Three timescales are considered, namely short-term (2022‘ish), medium-term (2025'ish), and long-term (2030‘ish). The evolution of these KPIs is analyzed by accounting for forecasts on the emerging use cases and their requirements together with assumptions on the pace of wireless technology advancements. Being intrinsically predictive, we cannot assert with certainty the values of the target KPIs and the shortlisting of the Top-10 wireless technology trends. It is, however, aimed at driving discussions and collecting feedback over the next decade. Future refinement is therefore expected as the 5G NR evolution journey progresses towards 6G.","PeriodicalId":385212,"journal":{"name":"2020 2nd 6G Wireless Summit (6G SUMMIT)","volume":"35 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114025476","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 existing sub-harmonic mixer, used previously in direct conversion transceiver, is applied in a sliding-IF mixer architecture. Sub-harmonic mixer with sliding IF architecture is envisioned to further reduce the need of higher LO frequency for upconversion. In this aspect, two architectures are studied by spectral analysis and further verified through circuit simulator. The first has a problem with overlapping sidebands, making it unsuitable for non-symmetrical double sideband modulations. On the other hand, the second architecture manages to up-convert signals up to fo, using a single LO frequency of fo/3.","PeriodicalId":385212,"journal":{"name":"2020 2nd 6G Wireless Summit (6G SUMMIT)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124267019","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}

This paper addresses efficient acquisition of sparse sources through quantized noisy compressive measurements where the encoder and decoder are realized by deep neural networks (DNNs). We devise a DNN based quantized compressed sensing (QCS) method aiming at minimizing the mean-square error of the signal reconstruction. Once trained offline, the proposed method enjoys extremely fast and low complexity decoding in the online communication phase. Simulation results demonstrate the superior rate-distortion performance of the proposed method compared to a polynomial-complexity QCS reconstruction scheme.","PeriodicalId":385212,"journal":{"name":"2020 2nd 6G Wireless Summit (6G SUMMIT)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115176636","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}

Regulators in the 5G era have introduced a variety of spectrum management approaches that allow the deployment of new cellular networks including traditional exclusively nationwide licensing, local licensing and unlicensed approaches involving varying levels of spectrum sharing. The upcoming 6G era in the 2030s will face new challenges resulting from the ever-increasing variety of considered spectrum bands for 6G with drastically different propagation characteristics and the increasing fragmentation of spectrum management approaches. This paper provides an overview of spectrum management for mobile communication networks including the most recent 5G spectrum decisions.

To achieve those requirements, a novel distributed and autonomous network architecture for 6G is proposed with the following features. The network will be globally converged by integrating multiple access technology and introducing new protocol. Meanwhile, the network will become highly distributed and flat to improve scalability, which is inspired by bionics behavior. Additionally, fully autonomous design will be enabled by pervasive distributed intelligence. We also discussed the promising technologies to realize the mentioned features.
