Systems and methods for implementing multiple base reference configurations for layer1 / layer2 triggered mobility in a
telecommunications network are provided. The method includes: receiving a first base
reference configuration and an indicator indicating an association between a type / characteristics of a first
cell and the first base
reference configuration from a serving Distributed Unit (gNB-DU), wherein the serving gNB-DU supports the first
cell that serves a
user equipment (UE); sending, during candidate
cell configuration preparation, the first base
reference configuration or the indication to provide a new reference configuration to a target Distributed Unit (target gNB-DU), wherein the target gNB-DU supports a second cell to be prepared as a LTM candidate cell for an LTM
handover; determining whether the first base reference configuration is
usable with a
delta configuration to obtain a full second cell configuration for the second cell; sending a second base reference configuration corresponding to the second cell configuration.
