Title
(EN) TRANSMISSION OF UPLINK REFERENCE SIGNALS
(FR) TRANSMISSION DE SIGNAUX DE RÉFÉRENCE EN LIAISON MONTANTE
Abstract
(EN) There is provided mechanisms for transmitting uplink reference signals. A method is performed by a terminal device. The method comprises obtaining, from a network node, a configuration of transmission of the uplink reference signals. The configuration comprises an indication of a first frequency interval in which the uplink reference signals are to be transmitted. The method comprises distributing transmission power available for transmitting the uplink reference signals over the first frequency interval based on channel information for the first frequency interval. The method comprises transmitting the uplink reference signals in accordance with the distributed transmission power.
(FR) L’invention concerne des mécanismes servant à émettre des signaux de référence en liaison montante. Un procédé est exécuté par un dispositif terminal. Le procédé consiste à obtenir, à partir d'un nœud de réseau, une configuration d'émission des signaux de référence en liaison montante. La configuration comprend une indication d'un premier intervalle de fréquence dans lequel les signaux de référence en liaison montante doivent être émis. Le procédé consiste à distribuer une puissance de transmission disponible pour émettre les signaux de référence en liaison montante sur le premier intervalle de fréquence sur la base d'informations de canal pour le premier intervalle de fréquence. Le procédé consiste à émettre les signaux de référence en liaison montante conformément à la puissance d'émission distribuée.
