Title
(EN) SOUNDING REFERENCE SIGNAL TRANSMISSION TO INDICATE A VIRTUAL ANTENNA PORT
(FR) ÉMISSION DE SIGNAL DE RÉFÉRENCE DE SONDAGE POUR INDIQUER UN PORT D'ANTENNE VIRTUEL
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) on a plurality of antenna ports. The UE may transmit the SRS on one or more virtual antenna ports, the one or more virtual antenna ports being based at least in part on the plurality of antenna ports. Numerous other aspects are provided.
(FR)
La présente invention, selon divers aspects, se rapporte de manière générale à la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut émettre un signal de référence de sondage (SRS) sur une pluralité de ports d'antenne. L'UE peut émettre le SRS sur un ou plusieurs ports d'antenne virtuels, le ou les ports d'antenne virtuels reposant au moins partiellement sur la pluralité de ports d'antenne. L'invention se présente également sous de nombreux autres aspects.
