人生如初见，那该多好？初见时候的美丽和美好，初见时候的心动。不像后来演变成冷
战，陌路，分手，从此以后再也不见。如若没有遇见，就不会伤心，如若没有遇见，就
不会有痛苦。短暂的快乐，后来变成久久散不去的痛苦。在你离开以后，我的生活就是
雾霾天气。
我们在一起，我的手机里面单曲循环着《遇见》，你离开以后我的手机单曲循环着《说
好的幸福呢》是啊，那些说好的以后呢？那些我们说要一起做的事情呢？你都忘了，有
天是不是会和其他的女生说呢？
一个人的夜晚，一个人的周末，一个人的任何时候，我都会单曲循环着《说好的幸福呢
》。然后就泪流成河，过去的一幕幕在眼前一遍遍不断重复。我都忘了你的样子，你的
声音，你的名字，但是却又是那么熟悉。
年轻时候说的以后总是美好的，却是那么遥不可及。后来才发现，美好的是年轻的时候
。后来我们再也没有联系，我也不知道你现在过得好不好。我只知道，我要开始新的生
活，这个新的生活再也没有你了！
你离家以后，我的手机单曲循环《说好的幸福呢》，送给年轻的我们，再见了。

Hi,
In 802.11, Is there any special channel coding used on RTS and CTS,
different from the one used for Data packet?
I think RTS/CTS and Data should use the same coding (if any), since they are
simply the payload of PHY layer data unit.
But I really cannot verify that neither on the internet nor in the standards
. So I have to ask this question here.
Thanks!

hmmm...
Actually, they are different in 11b/g/a, but in original
802.11, they use same coding scheme.
in 802.11b and newer versions, RTS/CTS/ACK always use
basic rate. For example, in 802.11b, there are 4 different
(1, 2, 5.5, and 11mbps) different rates can be chosen
depending on the channel condition. Control frames
always use 1Mbps the basic rate, in order to make sure
that these frames are warranted to be heard.

are
standards
