Abstract

Se proporciona un terminal de usuario capaz de definir adecuadamente una secuencia aplicada a una senal de referencia, etc., en un futuro sistema de comunicacion inalambrica; el terminal de usuario comprende: una unidad de transmision, para transmitir un canal compartido de enlace ascendente y una senal de referencia de demodulacion (DMRS) del canal de enlace ascendente compartido; y una unidad de control, para controlar una secuencia aplicada al DMRS, el control se basa en la longitud maxima del DMRS definida en un parametro de capa superior y / o el numero de simbolos DMRS indicados por la informacion de control del enlace descendente y/o si se ha aplicado el salto de frecuencia.
