dc.description.abstract | 即使只有單用戶進行反饋,延遲通道狀態資訊 (Delayed CSI) 被證明在雙用戶廣播封包消除通道 (PEC) 下,對擴大容量區域方面非常有幫助。然而,反饋鏈路本身需要額外的資源,並可能導致數據傳輸的額外延遲。在這項工作中,我們的目標是研究如何在反饋位數和可靠的前向通信速率之間取得最佳平衡。在我們的模型中,其中一個接收端不提供其 CSI,而另一個接收端可以部分反饋其 CSI 的觀察結果給其他節點。這個模型包括三種不同的反饋模式:交替的單用戶反饋、間歇性的單用戶反饋以及速率受限的單用戶反饋。我們的可達成性成果是從之前研究的機遇式網絡編碼來延伸,使得即使在沒有一直可用的單用戶反饋情況下,仍然可以享受網絡編碼帶來的增益。有趣的是,所有我們修改後的部分單用戶延遲 CSI 的傳輸方式的速率區域,都部分匹配了單用戶延遲 CSI 的容量域。並且匹配的上界是發生在無反饋的用戶端,因為它可以從重傳階段中受益。我們的結果還顯示,即使單用戶只有部分提供反饋,仍然可以實現優於無反饋容量的正容量收益。 | zh_TW |
dc.description.abstract | Delayed channel state information (CSI) feedback was shown to be very helpful in enlarging the capacity region of the two-user broadcast packet erasure channel (PEC), even with single-user feedback. However, feedback link itself requires additional resources and may also cause additional delay to data transmission. In this work, we aim to study how to optimally tradeoff the number of feedback bits and the reliable forward communication rate. In our model, one receiver does not provide its CSI while the other one can partially feeds back its observation of channel state to other nodes. This model includes three different feedback schemes: alternating single-user feedback, intermittent single-user feedback and rate-limited single-user feedback. Our achievability is an extension of previous opportunistic network coding such that the network coding gain can still be enjoyed even when the single-user feedback is not always available. Interestingly, rate regions of our modified schemes for partial single-user delayed CSI partially matches the capacity region of single-user delayed CSI. The matched-bound is in favor of no-feedback user, since it can benefits from the retransmission phase. Our results also reveal that even when the single-user feedback is partially provided, strictly positive capacity benefits can be attained over the no-feedback capacity. | en |
