Channel is reciprocal

作者:互联网

标题直译为:信道是互惠的
摘录一段文字:
Alternatively, if it can be assumed that the channel is reciprocal, that is, the channel characteristics of interest are the same in the downlink and uplink transmission directions, the network can, by itself, acquire knowledge about relevant downlink channel characteristics by estimating the same characteristics in the uplink direction.

我们的问题是:
1/ 信道是互惠的,意思是说信道是相关的对吗?
2/ 我们的下行信道有这些PBCH、PSS/SSS、PDCCH、PDSCH、DM-RS、CSI-RS、PT-RS,上行信道有这些PUSCH、PUCCH、PRACH、SRS、DM-RS,这些上下行信道彼此之间都是互惠的吗?还是只是某些特定信道之间是互惠的?

另外我理解信道测量和信道互惠是两个不同的概念,信道测量是针对单一信道的,而信道互惠是针对两个信道之间的。
