Abstract: Downlink spectral capacity of an eMBMS cell to be maximized for the eMBMS users. In one embodiment, supplementary eMBMS cells may be used together with a primary cell, in which the supplementary eMBMS cells broadcast only eMBMS content and the primary cell is used for uplink and downlink signaling. The primary cell may perform signaling for the corresponding supplementary cells. In this manner, signaling relating to configuring of the eMBMS cells may be offloaded to the non-eMBMS primary cell and eMBMS specific services can be fully utilized from the eMBMS cells. In a second embodiment, an eMBMS cell may be a standalone eMBMS cell that is not associated with a primary cell. In this embodiment, self-contained eMBMS signaling is defined. Additionally, eMBMS data may be broadcast in specified MBSN subframes. In this manner, a device, such as an eMBMS-only device, can independently receive eMBMS services.
