Currently serving cell change is triggered by L3 measurements and is done by RRC signalling triggered Reconfiguration with Synchronisation for change of PCell and PSCell, as well as release\/add for SCells when applicable. All cases involve complete L2 (and L1) resets, leading to longer latency, larger overhead and longer interruption time than beam switch mobility. The goal of L1\/L2 mobility enhancements is to enable a serving cell change via L1\/L2 signalling, in order to reduce the latency, overhead and interruption time.\nIn Rel-17 Conditional PSCell change (CPC)\/Conditional PSCell addition (CPA), a CPC\/CPA-configured UE has to release the CPC\/CPA configurations when completing random access towards the target PSCell. Hence the UE doesn\u2019t have a chance to perform subsequent CPC\/CPA without prior CPC\/CPA reconfiguration and re-initialization from the network. This will increase the delay for the cell change and increase the signaling overhead, especially in the case of frequent SCG changes when operating FR2. Therefore, MR-DC with selective activation of cell groups aims at enabling subsequent CPC\/CPA after SCG change, without reconfiguration and re-initialization on the CPC\/CPA preparation from the network. This results in a reduction of the signalling overhead and interrupting time for SCG change.\nCurrently, CHO and MR-DC cannot be configured simultaneously. This limits the usefulness of these two features when MR-DC is configured. In Rel-18 specific mechanisms for CHO and MR-DC to be configured simultaneously including following enhancements:\n1) L1\/L2 based inter-cell mobility;\n2) NR-DC: Selective CG activation (at least for SCG) (RRC) without reconfiguration and re-initiation of CPC\/CPA;\n3) CHO with target MCG, target SCG;\n4) CHO with target MCG, candidate SCGs for CPC\/CPA.\nRAN#94-e approved a Rel-18 Work Item NR_Mob_enh2 (latest WID in RP-231475) to address the above demand for Further NR mobility enhancements.
