Claim Text:
1. A User Equipment (UE), the UE comprising: a transceiver configured to receive a Radio Resource Control (RRC) message from a Master enhanced NodeB (MeNB), wherein the RRC message comprises a dedicated random access resources configuration for the UE to perform random access to a cell associated with a Secondary enhanced NodeB (SeNB) for a purpose of an addition of the SeNB, and an identification of the cell where the random access is to be performed; and a controller, coupled to the transceiver, configured to, responsive to receiving the RRC message, command the Media Access Control (MAC) to trigger the random access for the addition of the SeNB to the cell with the identification indicated in the RRC message with the random access resources indicated in the RRC message, wherein the MeNB is an eNB that the UE connects to initially and that acts as mobility anchor, wherein the SeNB is an eNB providing additional radio resources for the UE, which is not the MeNB, and wherein the dedicated random access resource configuration includes a random access preamble and a physical random access channel transmission occasion.
