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.

L'invention concerne un dispositif sans fil pouvant activer et/ou inactiver dynamiquement des liaisons sans fil pour des communications à liaisons multiples. Un dispositif sans fil émetteur peut indiquer une ou plusieurs liaison(s) sans fil devant être activée(s) par un dispositif sans fil récepteur afin de recevoir des transmissions à liaisons multiples ultérieures. L'indication peut être envoyée sur une liaison sans fil d'ancrage, de telle sorte que le dispositif sans fil de réception peut surveiller la liaison sans fil d'ancrage, d'autres liaisons sans fil étant dans un état inactif ou de faible puissance, jusqu'à ce qu'une indication soit reçue afin d'activer des liaisons sans fil supplémentaires. Le dispositif sans fil récepteur peut ensuite activer des liaisons sans fil identifiées par l'indication reçue, et recevoir des données en provenance du dispositif émetteur par l'intermédiaire des liaisons multiples. Les liaisons sans fil activées peuvent être inactivées à l'expiration d'une durée ou à la réception d'une seconde indication afin d'inactiver les liaisons actives. Ainsi, des indications communiquées sur un canal sans fil d'ancrage peuvent identifier d'autres liaisons sans fil devant être activées, inactivées ou maintenues.
