The disclosure discloses a method and device for receiving an MBMS by a UE in carrier aggregation, including that: a User Equipment (UE) with MBMS capability determines all Component Carriers (CC) that can be received by the UE at the UE's geographic location; the UE determines an MBMS-bearing CC in the all CCs; and the UE receives the MBMS from the MBMS-bearing CC. By the disclosure, the problem of incapability of the UE to receive the MBMS from the CC due to the network side not knowing the requirement of the UE for receiving the MBMS can be solved.
