Abstract

Se describe un método para activar un símbolo de referencia de sondeo aperiódico, una estación base y un equipo de usuario; el método comprende no liberar mediante un equipo de usuario un recurso usado para transmitir un símbolo de referencia de sondeo aperiódico configurado por una estación base para el equipo de usuario, si el equipo de usuario se desincroniza o el equipo de usuario falla en transmitir una solicitud de planificación a la estación base; ejecutar un procedimiento de acceso aleatorio mediante el equipo de usuario; y transmitir mediante el equipo de usuario el símbolo de referencia de sondeo aperiódico en el recurso no liberado usado para transmitir un símbolo de referencia de sondeo aperiódico configurado por una estación base para el equipo de usuario de acuerdo con la información de indicación emitida por la estación base para indicar al equipo de usuario transmitir un símbolo de referencia de sondeo aperiódico si el acceso aleatorio tiene éxito; se hace posible a través de la modalidad que la estación base obtiene rápidamente información de estado de canal de enlace ascendente (CSI) del equipo de usuario (UE) para así planificar rápidamente la transmisión de datos de enlace ascendente del equipo de usuario (UE).
