The base station receives, from the terminal, an information element informing the base station of a combination of bands, which the terminal supports for carrier aggregation. The terminal supports MBMS reception on any carrier configurable as a serving cell for the terminal according to the information element. The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS. ## Claims ### Claim 1 A method implemented in a base station of a mobile communication network for supporting a Multimedia Broadcast Multicast Service, MBMS, for a terminal, the method comprising: receiving, at the base station from the terminal, an information element informing the base station of a combination of bands that the terminal supports for carrier aggregation;
