Abstract[English]
Various aspects of the present disclosure relate to user equipment (UE) radio frequency (RF) calibration requirements. An apparatus, such as a UE, receives a first signal and a second signal at two or more antenna connectors of a multi-antenna receiver, where the first signal and the second signal having different receive gains and different receive phases. The UE reports an estimate of a receive phase offset between the first signal and the second signal. A baseband processor of a UE receives the first signal via a first antenna connector, and receives the second signal via a second antenna connector. The baseband processor compares a receive phase of the first signal to a receive phase of the second signal to determine the estimate of a receive phase offset between the first and second signals. The baseband processor reports the estimate of the receive phase offset between the first and second signals.[French]
Divers aspects de la présente divulgation concernent des exigences d'étalonnage radiofréquence (RF) d'équipement utilisateur (UE). Un appareil, tel qu'un UE, reçoit un premier signal et un second signal au niveau d'au moins deux connecteurs d'antenne d'un récepteur à antennes multiples, le premier signal et le second signal ayant différents gains de réception et différentes phases de réception. L'UE signale une estimation d'un décalage de phase de réception entre le premier signal et le second signal. Un processeur de bande de base d'un UE reçoit le premier signal par l'intermédiaire d'un premier connecteur d'antenne, et reçoit le second signal par l'intermédiaire d'un second connecteur d'antenne. Le processeur de bande de base compare une phase de réception du premier signal à une phase de réception du second signal pour déterminer l'estimation d'un décalage de phase de réception entre les premier et second signaux. Le processeur de bande de base rapporte l'estimation du décalage de phase de réception entre les premier et second signaux.
