User equipment and base station participating in packet duplication during handover for NR

A user equipment comprising:

• processing circuitry, which, in operation, generates a user equipment packet duplication status, which includes information on a status of uplink packet duplication to be performed by the user equipment with at least one base station,
• wherein the information on the status of uplink packet duplication is per uplink radio bearer, one or more uplink radio bearers being established between the user equipment and the at least one base station, and
• a transmitter, which, in operation, transmits the generated user equipment packet duplication status to the at least one base station,
• wherein,
• the processing circuitry, when generating the user equipment packet duplication status, determines the status of uplink packet duplication per uplink radio bearer based on configuration information received from the at least one base station,
• the information on the status of uplink packet duplication is in a form of a bitmap including one bit per uplink radio bearer, and
• the status of uplink packet duplication is either activated or deactivated per uplink radio bearer.
