Abstract
Enhancement of multicast-broadcast multimedia services is disclosed by providing multiple layers that may carry additional or enhanced information. 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.
Claims15
A method of wireless communication, comprising:
- transmitting a multicast-broadcast control message according to a schedule of multicast-broadcast control transmissions in a multicast-broadcast transmission scheduling period, wherein the multicast-broadcast control message indicates a base layer and an enhancement layer being part of a same multicast-broadcast single frequency network (MBSFN) area, wherein the multicast-broadcast control message is a single multicast-broadcast control message that transmitted via a single multicast control channel (MCCH) that is shared by the base layer and the enhancement layer, and wherein base control information for the base layer and enhanced control information for the enhanced layer are included in the shared, single multicast-broadcast control message;
- transmitting a base layer multicast-broadcast service over a first multicast-broadcast channel;
- and
- transmitting an enhancement layer multicast-broadcast service over a second multicast-broadcast channel.
An apparatus configured for wireless communication, the apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor,
- wherein the at least one processor is configured:
- to transmit a multicast-broadcast control message according to a schedule of multicast-broadcast control transmissions in a multicast-broadcast transmission period, wherein the multicast-broadcast control message indicates a base layer and an enhancement layer being part of a same multicast-broadcast single frequency network (MBSFN) area, wherein the multicast-broadcast control message is a single multicast-broadcast control message that is transmitted via a single multicast control channel (MCCH) that is shared by the base layer and the enhancement layer, and wherein base control information for the base layer and enhanced control information for the enhanced layer are included in the shared, single multicast-broadcast control message;
- to transmit a base layer multicast-broadcast service over a first multicast-broadcast channel;
- and
- to transmit an enhancement layer multicast-broadcast service over a second multicast-broadcast channel.
