Abstract: A method for harmonic channel detection is provided. The method comprises receiving, by a first AP working on a first channel, a beacon frame transmitted by a second AP and parsing the beacon frame to obtain information of a second channel indicated in the beacon frame. The method further comprises determining a plurality of candidate harmonic channels and validating that the second channel is one of the candidate harmonic channels. In addition, the method further comprises validating that the beacon frame is transmitted on the second channel based on a sequence number and a TBTT indicated in the beacon frame and discarding the beacon frame. Implementations of the present disclosure can reduce harmonic frames from being reported to a controller at upper layer, and improve the performance of the network.

Abstract: Implementations of the present disclosure relate to packet capture for a multi-link device. In the implementations, an access point (AP) obtains a media access control (MAC) address of a multi-link device (MLD) to be monitored. Further, the AP determines a plurality of links of the MLD to be monitored based on the MAC address. Based on the MAC address of the MLD, the AP captures packets transmitted by the AP MLD on the plurality of links, as a monitor AP. For each of the captured packets, the AP inserts the MAC address of the MLD into an MLD MAC field in a packet capture headroom associated with the packet. In this way, the present disclosure can support flexible packet capture (PCAP) for a specific MLD instead of for a specific link.

Abstract: In implementations of the present disclosure, a retry mechanism for access point multi-link device is provided. An access point (AP) multi-link device (MLD) detects a trigger condition for a retry on a first link. After detecting the trigger condition, the AP MLD further selects a second link from a plurality of links. The AP MLD then selects a retry mode from a plurality of retry modes for the second link, and transmits a retry packet on the second link using the selected retry mode. Implementations of the present disclosure can fully utilize the MLD properties to help speed up the transmissions of the retry frames, and can reduce the channel occupation and increase the channel utilization of the retry frames.
