經有許多多用戶多輸入多輸出的協定已經被提出,這些協定運用了多 天線特性來達到多路傳輸的增益,然而,目前的多點傳輸服務中,現 存的協定像是LTE 和802.11ac 並沒有探索多天線所提供的可能增益, 目前多點傳輸服務都是以最低的傳輸速率來確保所有的用戶端都能成 功接收到服務。這篇論文中,我們提出HybridCast,一種多用戶多輸 入多輸出的協定,可以允許多個單點傳播服務使用共同資源同時和多 點傳輸服務一起傳送,我們利用了多天線所提供的自由度和的連線餘 裕(link margin) 來同時傳送多個單點傳播服務並確保本來的多點傳輸 服務不會受到任何影響及干擾。同時我們也設計了能和現今LTE 和 802.11ac 系統相容的傳輸機制,從實驗和大規模的模擬中,我們展示 了HybridCast 比起一般的單一多點傳輸服務和強制為零波束協定確實 能夠獲得更大的吞吐率的增益。 | zh_TW |
dc.description.abstract | In the future, AP and devices will equip with more antennas. There are several multiuser MIMO (MU-MIMO) protocol have been propose to allow multiple nodes to exploit the MIMO capability by transmitting concurrently. However, in single multicast session transmission, those existing protocol such as LTE and 802.11ac do not utilize the MIMO capability. The current mechanism just use the lowest rate to transmit the multicast session to make sure all clients can receive successfully. This paper introduces HybridCast, a MU-MIMO protocol that enables concurrent multicast session and unicast streams transmission. We fully utilize the degree of freedom (DoF) provided by multiple antenna and available link margin to transmit the unicast streams concurrently while doing no harm to multicast session. We also design the transmitting mechanism which is compatible with current 802.11ac and LET system. We show that HybridCast leverages the link margin and MIMO apability to provide more throughput gain than simple multicast or ZFBF protocol via testbed experiment and large scale simulation. | en |
