1. A method, carried out by a terminal device, for handling a radio link failure (RLF), the method comprising:
sending duplicated data packets to a network device on a first carrier and a second carrier over a radio interface between the terminal device and the network device, wherein the first carrier is a secondary component carrier, and wherein the first carrier and the second carrier are aggregated carriers; and
sending an RLF indication information to the network device in accordance with a determination that an RLF event occurred on the first carrier, wherein the RLF indication information indicates that the RLF event occurred,
wherein the RLF indication information comprises a first indication information corresponding to the first carrier on which the RLF event occurred, and
wherein the first carrier is used to send a data packet from a first logical channel.
