Abstract
Various techniques and schemes pertaining to ultra-high reliability (UHR) multi-link direct link operation in wireless communications are described. A first non-access point (non-AP) multi-link device (MLD) establishes multiple links as multi-link direct links with a second non-AP MLD. The first non-AP MLD also maintains a multi-link association with an AP MLD. The first non-AP MLD communicates with the second non-AP MLD over one or more links of the multiple links in a multi-link direct link operation.

A method, comprising:
- establishing, by a processor of a first non-access point (non-AP) multi-link device (MLD), multiple links as multi-link direct links with a second non-AP MLD;
- maintaining, by the processor, a multi-link association with an AP MLD;
- and
- communicating, by the processor, with the second non-AP MLD over one or more links of the multi-link direct links in a multi-link direct link operation,
- wherein the multi-link direct links comprise at least:
- a first link between a first non-AP station (STA) affiliated with the first non-AP MLD and a first AP affiliated with the AP MLD;
- a second link between a second non-AP STA associated with the second non-AP MLD and the first AP affiliated with the AP MLD;
- and
- a primary multi-link direct link established between the first non-AP MLD and the second non-AP MLD among the multi-link direct links that is in an active state, and
- wherein the establishing of the multiple links as the multi-link direct links comprises establishing a multi-link off-channel direct link between the first non-AP STA affiliated with the first non-AP MLD and the second non-AP STA associated with the second non-AP MLD such that the first link and the second link enter a doze state responsive to the establishing of the multi-link off-channel direct link, and
- wherein the communicating comprises causing one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link between the first non-AP MLD and the second non-AP MLD, to enter the active state for communication between the first non-AP MLD and the second non-AP MLD by:
- transmitting, to the second non-AP MLD and without involving the AP MLD, a request to cause the one or more other links, of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link, to enter the active state;
- and
- receiving, from the second non-AP MLD and without involving the AP MLD, a confirmation for causing the one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link, to enter the active state.

A method, comprising:
- establishing, by a processor of an access point (AP) multi-link device (MLD), multiple links as multi-link direct links in a multi-link association with a first non-AP MLD and a second non-AP MLD;
- and
- communicating, by the processor, with the first non-AP MLD and the second non-AP MLD over one or more links of the multi-link direct links in a multi-link direct link operation,
- wherein the multi-link direct links comprise at least:
- a first link between a first non-AP station (STA) affiliated with the first non-AP MLD and a first AP affiliated with the AP MLD;
- a second link between a second non-AP STA associated with the second non-AP MLD and the first AP affiliated with the AP MLD;
- and
- a primary multi-link direct link established between the first non-AP MLD and the second non-AP MLD among the multi-link direct links that is in an active state, and
- wherein the establishing of the multiple links as the multi-link direct links comprises establishing a multi-link off-channel direct link between the first non-AP STA affiliated with the first non-AP MLD and the second non-AP STA associated with the second non-AP MLD such that the first link and the second link enter a doze state responsive to the establishing of the multi-link off-channel direct link, and
- wherein the communicating comprises causing one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link between the first non-AP MLD and the second non-AP MLD to enter the active state for communication between the first non-AP MLD and the second non-AP MLD by:
- transmitting, to the second non-AP MLD and without involving the AP MLD, a request to cause the one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link, to enter the active state;
- and
- receiving, from the second non-AP MLD and without involving the AP MLD, a confirmation for causing the one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link, to enter the active state.

An apparatus, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform, as a first non-access point (non-AP) multi-link device (MLD), operations comprising:
- establishing, via the transceiver, multiple links as multi-link direct links with a second non-AP MLD;
- maintaining, via the transceiver, a multi-link association with an AP MLD;
- and
- communicating, via the transceiver, with the second non-AP MLD over one or more links of the multi-link direct links in a multi-link direct link operation,
- wherein the multi-link direct links comprise at least:
- a first link between a first non-AP station (STA) affiliated with the first non-AP MLD and a first AP affiliated with the AP MLD;
- a second link between a second non-AP STA associated with the second non-AP MLD and the first AP affiliated with the AP MLD;
- and
- a primary multi-link direct link established between the first non-AP MLD and the second non-AP MLD among the multi-link direct links that is in an active state, and
- wherein the establishing of the multiple links as the multi-link direct links comprises establishing a multi-link off-channel direct link between the first non-AP STA affiliated with the first non-AP MLD and the second non-AP STA associated with the second non-AP MLD such that the first link and the second link enter a doze state responsive to the establishing of the multi-link off-channel direct link, and
- wherein the communicating comprises causing one or more other links of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link between the first non-AP MLD and the second non-AP MLD, to enter the active state for communication between the first non-AP MLD and the second non-AP MLD by:
- transmitting, to the second non-AP MLD and without involving the AP MLD, a request to cause the one or more other links-of the multi-link direct links, comprising the multi-link off-channel direct link and being other than the primary multi-link direct link, to enter the active state;
