Abstract
(EN) A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines CSI. The UE determines whether to send the CSI based on at least one of a timer or a threshold. The UE sends the CSI upon determining to send the CSI. The UE may send the CSI in a MAC header upon determining to send the CSI. When the UE determines whether to send the CSI based on the threshold, the UE may determine whether to send the CSI based on a difference between the CSI and reference CSI. The UE may determine the reference CSI based on at least one of previously reported CSI, fixed CSI, or an MCS of a received data transmission from a base station. The UE may send CSI to the base station in an initial connection setup with the base station.
(FR) L'invention porte sur un procédé, un appareil et un produit programme d'ordinateur pour une communication sans fil. L'appareil peut être un équipement utilisateur (UE). L'UE détermine des informations d'état de canal (CSI). L'UE détermine d'envoyer ou non les CSI sur la base d'au moins l'un d'un temporisateur ou d'un seuil. L'UE envoie les CSI dès la détermination d'envoyer les CSI. L'UE peut envoyer les CSI dans un en-tête MAC dès la détermination d'envoyer les CSI. Lorsque l'UE détermine d'envoyer ou non les CSI sur la base du seuil, l'UE peut déterminer d'envoyer ou non les CSI sur la base d'une différence entre les CSI et des CSI de référence. L'UE peut déterminer les CSI de référence sur la base d'au moins l'un de CSI rapportées précédemment, de CSI fixes, ou d'un MCS d'une émission de données reçues en provenance d'une station de base. L'UE peut envoyer des CSI à la station de base dans une configuration de connexion initiale avec la station de base.
