Abstract

Se describe una disposicion de estacion de base que incluye una disposicion de antena, en donde las señales de enlace ascendente se pesan con pesos de disposicion compleja y las señales de enlace descendente se dirigen, en donde las señales de enlace descendente se dirigen utilizando datos a partir de informacion direccional derivada de las señales de enlace ascendente. También se describe un método de operacion.
