Abstract
A method for reporting a beam reception failure, a user equipment and a system, wherein the method includes: obtaining an identifier of a secondary cell where a beam reception fails; selecting another beam as a candidate beam in the secondary cell where the beam reception fails; and encapsulating the identifier of the secondary cell where the beam reception fails and an identifier of the candidate beam into a Media Access Control (MAC) control element, and transmitting the MAC control element out using resource of other cells, wherein the other cells comprise: a primary cell, a primary secondary cell, or other secondary cells where the beam reception fails. Therefore, the identifier of the secondary cell where the beam reception fails and its corresponding candidate beam could be transmitted without using the PRACH and the PUCCH.
