Abstract:

Disclosed are a user equipment unit in a wireless communication system, an electronic apparatus, a method, and a storage medium. The user equipment unit in a wireless communication system communicates with an electronic apparatus in the wireless communication system by means of a primary cell and multiple secondary cells. The user equipment unit comprises one or more processing circuits. The processing circuit is configured to perform the following operations: determining whether each of the multiple secondary cells experiences a beam failure; and if it is determined that beam failures have occurred on at least two of the multiple secondary cells, setting a medium access control control element (MAC CE) to notify the electronic apparatus of same, wherein the MAC CE at least comprises index information of all component carriers on which beam failures have occurred.
