Webb19 mars 2024 · The MAC-PHY provides support for a synchronized counter, timestamping of received messages and timestamp capture for transmit messages. This greatly reduces the complexity of the software design, as there is no further hardware support needed to implement time synchronization beyond the MAC-PHY itself. Webb收到PHY的confirm后，MAC会经过一番斟酌，想尽各种办法组一个包最大限度的利用这PSDU_LENGTH字节（但绝不可超过），然后通过PHY-TXSTART.request原语，启动实际的PHY发送。聪明如你一定想到了，这只不过是把填充的责任从PHY推给MAC了而已，实际问题没解决啊。实际上这为解决问题提供了某种程度上的可能性。原因有三：引入 …
