Title
(EN) METHOD FOR RELEASING COMPONENT CARRIERS FOR WIRELESS DEVICE POWER EFFICIENCY
(FR) PROCÉDÉ DE LIBÉRATION DE PORTEUSES COMPOSANTES POUR AMÉLIORER UNE EFFICACITÉ ÉNERGÉTIQUE DE DISPOSITIFS SANS FIL
Abstract
(EN)
A method, network node and wireless device, for releasing component carriers for wireless device power efficiency are provided. According to one aspect, the process includes receiving a component carrier - release assistance indication, CC-RAI, recommendation from the WD, the CC-RAI recommendation recommending release of at least one CC. The process may optionally include releasing at least one of the at least one component carrier. The process may also optionally include transmitting an acknowledgement to the WD acknowledging acceptance or rejection of the CC-RAI recommendation.
(FR)
L'invention concerne un procédé, un nœud de réseau, et un dispositif sans fil (WD), utilisés pour libérer des porteuses composantes (CC) et améliorer une efficacité énergétique de dispositifs sans fil. Selon un aspect, le procédé consiste à recevoir, du WD, une recommandation d'indication d'aide à la libération de porteuses composantes (CC-RAI), la recommandation CC-RAI recommandant de libérer au moins une CC. Le procédé peut également consister à libérer au moins l'une de la ou des porteuses composantes. Le processus peut consister en outre à transmettre, au WD, un accusé de réception accusant l'acceptation ou le refus de la recommandation CC-RAI.
