1. A method performed by a wireless communications device for handover from a first infrastructure equipment to a second infrastructure equipment, the method comprising:
maintaining a data radio bearer between the wireless communications device and the first infrastructure equipment, the data radio bearer being mapped to quality of service (QOS) flows between the wireless communications device and the first infrastructure equipment via a first mapping, each of the QoS flows being configured to provide a specified quality of service; and
receiving a handover command from the second infrastructure equipment via the first infrastructure equipment,
wherein the wireless communications device connects to the second infrastructure equipment via at least one second radio bearer, and the at least one second radio bearer is mapped to the QoS flows via a second mapping that is different from the first mapping.
