An essential part of the CSMA/CA process is when a packet in an Access Category (AC) waits for an Arbitrary Inter- Frame Space (AIFS) period of time before engaging in the the backoff phase. According to the standard, AIFS values are fixed and deterministic, they do not guarantee strict priority for ACs especially when these values are combined with the Contention Window (CW) size of the backoff phase. On the other hand, the AIFS values are not adjustable, they do not adapt to the current status of the medium. In this paper, we propose two algorithms for AIFS value assignment, the Strict Priority Algorithm (SPA) and the Adaptive AIFS Algorithm (A3). With SPA, the AIFS values are fixed, but they are determined according to a mathematical formula that ensures strict priority level among the ACs. With A3, the AIFS values are adaptively changing depending on the value of the collision probability. AIFS still maintains a strict priority level assignment among the ACs.","PeriodicalId":375803,"journal":{"name":"2017 IEEE 86th Vehicular Technology Conference (VTC-Fall)","volume":"38 14","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133783014","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}

However, this highly restricts the number of users simultaneously served. In this paper, a pilot reuse within a single cell DM-MIMO system is proposed to serve more users than the available pilot sequences. The reuse in this strategy is applied so that maximum achievable sum-rate is satisfied with the constraint of predefined pilot resource. On this basis, two users in different subcells separated by a large distance and satisfying a specific signal to interference plus noise ratio (SINR) level can share the same pilot sequence. An expression for SINR is derived for any pair of users who use the same pilot. Based on this expression, an algorithm is proposed to choose which pairs of users are able to use the same pilot with the constraint of satisfying the minimum SINR required for these users. The simulation results demonstrate that the uplink achievable sum-rate for the proposed strategy is higher than both cases when no pilot reuse or random pilot reuse are considered.","PeriodicalId":375803,"journal":{"name":"2017 IEEE 86th Vehicular Technology Conference (VTC-Fall)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133851740","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 this paper, we focus on the use of UAVs for disaster response. Multiple UAVs equipped with communication terminals can be deployed to construct an airborne network connecting isolated areas. Another use is for real-time video transmission from a UAV to a ground station, using multiple UAVs operating simultaneously by different organizations, e.g., rescue teams, fire departments, broadcasting companies, and so forth. In both cases, frequency resources must be shared efficiently among adjacent UAVs. Thus, we describe a radio resource management system for UAVs. The focus of this paper is data communications, rather than the broader issue of command and control communications. First, we present experimental results from field experiments using WiFi communication terminals that do not have centralized radio resource management functionality. Then, we propose a centralized resource allocation technique that assumes an orthogonal frequency division multiplexing (OFDM)-based communication system, using resource blocks consistent with the long-term evolution (LTE) standard.","PeriodicalId":375803,"journal":{"name":"2017 IEEE 86th Vehicular Technology Conference (VTC-Fall)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352984","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}
