This includes use cases like discrete automation, process automation and intelligent transport systems, which have strong requirements on ultra-reliability, low latency and often also on deterministic date delivery. In contrast to many other IP based services, the industrial services are typically Real-Time Ethernet based. For an efficient support of such Ethernet based services, this paper analyses alternatives to 3GPPs GTP-U/UDP/IP or GRE/IP user plane tunneling used on various interfaces inside the core, the access and between access and core. The proposal of this paper is to avoid IP-based tunneling below the Ethernet end-to-end layer and use Ethernet-over-Ethernet instead. Ethernet over Ethernet can be realized by using IEEE Provider Backbone Bridging (PBB) or the IETF TRansparent Interconnection of Lots of Links (TRILL). This paper compares the GTP-U, GRE, PBB and TRILL approach and gives a recommendation on which alternative to use in a 5G network supporting applications with deterministic traffic requirements.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"12 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":"122715218","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}

In particular, we study the cases of many users sharing the same resources that address application of the the internet of things (IoT). The key feature of contention based multiple access is to serve multiple users at the same time and frequency. With different power levels and user grouping, it can achieve better spectral efficiency over conventional orthogonal multiple access (OMA). However, unlike the OMA system, NOMA results in additional inter-user interference (IUI). It has also been shown that, without proper resource allocation for users in the uplink NOMA, the weak users can always be in outage. In this work, we have developed algorithms on subbands assignment, user grouping, and power allocation for joint optimization of sum rate and fairness. The algorithm allocates resources iteratively to handle the IUI in each iteration. Given a number of $N_{s}$ subbands allocation to each user, we could prevent starvation of poor users, e.g. cell edge users. We have also compare and analyze the sum rate and fairness performance with different combination of $L$ and $N_{s}$. We also find that, by properly limiting the maximum number of subbands each user can use, the system could better exploit multi-user diversity to improve the sum rate and hence the energy efficiency. The numerical simulations are also conducted to verify the results.","PeriodicalId":311896,"journal":{"name":"2018 IEEE Conference on Standards for Communications and Networking (CSCN)","volume":"32 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":"127868840","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}
