Claim Text:
1. A method to perform a control signaling by a user equipment in a coordinated multi-point (CoMP) system, the method comprising: receiving first control information scrambled using a CoMP radio network temporary identifier (RNTI) assigned to the CoMP system; receiving, through a data channel decoded by the user equipment using the first control information, a cell information block (CIB), generated by a CoMP enhanced node b (eNB) of a plurality of CoMP eNBs in the CoMP system, containing associated cell information on each of the plurality of CoMP eNBs included in the CoMP system; storing the associated cell information contained in the CIB to refer to the associated cell information in a handover procedure; receiving second control information that is scrambled using a cell RNTI (C-RNTI) of the user equipment and that indicates a target cell for the handover procedure; and performing the handover procedure to the target cell based on the second control information, wherein the user equipment communicates with the plurality of CoMP eNBs and the plurality of CoMP eNBs is scheduled to communicate with the user equipment by the CoMP eNB, and wherein the second control information contains a CoMP cell index to identify the target cell within the CoMP system.
