An objective of the present disclosure is to provide schemes, concepts, designs, techniques, methods and apparatuses pertaining to EHT multi-link operation management. Under various proposed schemes in accordance with the present disclosure, a unified multi-link operating mode signaling may be utilized for EHT multi-link operation management. For instance, under various proposed schemes, a multi-link STA may use one or more selected links instead of all of its supported multiple links, thereby resulting in reduced energy consumption and reduced cost. Regarding reduced energy consumption, the multi-link STA may operate on one (and no more than one) link of its multiple links. Regarding reduced cost, the multi-link STA may support one (and no more than one) active link (e.g., the multi-link STA needs no more than one encoder/decoder). When a basic service set (BSS) is congested, the multi-link STA may operate on one (and no more than one) link of the multiple links as performance gain with multiple links tends to be quite small.

In one aspect, a method may involve a processor of an apparatus receiving, from an access point (AP), a frame comprising a multi-link configuration information element (IE) that indicates one or more enabled links as a subset of one or more supported links for a traffic identifier (TID). The method may also involve the processor transmitting, to the AP, data over at least one of the one or more enabled links corresponding to the TID.
