Abstract

A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for handover using pre-configured gaps in a 5G NR network, and to cause the UE to perform operations including decoding first configuration signaling received from a first base station associated with a first cell. The first configuration signaling configures a legacy measurement gap. The UE decodes second configuration signaling received from the first base station. The second configuration signaling configures an NCSG measurement gap. The UE performs cell measurements of a second cell associated with a second base station during one of the legacy measurement gap or the NCSG measurement gap. The UE encodes the cell measurements for transmission to the first base station. The UE decodes a handover instruction from the first base station. The handover instruction is based on the cell measurements.
