以下摘自802.11mac 协议标准 9.2.5.4
A STA that used information from an RTS frame as the most recent basis to update its NAV setting is
permitted to reset its NAV if no PHY-RXSTART.indication is detected from the PHY during a period with a
duration of (2 × aSIFSTime) + (CTS_Time) + aPHY-RX-START-Delay + (2 × aSlotTime) starting at the
PHY-RXEND.indication corresponding to the detection of the RTS frame. The “CTS_Time” shall be
calculated using the length of the CTS frame and the data rate at which the RTS frame used for the most recent
NAV update was received.
按照协议规定,一个节点在收到一个不发给自己的rts后应该设置nav,时间为2 × aSIFSTime) + (CTS_Time) + aPHY-RX-START-Delay + (2 × aSlotTime),
但是很多书上说nav该设置到ack,
请问一个节点在收到一个不发给自己的rts后 到底该如何设置nav?
望达人不吝赐教!!
谢谢
