Abstract
A wireless device receives, from a base station, a user equipment (UE) capability enquiry message comprising a radio access technology (RAT) request indicating one or more RAT types, wherein the one or more RAT types comprises a new radio (NR). After receiving the UE capability enquiry message, the wireless device transmits to the base station, a UE capability information message indicating whether the wireless device supports a layer 1 / layer 2 triggered mobility (LTM) for a master cell group (MCG) with a secondary cell group (SCG) change or an SCG addition as part of an LTM execution when an LTM cell switch command is received and whether the wireless device supports an LTM for an MCG with random access channel (RACH) with a dual connectivity (DC) configured.
