A method of transmission of excess data associated with a multicast service is scheduled on another radio communication resource. The multicast service may be MBMS or push-to-talk. The method includes determining, at the eNodeB base station, that an amount of data to be multicast during an upcoming scheduling period exceeds the associated multicast communication resource, and accordingly temporarily allocate additional resources on another multicast service communication resource, or else on resources dedicated to conventional services, or else on both kind of resources simultaneously. The base station transmits an indication to the UE(s) about the additional allocation(s) by using MCH scheduling information, such signaling comprising a logical channel identification, LCID, field.
