Title
(DE) ÜBERTRAGUNG VON MULTIPLEXIERTEN LOTUNGSREFERENZSIGNALPORTS IN NEW RADIO
(EN) TRANSMITTING MULTIPLEXED SOUNDING REFERENCE SIGNAL PORTS IN NEW RADIO
(FR) TRANSMISSION DE PORTS DE SIGNAL DE RÉFÉRENCE DE SONDAGE MULTIPLEXÉS DANS UNE NOUVELLE RADIO
Abstract
(EN)
Certain aspects of the present disclosure relate to methods and apparatus for transmitting multiplexed sounding reference signal (SRS) ports in communications systems operating according to new radio (NR) technologies. An exemplary method includes obtaining an indication of a technique to use in transmitting sounding reference signals (SRS) via five or more antenna ports in one slot and transmitting the SRS via the five or more antenna ports according to the indicated technique.

(FR)
Selon certains aspects, la présente invention concerne des procédés et un appareil permettant de transmettre des ports de signal de référence de sondage (SRS) multiplexés dans des systèmes de communication fonctionnant selon de nouvelles technologies de radio (NR). Un procédé donné à titre d'exemple comprend l'obtention d'une indication d'une technique à utiliser dans la transmission de signaux de référence de sondage (SRS) par l'intermédiaire de cinq ports d'antenne ou plus dans un créneau et la transmission du SRS par l'intermédiaire des cinq ports d'antenne ou plus selon la technique indiquée.
