Title
(EN) ENHANCEMENT OF SOUNDING REFERENCE SIGNAL IN MOBILE COMMUNICATIONS
(FR) REHAUSSEMENT D'UN SIGNAL DE SONDAGE DE RÉFÉRENCE DANS DES COMMUNICATIONS MOBILES
Abstract
(EN)
Various examples and schemes pertaining to enhancement of sounding reference signal (SRS) in mobile communications are described. An apparatus determines to activate one from an SRS configuration set that includes an SRS configuration and at least one enhanced SRS configuration. The apparatus then transmits an SRS to a network node of a wireless network based on activated one from the SRS configuration set.

L’invention concerne, dans divers exemples et modes de réalisation, le rehaussement d'un signal de sondage de référence (SRS) dans des communications mobiles. Un appareil détermine l'activation d'un élément issu d'un ensemble de configuration de SRS comprenant une configuration de SRS et au moins une configuration de SRS rehaussée. L'appareil transmet ensuite un SRS à un noeud de réseau d'un réseau sans fil, sur la base de l'élément activé issu de l'ensemble de configuration de SRS.
