Claim of US Patent No. 10,694,569

5. A terminal, comprising:a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a base station, a radio resource control (RRC) message including data radio bearer (DRB) configuration information for a duplication, wherein one or more DRBs are configured with the duplication based on the RRC message,
receive, from the base station, a medium access control (MAC) control element (CE) including bitmap information indicating whether to activate a duplication of at least one DRB, and
determine whether to activate the duplication of the at least one DRB among the one or more DRBs configured with the duplication based on the DRB configuration information or the duplication included in the RRC message and the bitmap information included in the MAC CE,
wherein the duplication of the at least one DRB among the one or more DRBs configured with the duplication is activated based on bits included in the bitmap information, and
wherein the bits included in the bitmap are mapped to a sequence of an identifier of the one or more DRBs configured with the duplication based on the DRB configuration information.
