  • Publication number: 20240365419
    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.

  • Publication number: 20240365300
    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.

  • Publication number: 20240365413
    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.

  • Publication number: 20240260109
    Abstract: Implementations of the present disclosure relate to multi-link communications between multi-link devices, in which a first link between a station of a first multi-link device and an access point of a second multi-link device and a second link between an access point in the first multi-link device and a station in the second multi-link device can be both established. The first link and the second link are combined for an improved multi-link communication with better performance, such as the reduction of latency, an improved power-saving mechanism and the enhanced time synchronization.

  • Publication number: 20240147276
    Abstract: Implementations of the present disclosure relate to link failure detection. In the implementations, an access point (AP) determines a power save mode of each of a plurality of links established between the AP and a station. If at least two links of the plurality of links are in a power save mode, the AP determines a detection time period for detecting signals based on beacon intervals of the at least two links. The AP then transmits detection signals to the station in the at least two links during the detection time period. The AP determines connectivity of the at least two links based on responses to the detection signals received from the station. In this way, all the failed links in power save mode can be efficiently detected, thereby facilitating transmission scheduling between the AP and station.
