高速場景下的大規(guī)模MIMO資源管理研究

近年來,全世界都在抓緊建設(shè)運行速度超過500公里/小時的高速列車。尤其是子彈頭列車和高速列車在中國已被廣泛使用。此外,由于列車的高速移動性,以及人們對高速數(shù)據(jù)服務(wù)的需求日益增加,使得獲取準(zhǔn)確的信道信息和開發(fā)高速鐵路(HSR)通信的高效廣播系統(tǒng)(如可靠性,安全列車運行和乘客通信)成為關(guān)鍵。滿足乘客在高速列車場景下對無線通信的需求是一個具有挑戰(zhàn)性的問題。例如,2017年中國推出世界上最快、最長的高速列車,連接北京和上海兩地,總長達1318公里。此列車最高時速可達500公里/小時,該路線的容量估計約為每天22萬乘客,所有這些乘客都需要穩(wěn)定和高質(zhì)量的互聯(lián)網(wǎng)連接。高速鐵路的發(fā)展給乘客帶來了極大的便利,然而乘客對可靠的無線和數(shù)據(jù)連接的需求也在增加。在過去幾年中,由于智能手機、平板電腦、筆記本電腦和許多其他無線數(shù)據(jù)消費設(shè)備的急劇發(fā)展,數(shù)據(jù)流量呈指數(shù)級增長。隨著全球移動數(shù)據(jù)流量的增長,未來對無線數(shù)據(jù)流量的需求將會更大,預(yù)計到2018年每月增長到15.9艾比特,與2014年相比增長約6倍。此外,估計到2018年時,增加的連接設(shè)備數(shù)量將達到102億。在基站和接入點之間傳輸?shù)臄?shù)據(jù)是來自火車上眾多不同旅客的復(fù)...
