Abstract

Uno o más nodos transmiten símbolos de CSI-RS en un conjunto de N elementos de CSI-RS, cada elemento de CSI-RS en el conjunto correspondiendo a por lo menos un elemento de recurso en una cuadrícula de tiempo-frecuencia de elementos de recursos. Los nodos seleccionan, de los N elementos de CSI-RS, un primer conjunto de elementos de CSI-RS que serán medidos por un primer dispositivo inalámbrico, el primer conjunto comprendiendo uno o varios de los N elementos de CSI-RS. Los nodos también transmiten, al primer dispositivo inalámbrico, un mensaje que comprende un primer indicador de K bits que identifica el primer conjunto de elementos de CSI-RS, en donde K < N. Los nodos reciben entonces un informe de medición. El primer indicador de K bits es uno de un conjunto predeterminado de indicadores de K bits, en donde cada miembro del conjunto predeterminado de indicadores de K bits corresponde de manera única a un elemento de CSI-RS o grupo de elementos de CSI-RS de entre las N CSI-RS, de acuerdo con una asignación predeterminada.
