Abstract

Se proporciona un método, nodo de red y dispositivo inalámbrico para asignar un canal de control de enlace descendente físico corto, sPDCCH, a elementos de recursos de una cuadrícula de tiempo-frecuencia para lograr una de alta diversidad de frecuencia y asignación de frecuencia condensada. De acuerdo con un aspecto, un método incluye determinar los recursos de tiempo-frecuencia disponibles para ser configurados como grupos de elementos de recursos cortos, sREGs, configurando sREGs dentro de un bloque de recursos físicos, PRB, para asignar el sPDDCH a los elementos de recursos. El número de sREG depende de varios símbolos de múltiplex de división de frecuencia ortogonal, OFDM, del sPDCCH. Cada sREG abarca un símbolo OFDM.
