift keying (QPSK) modulation with different power allocation is applied for bit to symbol mapping of each branch. After superposition of constellations from different branches, user-specific spreading sequence is applied which is used for multi-user interference suppression. At receiver side minimum mean square error (MMSE) elementary signal estimator (ESE) is used for multi-user detection. Due to independent channel decoding and QPSK as constellation where two bits have the same reliability, the quality of the log likelihood ratio for the branch with high power is high whose signals will be successfully decoded first. This will facilitate the decoding of the signals of the branch with low power. Our simulation results show NOMA using multi-branch strategy is superior to its counterpart and thus it is a strong candidate as 5G transmission scheme.","PeriodicalId":134773,"journal":{"name":"2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114945544","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}

Using the example of an autonomous quarry, where self-driving trucks autonomously collect and transport goods, there is a need for multiple wireless sensors collecting data about where and when goods can be collected, while guaranteeing reliable operation of the quarry. The vehicles transfer energy to the wireless sensors within range, forming a cluster. The sensors use this energy to transmit data to the vehicles. Finally, the vehicles relay information to an access point (AP). The AP processes the collected information and synchronize the operation of all vehicles. We propose an interference channel selection policy for the sensors-to-vehicles links and vehiclesto- AP links to improve the reliability of the communications, while enhancing the energy utilization. Accordingly, closed-form expression on how to achieve reliable communication within the considered system is derived and numerical results show that the proposed channel selection strategy not only improves the probability of achieving sufficiently reliable communication but also enhances the energy utilization.","PeriodicalId":134773,"journal":{"name":"2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125815556","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}
