Abstract: A method of method of dynamic channel switching by a station (STA), including: receiving a resource unit (RU) allocation in an initial frame exchange; determining that the STA cannot operate in its operating BW covering a primary channel based upon the RU allocation; switching to secondary channel(s) per an RU allocated to it to carry out communication by the STA during a transmit opportunity (TXOP); carrying out the communication during the TXOP; and switching back to the primary channel no later than an end of the TXOP if detecting that an AP will not do the initial frame exchange with it in the secondary channel(s) within the TXOP.

Abstract: A method and system of exchanging frames between a first multi-link device (MLD) and a second MLD, including: announcing, by the first MLD, a set of links with the second MLD, wherein the set of links includes a primary link and a non-primary link and wherein a single full function radio in the first MLD switches between the primary link and the non-primary link; switching, by the first MLD and second MLD, to the non-primary link when the primary link is busy; exchanging frames between the first MLD and the second MLD; and switching back to the primary link, by the first MLD and the second MLD, when a transmit opportunity (TXOP) of the primary link ends.

Abstract: A method and system including: transmitting, by an access point (AP), a multi-user request to send (MU-RTS) frame requesting a non-AP station (non-AP STA) to respond with a clear to send (CTS) frame on one or more 20 MHz non-primary subchannels; and receiving, by the AP, a CTS frame from the non-AP STA on the one or more 20 MHz non-primary subchannels.
