Abstract: A method for handling a radio link failure (RLF) is described. The method includes sending, by a terminal device, duplicated data packets to a network device on a first carrier and a second carrier. Thereafter, upon determining that an RLF occurred on one of the first carrier and the second carrier, the terminal device sends RLF indication information to the network device. The RLF indication information indicates that the RLF event occurs on the first carrier, the second carrier, or the first carrier and the second carrier.

Abstract: A communication method and apparatus is provided. The method includes: camping on a first cell by a terminal device. The method further includes: determining, by the terminal device, to access a second cell in response to: receiving a paging message from the first cell, determining that there is to-be-transmitted uplink information, or determining that there is a to-be-transmitted non-multicast service. A frequency of the first cell is different from a frequency of the second cell. The terminal device may not perform uplink transmission or may receive only a multicast service in the first cell so that energy consumption of cell measurement and beam selection is reduced. In addition, resource utilization of a communication system can be improved through flexible deployment.
