Abstract
(EN) In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines a first uplink slot on an uplink carrier for reporting channel state information. The UE determines, on a downlink carrier, a first downlink slot that is an earliest downlink slot overlaps with the first uplink slot. The UE determines a number M based on a numerology of the downlink carrier, M being an integer greater than or equal to 0. The UE measures a reference signal, received no later than a second downlink slot that is a latest valid downlink slot no later than M downlink slots prior to the first downlink slot, to generate the channel state information.
(FR) Un aspect de l'invention concerne un procédé, un support lisible par ordinateur et un appareil. L'appareil peut être un UE. L'UE détermine un premier créneau de liaison montante sur une porteuse de liaison montante pour rapporter des informations d'état de canal. L'UE détermine, sur une porteuse de liaison descendante, un premier créneau de liaison descendante qui est un premier créneau de liaison descendante chevauchant le premier créneau de liaison montante. L'UE détermine un nombre M sur la base d'une numérologie de la porteuse de liaison descendante, M étant un nombre entier supérieur ou égal à 0. L'UE mesure un signal de référence, reçu avant un second créneau de liaison descendante qui est un dernier créneau de liaison descendante valide avant les M créneaux de liaison descendante avant le premier créneau de liaison descendante, pour générer les informations d'état de canal.
