Title
(DE) VERFAHREN UND VORRICHTUNG ZUR ÜBERTRAGUNG VON KLANGREFERENZSIGNALEN IN EINEM MEHRANTENNENSYSTEM
(EN) METHOD AND APPARATUS OF TRANSMITTING SOUNDING REFERENCE SIGNAL IN MULTIPLE ANTENNA SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF DE TRANSMISSION D'UN SIGNAL DE RÉFÉRENCE SONORE DANS UN SYSTÈME PLURI-ANTENNE
Abstract
(EN)
A method and an apparatus of transmitting a sounding reference signal by a user equipment is provided. A user equipment transmits a first sounding reference signal through a first antenna, and transmits a second sounding reference signal through a second antenna. Resources for transmitting the first sounding reference signal and the second sounding reference signal are partially different.

(FR)
Procédé de transmission d'un signal de référence sonore (sound reference signal/SRS) par un équipement utilisateur (UE). Un Equipement utilisateur transmet un premier signal de référence sonore par une première antenne et un second signal de référence sonore par une seconde antenne. Les ressources utilisées pour la transmission du premier signal sonore et les ressources utilisées pour la transmission du second signal sonore sont partiellement différentes.
