研究了继电器对中继通道中通信延迟的影响。都考虑了解释前向（DF）和放大 - 前向（AF），并将其与不使用继电器的点对点（P2P）方案进行了比较。关于DF和AF是否可以减少与给定可靠性要求传达许多位的延迟的问题。这三个方案的延迟表达式是得出的。尽管DF和AF都使用块传输结构，该结构将信息发送到多个传输块上，但它们都可以达到低于P2P的潜伏期。获得了这种情况的条件。有趣的是，与与P2P相比，与DF和AF达到更高信息理论率的条件相比，这些条件更加严格。
The impact of relaying on the latency of communication in a relay channel is studied. Both decode-forward (DF) and amplify-forward (AF) are considered, and are compared with the point-to-point (P2P) scheme which does not use the relay. The question as to whether DF and AF can decrease the latency of communicating a number of bits with a given reliability requirement is addressed. Latency expressions for the three schemes are derived. Although both DF and AF use a block-transmission structure which sends the information over multiple transmission blocks, they can both achieve latencies lower than P2P. Conditions under which this occurs are obtained. Interestingly, these conditions are more strict when compared to the conditions under which DF and AF achieve higher information-theoretic rates than P2P.
