(EN) METHOD AND APPARATUS FOR CHANNEL STATE INFORMATION ACQUISITION AND REPORTING IN MOBILE COMMUNICATIONS
(FR) PROCÉDÉ ET APPAREIL D’ACQUISITION ET DE RAPPORT D’INFORMATIONS D’ÉTAT DE CANAL DANS DES COMMUNICATIONS MOBILES
Abstract
(EN)
Various solutions for channel state information (CSI) acquisition and reporting with respect to user equipment and network apparatus in mobile communications are described. An apparatus may enter into a power saving mode. The apparatus may monitor a wake-up indication (WUI) while in the power saving mode. The apparatus may determine whether the WUI is received from a network node. The apparatus may transmit channel quality information to the network node in an event that the WUI is received.
(FR)
L'invention concerne diverses solutions pour l'acquisition et le rapport d'informations d'état de canal (CSI) par rapport à un équipement utilisateur et à un appareil de réseau dans des communications mobiles. Un appareil peut entrer dans un mode d'économie d'énergie. L'appareil peut surveiller une indication de réveil (WUI) tout en étant en mode d'économie d'énergie. L'appareil peut déterminer si la WUI a été reçue d'un noeud de réseau. L'appareil peut transmettre les informations de qualité de canal au noeud de réseau si la WUI a été reçue.
