METHODS AND APPARATUS FOR INTER-ENB CARRIER AGGREGATION
First Claim
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 to which the random access is to be performed;
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 which the UE connects to initially and which acts as mobility anchor,wherein the SeNB is an eNB providing additional radio resources for the UE, which is not the Master eNB,wherein the dedicated random access resource configuration includes random access preamble and physical random access channel transmission occasion.

Abstract
A method and apparatus for connecting to a secondary enhanced NodeB. A transceiver configured to receive a Radio Resource Control (RRC) message from a Master enhanced NodeB (MeNB). 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 to which the random access is to be performed. 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. The MeNB is an eNB which the UE connects to initially and which acts as mobility anchor.

15. A master enhanced NodeB (MeNB), the MeNB comprising:
-
a transceiver configured to transmit a Radio Resource Control (RRC) message to a user equipment (UE), 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 to which the random access is to be performed; a controller coupled to the transceiver, the controller configured to; receive the dedicated random access resources from at least one of the SeNB and a network node; wherein the MeNB is an eNB which the UE connects to initially and which acts as mobility anchor, wherein the SeNB is an eNB providing additional radio resources for the UE, which is not the Master eNB, wherein the dedicated random access resource configuration includes random access preamble and physical random access channel transmission occasion. - View Dependent Claims (16, 17, 18, 19, 20)
