REPORTING APERIODIC CSI VIA PUCCH
(FR)
CRÉATION DE RAPPORT DE CSI APÉRIODIQUES VIA UN PUCCH
Abstract:
(EN)
Reporting aperiodic channel state information (A-CSI) via a physical uplink control channel (PUCCH) is disclosed. A UE receives a configuration to report aperiodic channel state information (A-CSI) using physical uplink control channel (PUCCH). The UE can report lightweight A-CSI via short/long PUCCH or may report heavy A-CSI via short/long PUCCH. The UE receives a trigger signal for PUCCH-based A-CSI reporting either by a dedicated downlink grant or by a group common DCI. When triggered via a DCI-based trigger, the PUCCH resource can be either a resource used for HARQ-ACK feedback, e. g., short PUCCH; or a semi-static configured PUCCH resource, e. g., either short PUCCH or long PUCCH. When triggered via a group common DCI-based trigger, the PUCCH resource can be either semi-statically configured, or dynamically indicated.
(FR)
L'invention concerne la création d'un rapport d'informations d'état de canal apériodiques (A-CSI) via un canal de commande physique en liaison montante (PUCCH). Un UE reçoit une configuration pour rapporter des informations d'état de canal apériodiques (A-CSI) à l'aide d'un canal de commande physique en liaison montante (PUCCH). L'UE peut rapporter des A-CSI légères via un PUCCH court/long ou peut rapporter des A-CSI lourdes via un PUCCH court/long. L'UE reçoit un signal de déclenchement pour la création d'un rapport d'A-CSI basé sur un PUCCH, soit par un octroi de liaison descendante dédié, soit par un DCI commun de groupe. Lorsqu'elle est déclenchée via un signal de déclenchement basé DCI, la ressource PUCCH peut être une ressource utilisée pour une rétroaction HARQ-ACK (un PUCCH court, par ex.) ou une ressource PUCCH configurée de manière semi-statique (un PUCCH court ou long, par ex.). Lorsqu'elle est déclenchée via un signal de déclenchement basé DCI commun de groupe, la ressource PUCCH peut être configurée de manière semi-statique ou indiquée de manière dynamique.
