• a second identifier identifying a UE context, and
• receive, from the UE, an indication bit included in a medium access control (MAC) subheader of the first packet, the indication bit indicating that the UE supports inactive data transfer between the UE and the anchor base station;
• identify the anchor base station using at least in part on one or more of the first identifier or the second identifier;
• and
• transmit a second packet to the anchor base station using in part on the indication bit, the second packet including at least a portion of the first packet.
