To the best of our knowledge, these schemes have been developed for narrowband transmission. In this paper, we adapt RSM schemes for outdoor wideband mmWave massive MIMO systems. We consider the downlink of a single user system operating with single carrier RSM and design a low complexity time-domain finite impulse response pre-equalizer to combat the intersymbol interference caused by the wideband transmission, assuming imperfect channel knowledge. We show that receive antenna selection (RAS) is necessary for attaining high spectral efficiency and we suggest fast and efficient RAS algorithm. Simulation results show that the proposed RSM scheme achieves comparable spectral efficiency to the fully digital orthogonal frequency division multiplexing MIMO system with superior energy efficiency.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128069849","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 is particularly designed for applications which rely on real-time augmented vision based on live First Person View (FPV) feed from constrained remote agents like Unmanned Aerial Vehicle (UAV), etc. A-REaLiST ensures low-latency transfer of video and, despite transient losses, enables quick recovery from video freeze/corruption without incurring undue lag. A-REaLiST is an attempt to provide a solution for delay sensitive video streaming where the standard streaming solutions fail. It proposes new extensions to the Representational State Transfer (RESTful) semantics of Constrained Application-layer Protocol (CoAP) to enable efficient real-time streaming of time-series information (including video). Furthermore, A-REaLiST uses a unique integrated approach to maintain the balance amongst QoE, resource-efficiency and loss resilience based on contextual intelligence inferred from instantaneous information segment in flight. With its efficiency confirmed through benchmarking experiments, A-REaLiST reflects the promise to become a standard for streaming over CoAP based RESTful IoT infrastructure.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128104502","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 proposed DDPG-based optimization framework is evaluated by comparing with the well-known RL algorithms, i.e., Deep Q-learning Network and Q-learning.

However, the dense deployment of femtocells brings an unprecedented challenge of introducing severe co-channel interference (CCI), which puts a great limitation on the network performance. Therefore, the interference mitigation problem in UDNs is of great importance. The conflict-graph is the representation of underlying interference constraints of the network and the basis of interference mitigation. Most prior studies construct conflict-graphs based on accurate geographical distance information although it is usually unavailable by the network operators in actual. A more practical association rules based down-link conflict-graph construction approach, which utilizes negative acknowledgement (NACK) data, new data indicator (NDI) data and resource block (RB) allocation data, is proposed in this paper. The relative interference intensities of different interfering sources are determined by the calculated confidence degrees and taken as the edge weights of the constructed conflict-graph. Furthermore, the proposed conflict-graph construction approach is extremely accurate especially for severe interference, which has been verified by simulation results.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134062058","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}
