    摘要： 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.

    摘要： Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine if the paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporary UE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.
