Title (EN) UPLINK POWER CONTROL FOR WIRELESS COMMUNICATION
(FR) COMMANDE DE PUISSANCE DE LIAISON MONTANTE POUR UNE COMMUNICATION SANS FIL
Abstract:
(EN) Certain aspects of the present disclosure provide closed loop and open loop power control techniques for each antenna of the user equipment (UE). The access point may measure the received signals from each antenna of the user equipment, calculate a power adjustment parameter for each antenna of the UE, and transmit the parameters to the UE. The UE may use the adjustment parameters to determine the transmit power value for each antenna. In addition, the UE may measure the path loss for each antenna and update the transmit power per antenna based on the path loss and other parameters.
(FR) Certains aspects de la présente invention portent sur des techniques de commande de puissance en boucle fermée et en boucle ouverte pour chaque antenne de l'équipement utilisateur (UE). Le point d'accès peut mesurer les signaux reçus à partir de chaque antenne de l'équipement utilisateur, calculer un paramètre d'ajustement de puissance pour chaque antenne de l'équipement utilisateur et transmettre les paramètres à l'UE. L'UE peut utiliser les paramètres d'ajustement pour déterminer la valeur de puissance d'émission pour chaque antenne. De plus, l'UE peut mesurer la perte de trajet pour chaque antenne et mettre à jour la puissance d'émission par antenne sur la base de la perte de trajet et d'autres paramètres.
