1. A method of a wireless device, comprising:
receiving at least one radio resource control (RRC) message comprising:
a parameter indicating that duplication is configured for one or more data radio bearers (DRBs) including a first DRB, the first DRB corresponding to a first logical channel and a second logical channel,
first mapping restrictions of the first logical channel to at least one first cell, and
second mapping restrictions of the second logical channel to at least one second cell;
receiving a media access control (MAC) control element comprising duplication activation bits for the one or more DRBs, the duplication activation bits having a fixed size of one octet, wherein an i-th duplication activation bit in the duplication activation bits indicates whether a duplication for a DRB of an i-th DRB identifier in an ordered list of DRB identifiers is activated, and wherein the ordered list of the DRB identifiers is an ascending ordered list of DRB identifiers of the one or more DRBs;
in case that a duplication activation bit corresponding to the first DRB is set to a first value indicating that a duplication of the first DRB is activated, transmitting a first packet and a duplicated packet of the first packet; and
in case that the duplication activation bit corresponding to the first DRB is set to a second value indicating that the duplication of the first DRB is deactivated, lifting the first mapping restrictions and the second mapping restrictions.
