1. A communication apparatus, configured to be used in a station multi-link device (STA MLD), wherein the communication apparatus comprises:
a processor coupled to a memory configured to store program instructions for execution by the processor, wherein when executing the program instructions, the communication apparatus is configured to:
send a multi-link association request frame; and
receive a multi-link association response frame;
wherein the multi-link association response frame carries link establishment status information, and the link establishment status information indicates link establishment statuses of at least two links that the STA MLD requests to establish, wherein the link establishment status information comprises at least two status code fields, and one of the status code fields indicates an establishment status of one of the at least two links that the STA MLD requests to establish,
wherein the at least two links that the STA MLD requests to establish comprise a transmitted link and at least one non-transmitted link, the transmitted link is a link on which the multi-link association request frame is transmitted, and the non-transmitted link is a link other than the link on which the multi-link association request frame is transmitted.
