One of the main reasons of such interest is the upcoming 5G technology, related to the Internet-of-Things (IoT). In this paper, we present a MATLAB-based link-level simulator for WLAN with still used (IEEE 802.11g/n/ac) and upcoming (IEEE 802.11ah/af) technologies. Realization of the whole WLAN link-level simulator is highly inspired by the recognized Vienna LTE-simulator. As a result, it is possible to join together these simulators to explore the performance of WLAN and LTE, operating in the same radio frequency (RF) band. From the point of future 5G based cellular networks, such exploring is important because different coexistence scenarios can occur between wireless communications systems in the ISM and UHF bands.","PeriodicalId":138269,"journal":{"name":"2016 1st International Workshop on Link- and System Level Simulations (IWSLS)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116413968","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}

Functions such as Coordinated Multi Point, Network Assisted Handover, etc., require a standard connection among nodes to support their operations. The LTE X2 interface meets the above requirements and allows operators to connect nodes for both rel-8 and more advanced (e.g rel-13) functionalities. In this work we describe the modeling of X2 within the SimuLTE system-level simulator. Most research works assume an ideal X2 connection, with null delay and infinite bandwidth. However, the X2 delay and bandwidth do affect the behavior and performance of the aforementioned algorithms. Thus, using CoMP Coordinated Scheduling as a case-study to test X2 functionalities, we show how X2 round-trip delay affects the performance of the CoMP scheduler.","PeriodicalId":138269,"journal":{"name":"2016 1st International Workshop on Link- and System Level Simulations (IWSLS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115089915","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}
