Abstract

Se proporcionan un nodo de red, dispositivo inalámbrico, estación base, equipo de usuario y métodos correspondientes. El nodo de red incluye un circuito de procesamiento configurado para: seleccionar un primer conjunto y un segundo conjunto de recursos de señal de referencia en una subtrama y agregar el primer conjunto y el segundo conjunto de recursos de señal de referencia en la subtrama para formar una configuración de agregación por multiplexación por división de código, CDM. El primer conjunto y el segundo conjunto de recursos de señal de referencia en la subtrama satisfacen un criterio temporal de tal manera que cualquiera de los dos elementos de recurso en el primer conjunto y el segundo conjunto de recursos de señal de referencia tengan una separación de tiempo máxima de seis símbolos OFDM. El primer conjunto y el segundo conjunto de recursos de señal de referencia en la subtrama satisfacen un criterio de frecuencia de tal manera que cualquiera de los dos elementos de recurso en el primer conjunto y el segundo conjunto de recursos de señal de referencia tengan una separación de frecuencia máxima de seis subportadoras.
