Abstract

Una terminal, de acuerdo con un aspecto de la presente descripción, incluye una sección de control que juzga, sobre la base de si se admite el cambio de puerto de antena entre pares de puertos de antena arbitrarios, la correspondencia entre una información de capacidad de grupo de indicador de matriz de precodificación transmitida (TPMI) y un grupo TPMI, y una sección de transmisión que transmite, sobre la base de la correspondencia, la información de capacidad de grupo TPMI correspondiente a un grupo TPMI para admitir la transmisión a plena potencia. De acuerdo con un aspecto de la presente descripción, es posible controlar adecuadamente la transmisión a plena potencia.
