Abstract

La presente invención proporciona un método (700) en un dispositivo de red. El método (700) incluye: transmitir (710) una configuración de ocasión de canal de acceso aleatorio (RACH) a un dispositivo terminal, y recibir (720) un preámbulo de RACH que se transmita desde el dispositivo terminal de acuerdo con la configuración de ocasión de RACH. La configuración de ocasión de RACH comprende una primera indicación de recurso de tiempo que identifica al menos un primer conjunto de recursos de tiempo en el cual el dispositivo terminal puede transmitir un preámbulo de RACH de acuerdo con un primer procedimiento de acceso aleatorio, una primera indicación de recurso de frecuencia que identifica al menos un primer conjunto de recursos de frecuencia en el que el dispositivo terminal puede transmitir el preámbulo de RACH de acuerdo con el primer procedimiento de acceso aleatorio, una segunda indicación de recursos de tiempo que identifica al menos un segundo conjunto de recursos de tiempo en el que el dispositivo terminal puede transmitir un preámbulo de RACH de acuerdo con un segundo procedimiento de acceso aleatorio, y una segunda indicación de recurso de frecuencia que identifica al menos un segundo conjunto de recursos de frecuencia en el que el dispositivo terminal puede transmitir el preámbulo de RACH de acuerdo con el segundo procedimiento de acceso aleatorio.
