MULTI-LINK CHANNEL ACCESS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18216921 Titled 'MULTI-LINK CHANNEL ACCESS'
Simplified Explanation
In a wireless local area network (WLAN) system, there is a device called a transmitting multi-link device (MLD). This device has multiple links, with one link being the primary link and the others being non-primary links.
When the MLD wants to transmit a PPDU (Physical Protocol Data Unit) on a non-primary link, it may choose to defer the transmission. This means that even if the back-off counter of the non-primary link reaches zero (which is a mechanism used to avoid collisions with other devices), the MLD will still wait to transmit as long as the back-off counter of the primary link has not reached zero.
During this deferral, the back-off counter of the non-primary link will be kept at zero, meaning it will not be reset or incremented. This allows the MLD to prioritize the transmission on the primary link and avoid potential collisions or interference.
Overall, this abstract describes a mechanism in a WLAN system where a transmitting multi-link device can defer the transmission on a non-primary link as long as the back-off counter of the primary link has not reached zero.
Original Abstract Submitted
In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.
