Each link bitmap subfield may indicate the link on which frames corresponding to the TID associated with the link bitmap subfield are sent. For instance, in case a first bit of the link bitmap subfield for TIDm is set to “1”, a first link may be used for sending frames corresponding to TIDm. Similarly, in case an eighth bit of the link bitmap subfield for TIDm is set to “1”, an eighth link may be used for sending frames corresponding to TIDm. Moreover, detailed parameters (e.g., Operating Class and Channel Number) of an Nth link may be exchanged at a multi-link operation setup phase. Furthermore, one or more bits in the link bitmap subfield for a single TID may be set to “1”.
FIG. 2 illustrates an example scenario 200 in accordance with the present disclosure. In scenario 200, for each multi-link STA, a multi-link configuration IE may include a per-STA TID-link mapping information field, which may include a respective AID subfield, a TID bitmap subfield and one or more link bitmap subfields. Each link bitmap subfield may correspond to a respective link of the respective multi-link STA and may indicate one or more enabled links of the respective TID subfield of the respective multi-link STA. Referring to FIG. 2, a link bitmap subfield for a TIDm of a multi-link STA having AIDi is shown to indicate link 1, link 2, link 3 and link 4. Similarly, a link bitmap subfield for a TIDn of a multi-link STA having AIDj is also shown to indicate link 1, link 2, link 3 and link 4.
