Title

(EN) EARLY SOUNDING REFERENCE SIGNAL TRANSMISSION ON A SECONDARY CELL

(FR) TRANSMISSION DE SIGNAL DE RÉFÉRENCE DE SONDAGE PRÉCOCE SUR UNE CELLULE SECONDAIRE

Abstract

(EN) Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an active cell, a message triggering transmission of a sounding reference signal (SRS) on a secondary cell (SCell) that is deactivated. The UE may transmit, on the SCell and in response to the message, the SRS. Numerous other aspects are described.

(FR) Divers aspects de la présente invention se rapportent, de façon générale, à la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir, en provenance d'une cellule active, un message déclenchant la transmission d'un signal de référence de sondage (SRS) sur une cellule secondaire (SCell) qui est désactivée. L'UE peut transmettre, sur la SCell et en réponse au message, le SRS. De nombreux autres aspects sont décrits.
