Title (EN) SOUNDING REFERENCE SIGNAL (SRS) TRANSMIT ANTENNA SELECTION
(FR) SÉLECTION D'ANTENNE D'ÉMISSION DE SIGNAL DE RÉFÉRENCE DE SONDAGE (SRS)
Abstract:
(EN) Methods and apparatuses relate to sounding reference signal (SRS) transmit antenna selection in wireless communication systems. For example, a user equipment (UE) may select, from a set of antennas, a subset of antennas for SRS transmission based on at least one antenna selection parameter. The UE may further transmit, on an uplink communication channel, the SRS using the subset of antennas to a network entity. In some aspects, the at least one antenna selection parameter may include a reference signal receive power (RSRP) value, a signal-to-noise ratio (SNR) value, a spectrum efficiency value, and/or an SNR value and a channel correlation value.
(FR) L'invention concerne des procédés et des appareils en rapport avec la sélection d'antenne d'émission de signal de référence de sondage (SRS) dans des systèmes de communication sans fil. Un équipement d'utilisateur (UE), par exemple, peut sélectionner, à partir d'un ensemble d'antennes, un sous-ensemble d'antennes pour une émission de SRS en se basant sur au moins un paramètre de sélection d'antenne. L'UE peut en outre émettre le SRS sur un canal de communication de liaison montante vers une entité de réseau en utilisant le sous-ensemble d'antennes. Selon certains aspects, lesdits paramètres de sélection d'antenne peuvent comprendre une valeur de puissance de réception de signal de référence (RSRP), une valeur de rapport signal/bruit (SNR), une valeur de rendement spectral et/ou une valeur de SNR et une valeur de corrélation de canal.
