Direct narrationはHe said, “Let’s postpone the meeting until Friday.”で、indirectはHe suggested that we should postpone the meeting until Friday.かHe said to postpone the meeting until Friday.等で間違いないと思います。
もう一つは正直no ideaですが。。Free indirect speechかな。。→ He suggested. Let’s postpone the meeting until Friday.
それか、first person (I said, “Let’s postpone the meeting until Friday.”)か自由直接話法とか？（Let’s postpone the meeting until Friday.）かもしれません。
