ABSTRACT:
A method for indicating a structure of control information for a multimedia broadcast multicast service (MBMS) is provided. The method comprises separating a multicast control channel (MCCH) of an MBMS transmission into a first portion and a second portion and arranging the separated MCCH into either a first structure wherein the first portion includes at least one pointer to a location of the second structure, or a second structure wherein the first portion directly includes the second portion. The method further includes including in a downlink transmission an indicator to indicate which of the first structure and the second structure is used.
