Abstract

Una estación base (102), que comprende una primera antena (111) para transmitir una primera señal piloto; una segunda antena (112) para transmitir una segunda señal piloto; una tercera antena (113) para transmitir una tercera señal piloto; y una cuarta antena (114) para transmitir una cuarta señal piloto. La estación base se configura para transmitir información de potencia de señal piloto para indicar valores de potencia a un equipo de usuario (104), UE, que recibe la información de potencia de señal piloto. La información de potencia de señal piloto comprende: un primer valor de potencia que corresponde a la primera señal piloto, un segundo valor de potencia que corresponde a la segunda señal piloto, un tercer valor de potencia que corresponde a la tercera señal piloto, y un cuarto valor de potencia que proporciona información con respecto a al menos dos señales piloto de desmodulación.
