Title
(EN) POWER SAVE PROCEDURES FOR MULTI-LINK AGGREGATION
Abstract
(EN)

A wireless device may dynamically activate and/or inactivate wireless links for multi-link communications. A transmitting wireless device may indicate one or more wireless links to be activated by a receiving wireless device to receive subsequent multi-link transmissions. The indication may be sent over an anchor wireless link, such that the receiving wireless device may monitor the anchor wireless link, with other wireless links in an inactive or low power state, until an indication is received to activate additional wireless links. The receiving wireless device may then activate wireless links identified by the received indication, and receive data from the transmitting device via the multiple links. The activated wireless links may be inactivated upon expiration of a time duration or upon receiving a second indication to inactivate the active links. That is, indications communicated over an anchor wireless channel may identify other wireless links to be activated, inactivated, or maintained.
