Abstract
(EN)
Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) within a coverage area of a base station may determine a power control configuration. The first UE may transmit an indication of the power control configuration to a second UE, which may adjust one or more power control parameters based on the indication. The one or more power control parameters may include a target received power, a compensation factor, a downlink path loss between the base station and the first UE, or a combination thereof. The second UE may use the adjusted one or more power control parameters to determine a transmit power and may transmit a message to the first UE with the determined transmit power. In some cases, the second UE may be outside of the coverage area of the base station.

La présente invention concerne des procédés, des systèmes et des dispositifs pour des communications sans fil. Dans certains cas, un premier équipement utilisateur (UE) dans une zone de couverture d'une station de base peut déterminer une configuration de commande de puissance. Le premier UE peut transmettre une indication de la configuration de commande de puissance à un second UE, qui peut ajuster un ou plusieurs paramètres de commande de puissance sur la base de l'indication. Le ou les paramètres de commande de puissance peuvent comprendre une puissance reçue cible, un facteur de compensation, une perte de trajet de liaison descendante entre la station de base et le premier UE, ou une combinaison de ceux-ci. Le second UE peut utiliser le ou les paramètres de commande de puissance ajustés pour déterminer une puissance de transmission et peut transmettre un message au premier UE avec la puissance de transmission déterminée. Dans certains cas, le second UE peut être à l'extérieur de la zone de couverture de la station de base.
