Could someone please help me find (page#) where in the IEEE 802.11 standard it directly says that Access Points are responsible for choosing the channel/frequency to be used and not clients. I know it's in there somewhere but I can't find where it says that in plain text and was hoping maybe someone on here is more familiar with the standard may know.
Channel usage information is provided by the AP to the non-AP STA to recommend channels for noninfrastructure networks or an off-channel TDLS direct link. The non-AP STAs can use the channel usage information as part of channel selection processing for a noninfrastructure network or an off-channel TDLS direct link.
At page 58.
The AP Channel Report element contains a list of channels where a STA is likely to find an AP.
At page 580.
The Channel Switch Announcement element is used by an AP in a BSS, a STA in an IBSS, or a mesh STA in an MBSS to advertise when it is changing to a new channel and the channel number of the new channel.
