1. A multi-link communication probe request method implemented by a communication apparatus, comprising:
generating a probe request frame, wherein the probe request frame comprises a first multi-link element, the first multi-link element is used to request link information of an access point multi-link device (AP MLD), the first multi-link element comprises a first link information field, the first link information field comprises a first field, the first field indicates that a non-access point multi-link device (non-AP MLD) requests the AP MLD to feed back complete information or partial information of a first link, and the first link information field corresponds to the first link, and the probe request frame further carries an information element outside the first multi-link element,
wherein when the first link information field of the first multi-link element in the probe request frame does not carry a request element and an extended request element, the non-AP MLD requests to the AP MLD to feed back the complete information of the first link, and
wherein when an element ID of an information element of the partial information is indicated by at least one of the request elements and the extended request element carried in the first link information field of the first multi-link element, the non-AP MLD requests to probe the partial information of the first link, and the partial information of the first link does not inherit from the information element carried in the probe request frame outside the first multi-link element; and
sending, the probe request frame to the AP MLD.
