Abstract

Se proporciona un aparato terminal y un método de comunicación capaces de mejorar la fiabilidad y la eficacia de frecuencia en un caso en el que la transmisión se realiza por formación de haces. Se incluyen un receptor configurado para recibir una DMRS, DCI, y un PDSCH, y una unidad de decodificación configurada para decodificar el PDSCH, en donde la DCI incluye un indicador de configuración de transmisión (TCI) y el número de puertos de antena de DMRS, el TCI es información que indica un filtro de recepción espacial para recibir la DMRS, el PDSCH incluye un bloque de transporte, y en un caso en el que se indican dos de los TCI y el número de puertos de antena de DMRS es menor o igual que un número estipulado, y que la DCI incluye una configuración de un bloque de transporte, el PDSCH transmitido desde una parte de los puertos de antena de DMRS se recibe basado en un primer TCI, y el PDSCH transmitido desde un resto de los puertos de antena de DMRS se recibe basado en un segundo TCI para decodificar el un bloque de transporte.
