Abstract

Se presentan sistemas y métodos para la configuración e indicación de puertos de señal de referencia de desmodulación (DMRS). Un dispositivo de comunicación inalámbrica puede recibir un mensaje que incluya una indicación de un nodo de comunicación inalámbrica. La indicación puede ser para indicar una pluralidad de puertos DMRS asociados con un código de cobertura ortogonal (OCC) en un mapeo de grupo de multiplexión por división de código (CDM) en una pluralidad de recursos no continuos.
