Abstract

Se proporciona un método para el acceso aleatorio realizado por una entidad de MAC de un UE. El método incluye: recibir una primera configuración de recuperación de fallo de haz de una primera BWP de UL; recibir una segunda configuración de recuperación de fallo de haz de una segunda BWP de UL; iniciar un primer procedimiento de RA en la primera BWP de UL aplicando al menos un primer parámetro de RA configurado en la primera configuración de recuperación de fallo de haz, cuando un número de casos de fallo de haz que se han recibido desde capas inferiores es mayor o igual a un umbral; cambiar una BWP de UL activa del UE desde la primera BWP de UL a una segunda BWP de UL antes de completar el primer procedimiento de RA; e iniciar un segundo procedimiento de RA en la segunda BWP de UL aplicando al menos un segundo parámetro de RA configurado en la segunda configuración de recuperación de fallo de haz, después de cambiar a la segunda BWP de UL.
