Title
(EN) TRANSMITTING MULTIPLEXED SOUNDING REFERENCE SIGNAL PORTS IN NEW RADIO
(FR) TRANSMISSION DE PORTS DE SIGNAUX 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)
L'invention concerne, dans certains aspects, des procédés et un appareil de transmission de signaux de référence de sondage (SRS) multiplexés par le biais de ports dans des systèmes de communication fonctionnant selon des technologies de nouvelle radio (NR). Un procédé donné à titre d'exemple consiste à obtenir une indication d'une technique à utiliser dans la transmission de signaux de référence de sondage (SRS) par le biais d'au moins cinq ports d'antenne dans un créneau; et à transmettre ces SRS par le biais desdits au moins cinq ports d'antenne selon la technique indiquée.
