Abstract
(EN)
A method for a terminal to transmit a Sounding Reference Signal (SRS) in a wireless communication system according to an embodiment of the present invention comprises: a step for receiving an upper layer message including settings information related to the SRS; a step for receiving downlink control information (DCI) for triggering the transmission of the SRS, wherein the settings information related to the SRS includes a plurality of settings sets related to at least one among the number of transmissions of the SRS, the subframe in which the SRS is to be transmitted, a mapping start symbol of the SRS, and/or the time duration over which the SRS is to be transmitted; and a step for transmitting the SRS on the basis of the DCI, wherein the DCI includes information representing one of the plurality of settings sets. The SRS is characterized by being an aperiodic SRS (AP-SRS) and being repeatedly transmitted in a plurality of subframes through a plurality of contiguous symbols.
(FR)
Selon un mode de réalisation de l'invention, un procédé qui permet à un terminal de transmettre un signal de référence de sondage (SRS) dans un système de communication sans fil comprend : une étape de réception d'un message de couche supérieure comprenant des informations de paramétrage relatives au SRS; une étape de réception d'informations de commande de liaison descendante (DCI) pour déclencher la transmission du SRS, les informations de paramétrage relatives au SRS comprenant une pluralité d'ensembles de paramètres liés à au moins une des nombreuses transmissions du SRS, la sous-trame dans laquelle le SRS doit être transmis, un symbole de début de mappage du SRS, et/ou la durée pendant laquelle le SRS doit être transmis; et une étape de transmission du SRS en fonction des DCI, les DCI comprenant des informations représentant l'un des ensembles de paramètres. Le SRS se caractérise en ce qu'il est un SRS apériodique (AP-SRS) et qu'il est transmis de manière répétée dans une pluralité de sous-trames par l'intermédiaire d'une pluralité de symboles contigus.
