PROBLEM TO BE SOLVED: To provide a method and an apparatus to allocate random access channel (RACH) resources. SOLUTION: The method includes a step of arranging, in user equipment (UE), an uplink (UL) component carrier (CC) set and a downlink (DL) component carrier set for performing carrier aggregation (CA). The method further includes a step of pairing an uplink component carrier in the UL CC set with a downlink component carrier in the DL CC set for performing random access, the uplink component carrier uplink component carrier including random access channel (RACH) resources. The method also includes a step of receiving a random access preamble message on the UL CC from the UE and transmitting a random access response message on the paired DL CC in response to the reception of the random access preamble message during a random access process.
