1. A user equipment in a wireless communication system which communicates with an electronic device in the wireless communication system via a primary cell and a plurality of secondary cells, the user equipment comprising:
one or more processing circuits configured to perform operations comprising:
determining, for each of the plurality of secondary cells, whether a secondary cell beam failure has happened; and
setting a single media access control-control element MAC CE to notify the electronic device upon determining that the secondary cell beam failure has happened in at least two of the plurality of secondary cells,
wherein the MAC CE comprises at least index information of respective component carriers in which the secondary cell beam failure has happened,
wherein in determining, for each of the plurality of secondary cells, whether the secondary cell beam failure has happened, the one or more processing circuits is further configured to perform operations comprising:
determining, based on a reference signal set q0 for the secondary cell beam failure detection, a secondary cell partial beam failure state in which only a part of reference signals in the q0 are in a beam failure channel condition;
reporting, to the electronic device, information indicating that the part of reference signals are in the beam failure channel condition; and
resetting the q0 based on a message from the electronic device.
 
11. A method for wireless communication in a wireless communication system, the wireless communication system comprising user equipment and an electronic device, the user equipment communicating with the electronic device via a primary cell and a plurality of secondary cells, the method comprising:
determining, for each of the plurality of secondary cells, whether a secondary cell beam failure has happened; and
setting a single media access control-control element MAC CE to notify the electronic device upon determining that the secondary cell beam failure has happened in at least two of the plurality of secondary cells,
wherein the MAC CE comprises at least index information of respective component carriers in which the secondary cell beam failure has happened,
wherein in determining, for each of the plurality of secondary cells, whether the secondary cell beam failure has happened, the method further comprises:
determining, based on a reference signal set q0 for the secondary cell beam failure detection, a secondary cell partial beam failure state in which only a part of reference signals in the q0 are in a beam failure channel condition;
reporting, to the electronic device, information indicating that the part of reference signals are in the beam failure channel condition; and
resetting the q0 based on a message from the electronic device.
 
17. A non-transitory computer readable medium storing a product containing instructions which when executed by a processor performs a method for wireless communication in a wireless communication system, the wireless communication system comprising user equipment and an electronic device, the user equipment communicating with the electronic device via a primary cell and a plurality of secondary cells, the method comprising:
determining, for each of the plurality of secondary cells, whether a secondary cell beam failure has happened; and
setting a single media access control-control element MAC CE to notify the electronic device upon determining that the secondary cell beam failure has happened in at least two of the plurality of secondary cells,
wherein the MAC CE comprises at least index information of respective component carriers in which the secondary cell beam failure has happened,
wherein in determining, for each of the plurality of secondary cells, whether the secondary cell beam failure has happened, the method further comprises:
determining, based on a reference signal set q0 for the secondary cell beam failure detection, a secondary cell partial beam failure state in which only a part of reference signals in the q0 are in a beam failure channel condition;
reporting, to the electronic device, information indicating that the part of reference signals are in the beam failure channel condition; and
resetting the q0 based on a message from the electronic device.
