Channel switching for multi-link devices

A non-access point (AP) multi-link device (MLD) (non-AP MLD), comprising:

• stations (STAs), each comprising a transceiver configured to communicate over a link with a corresponding AP of an AP MLD;
• and
• a processor operably coupled to the transceiver, the processor configured to:
• receive, via at least one of the transceivers, information associated with a channel switching operation from the AP MLD, the information based on data associated with a moving average of one or more parameters that are associated with channel congestion or link quality;
• determine, based on the information, to initiate the channel switching operation, wherein a first STA of the non-AP MLD will switch from a first channel to a second channel on a first link;
• instruct the first STA of the non-AP MLD to communicate with a first AP of the AP MLD on the second channel over the first link when communication over the second channel would be improved compared to communication over the first channel;
• and
• instruct the first STA of the non-AP MLD to continue communicating with the first AP of the AP MLD on the first channel over the first link when communication over the second channel would not be improved compared to communication over the first channel.

A method for wireless communication performed by a non-access point (AP) multi-link device (MLD) that comprises stations (STAs), the method comprising:

• communicating, via a first STA, over a link with a corresponding AP of an AP MLD;
• receiving information associated with a channel switching operation from the AP MLD, the information based on data associated with a moving average of one or more parameters that are associated with channel congestion or link quality;
• determining, based on the information, to initiate the channel switching operation, wherein a first STA of the non-AP MLD will switch from a first channel to a second channel on a first link;
• instructing the first STA of the non-AP MLD to communicate with a first AP of the AP MLD on the second channel over the first link when communication over the second channel would be improved compared to communication over the first channel;
• and
• instructing the first STA of the non-AP MLD to continue communicating with the first AP of the AP MLD on the first channel over the first link when communication over the second channel would not be improved compared to communication over the first channel.
