Gbps高速無(wú)線通信系統(tǒng)MAC層協(xié)議研究的中期報(bào)告摘要：隨著移動(dòng)通信技術(shù)和需求的不斷發(fā)展，Gbps級(jí)別的無(wú)線通信系統(tǒng)成為了未來的發(fā)展趨勢(shì)和研究熱點(diǎn)。在這樣的背景下，MAC層協(xié)議的設(shè)計(jì)和研究顯得尤為重要。本文闡述了Gbps高速無(wú)線通信系統(tǒng)MAC層協(xié)議研究的中期進(jìn)展，包括設(shè)計(jì)思路、技術(shù)路線、關(guān)鍵技術(shù)等方面。首先介紹了Gbps高速無(wú)線通信系統(tǒng)的MAC層設(shè)計(jì)目標(biāo)和要求，包括高吞吐量、低時(shí)延、高可靠性等。為了實(shí)現(xiàn)這些目標(biāo)，本文提出了一種基于時(shí)間分割的MAC協(xié)議設(shè)計(jì)思路，并詳細(xì)闡述了該設(shè)計(jì)思路的實(shí)現(xiàn)方法和相關(guān)技術(shù)，包括幀結(jié)構(gòu)設(shè)計(jì)、時(shí)隙分配、鏈路調(diào)度等。其次，本文重點(diǎn)介紹了MAC層關(guān)鍵技術(shù)研究進(jìn)展，包括：1.高速無(wú)線傳輸技術(shù)的支持：在Gbps高速無(wú)線通信系統(tǒng)中，需要使用高速無(wú)線傳輸技術(shù)來保證數(shù)據(jù)傳輸?shù)乃俣群头€(wěn)定性。因此，本文介紹了現(xiàn)有的高速無(wú)線傳輸技術(shù)，并分析了其在Gbps無(wú)線通信系統(tǒng)中的應(yīng)用。2.時(shí)隙分配和鏈路調(diào)度算法：針對(duì)基于時(shí)間分割的MAC協(xié)議設(shè)計(jì)思路，本文提出了一種基于貪心算法的時(shí)隙分配和鏈路調(diào)度算法，并在NS3仿真平臺(tái)上進(jìn)行了測(cè)試和驗(yàn)證。3.多用戶并發(fā)訪問技術(shù)：在高速無(wú)線通信系統(tǒng)中，多用戶并發(fā)訪問技術(shù)是保證系統(tǒng)吞吐量和性能的關(guān)鍵技術(shù)。因此，本文介紹了現(xiàn)有的多用戶并發(fā)訪問技術(shù)，并分析了其在Gbps無(wú)線通信系統(tǒng)中的應(yīng)用。最后，本文總結(jié)了Gbps高速無(wú)線通信系統(tǒng)MAC層協(xié)議研究的中期進(jìn)展，并展望了未來的研究方向和任務(wù)。關(guān)鍵詞：Gbps無(wú)線通信系統(tǒng)；MAC層協(xié)議；時(shí)間分割；高速無(wú)線傳輸技術(shù)；時(shí)隙分配；鏈路調(diào)度；多用戶并發(fā)訪問技術(shù)。Abstract:Withthecontinuousdevelopmentofmobilecommunicationtechnologyanddemand,Gbps-levelwirelesscommunicationsystemhasbecomethetrendandresearchhotspotinthefuture.Inthiscontext,thedesignandresearchofMACprotocolforGbpshigh-speedwirelesscommunicationsystemareparticularlyimportant.ThispaperexpoundsthemidtermprogressofMAClayerprotocolresearchinGbpshigh-speedwirelesscommunicationsystem,includingdesignideas,technicalroutes,andkeytechnologies.Firstly,thedesigngoalsandrequirementsofMAClayerforGbpshigh-speedwirelesscommunicationsystemareintroduced,includinghighthroughput,lowlatency,andhighreliability.Toachievethesegoals,thispaperproposesatimedivision-basedMACprotocoldesignidea,andelaboratesontheimplementationmethodandrelatedtechnologies,includingframestructuredesign,slotallocation,andlinkscheduling.Secondly,thispaperfocusesontheresearchprogressofkeytechnologiesinMAClayer,including:1.Supportforhigh-speedwirelesstransmissiontechnology:InGbpshigh-speedwirelesscommunicationsystem,high-speedwirelesstransmissiontechnologyneedstobeusedtoensurethespeedandstabilityofdatatransmission.Therefore,thispaperintroducestheexistinghigh-speedwirelesstransmissiontechnologyandanalyzesitsapplicationinGbpswirelesscommunicationsystem.2.Slotallocationandlinkschedulingalgorithm:TakingtheMACprotocoldesignideabasedontimedivisionasanexample,thispaperproposesaslotallocationandlinkschedulingalgorithmbasedongreedyalgorithm,andtestsandverifiesitontheNS3simulationplatform.3.Multi-userconcurrentaccesstechnology:Inhigh-speedwirelesscommunicationsystem,multi-userconcurrentaccesstechnologyisthekeytechnologytoensuresystemthroughputandperformance.Therefore,thispaperintroducestheexistingmulti-userconcurrentaccesstechnologyandanalyzesitsapplicationinGbpswirelesscommunicationsystem.Finally,thispapersummarizesthemidtermprogressofMAClayerprotocolresearchinGbpshigh-speedwirelesscommunicationsystem,andlooksforwardtofutureresearchdirectionsandtasks.Keywords:Gbpswirelesscommunicationsystem;
