In this paper, research and standardization activities related non-linear precoding for 3GPP are described. Implementation, performance evaluation of nonlinear precoding and analysis of 3GPP specification impact are presented in this paper. Both system and UE throughput evaluation results, conducted at both 5GHz and 30GHz, demonstrate that non-linear precoding yield superior performance compared to linear precoding. In addition, two novel non-linear precoding based transmission schemes which require lower computational complexities than conventional non-linear precoding schemes are proposed. The first scheme separates UEs into linearly precoded and nonlinearly precoded UEs, reducing computational complexities required by non-linear precoding. The second scheme is a precoding scheme which intentionally introduces inter-UE interference through linear precoding and implements nonlinear precoding to remove inter-UE interference; multi-user diversity gain and reduction in computational complexity are obtained simultaneously. Finally, new abstraction performance metrics for the proposed schemes are presented. The simulation results demonstrate that the proposed methods outperform linear precoding techniques and offer a tradeoff between computational complexity and throughput performance.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126877382","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}

For achieving such requirements, the services should be shifted towards the vicinity of the users as much as possible. In this scope, Multi-access Edge Cloud (MEC) will play a tremendous role in 5G technology by hosting various services close to the end-users. Thanks to the MEC technology, different services could be placed near the User Equipment (UEs) for enabling very low latency and high bandwidth communication, which is required by real-time applications, such as mobile broadband in vehicles that are characterized by high UEs mobility. In order to ensure the service requirement in terms of low-latency communication, those services should follow (i.e., service migration) the user mobility by placing them always at the closest MEC. Motivated by the evolution of real time applications, we propose and evaluate three different mechanisms to improve the end user experience by using container-based live migration paradigm. In these approaches, we leverage the follow-me edge concept for enabling lightweight live migration. While the two first solutions take into consideration the mobile users' paths (e.g., cars), the third one is oblivious to the users' paths. The obtained results demonstrate the efficiency of these solutions compared to prior works.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"88 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130763350","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}

Then how to guarantee the availability of these services is coming correspondingly owing to the error prone nature of softwares. Resource redundancy has been seen as an efficient way. Moreover, the resource orchestration of softwares is more flexible than that of physical machines. Therefore, how to design a resource efficient solution to assure the availability of network services in NFV environment has been attracting attentions in academics and industries. Network services are usually finished by service function chains (SFC) in NFV, and an SFC is composed by several virtual network functions (VNF) in order. In this paper, we study the availability aware VNF deployment problem considering users' SFC requests (SFCr). To improve the resource efficiency, a Joint Deployment and Backup scheme taking advantage of Shared Redundancy (JDBSR) is proposed. Through the thorough simulations, the results show that our solution has a great advantage over the benchmarks.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133869104","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}

Since IPv6 supports packet sizes larger than the IEEE 802.15.4 maximum frame size, 6LoWPAN WG defined an adaptation layer by standardizing several documents such RFC 4944, RFC 6282 and RFC 6775. RFC 4944 describes the frame format for transmission of IPv6 packets and it defines mechanisms for header compression and fragmentation. RFC 6282 updates RFC 4944, however, it does not reconsider the 6LoWPAN fragment forwarding method. Indeed, considering that IEEE 802.15.4 comes with a Maximum Transmission Unit (MTU) size of 127 bytes, while a IPv6 datagrams with a 1280 byte MTU, an IPv6 packet could be fragmented into more than ten fragments at the 6LoWPAN adaptation layer. Then, using the 6LoWPAN route-over mesh network, the fragmented 6LoWPAN packet must be reassembled at every hop, which eventually causes latency, congestion, interference and packet losses. In this paper, we first provide a thorough background on RFC 4944. We then detail the potential fragment forwarding issues when employing the route over scheme. Finally, we present the ongoing efforts at the IETF to address the undesired issues.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129742672","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}
