Abstract

En una red inalámbrica que soporta agregación de portadores de componentes de enlace ascendente, las señales de referencia de sondeo, SRS, se transmiten (62) en un portador de componentes primario de enlace ascendente, UL. Un comando de activación correspondiendo a un portador de componente secundario de UL, SCC, se recibe (64), en respuesta a lo cual el transceptor de recepción determina (65) si tiene información de tiempo válida para el SCC de UL, en donde la información de tiempo válida para el SCC de UL indica que el SCC de UL es UL sincronizado. En respuesta a esta determinación, la transmisión de SRS en el SCC de UL se habilita (66) si el SCC de UL se sincroniza, cuando SRS se configura para el SCC de UL. De alguna manera, la transmisión de SRS en el SCC de UL se prohíbe (68) hasta que el SCC de UL es UL sincronizado.
