Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that indicates a change from an evolved universal mobile telecommunications system (UMTS) terrestrial radio access (E-UTRA) packet data convergence protocol (PDCP) to a New Radio (NR) PDCP, wherein the message includes an instruction to perform an intra-cell handover; generate one or more security keys based at least in part on receiving the message that includes the instruction to perform the intra-cell handover; and communicate using the one or more security keys after the intra-cell handover is performed. Numerous other aspects are provided.
