The layers may be defined over a single multicast-broadcast single frequency network (MBSFN) area, or, in additional aspects, may be defined having separate MBSFN areas. When the network provides a single MBSFN area for each layer, control information for the layers may be transmitted in a scheduled multicast-broadcast control message, while when the layers are nested with separate MBSFN areas, the control information for each layer may be transmitted in a separate multicast-broadcast control message."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signaling support for multi-layer MBSFN","description":"Enhancement of multicast-broadcast multimedia services is disclosed by providing multiple layers that may carry additional or enhanced information.
