Abstract
Se propone un método de esquema de transmisión basado en señal de referencia de desmodulación (DMRS) de dos capas (Categoría=2). La matriz de precodificación en un RE de datos puede ser representada como AxB. La matriz de precodificación en la señal de referencia específica de UE DMRS es A. La matriz B es la matriz de ciclado de co-fase. Al aplicar la matriz de ciclado de co-fase propuesta B para el esquema de transmisión basado en DMRS de Categoría=2, la relación de EPRE de PDSCH con EPRE de DMRS es igual a 0 dB, como se requiere por la especificación de LTE. Además, cuando la potencia de DMRS sigue la matriz de precodificación A, se mejora el rendimiento de estimación de canal de UE.
