Abstract
Disclosed is a method by which a multi-link device (MLD) of a wireless communication system transmits a frame. The MLD transmits a request frame for mapping between a traffic identifier (TID) and a link, and the request frame can include: first mapping information for establishing a mapping relationship between one or more TIDs from among a plurality of TIDs and one or more links; and information related to the number of the one or more TIDs for which mapping with the one or more links is requested. Thereafter, the MLD can receive a response frame in response to the request frame, and first remaining TIDs that exclude the one or more TIDs from among the plurality of TIDs maintain, to be valid, a previously established mapping relationship with a link, or a default mapping relationship is applied, and, for the first remaining TIDs, a mapping relationship with a specific link may not be indicated by the first mapping information.
