Abstract

A system is provided for scheduling for a multicast broadcast single frequency network (MBSFN). The system includes a central control configured to promote a plurality of enhanced node Bs (ENBs) transmitting one or more multicast traffic channels (MTCHs). The one or more MTCHs are provided during a variable scheduling period (SP) and include a data portion that contains MBSFN traffic content and a variable scheduling portion that contains scheduling information related to the MBSFN traffic content.

Claims (15)

1. A system for providing scheduling for a multicast broadcast single frequency network (MBSFN) comprising:

a central control configured to promote a plurality of enhanced node Bs (ENBs) transmitting one or more multicast channels (MCHs),

wherein the one or more MCHs includes a scheduling portion followed by a data portion that contains traffic content of multimedia broadcast multicast service (MBMS),

wherein the scheduling portion has a variable length and contains scheduling information related to the traffic content, and

providing secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including scheduling information for each MTCH that includes persistent services.

2. The system of claim 1 , wherein the scheduling information includes at least one of the following: service timing related to the transmission, periodicity, allocated resources, and a service identification (ID), and a modulation and coding information related to the traffic content.

3. The system of claim 1 , wherein the central control is further configured to assign a length of the scheduling portion.

4. The system of claim 3 , wherein the length of the scheduling portion is dynamic over a time period.

5. A network control entity in a wireless telecommunication network for scheduling multimedia broadcast multicast services (MBMS), comprising:

a processor configured to promote transmitting a multicast traffic channel (MTCH) having a substantially constant service rate, the processor further configured to promote a secondary multicast control channel (S-MCCH) providing scheduling information associated with the transmitted MTCH, the processor further configured to promote transmitting a plurality of MTCHs having dynamic service rates, the processor configured to promote providing the plurality of MTCHs having the dynamic service rates and the MTCH having the substantially constant rate during an MCH having a scheduling period (SP) including a data portion and a scheduling portion, the scheduling portion maintaining only the scheduling information for the MTCHs having the dynamic service rates, wherein the scheduling portion has a variable length, and providing secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including scheduling information for each MTCH that includes persistent services.

6. The network control entity of claim 5 , wherein the SP has a variable length.

7. A user equipment to receive a multicast broadcast single frequency network (MBSFN) traffic content, comprising:

a processor configured to receive one or more multicast traffic channels (MTCHs) transmissions provided during a variable scheduling period (SP) and including a data portion that contains MBSFN traffic content and a variable length scheduling portion that contains scheduling information related to the MBSFN traffic content, the processor configured to use the scheduling information in the scheduling portion to receive one or more of the MTCHs; and to receive secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including scheduling information for each MTCH that includes persistent services.

8. The user equipment of claim 7 , wherein the scheduling information includes service timing, periodicity, allocated resources, and a service identification (ID) used to receive one or more of the MTCHs.

9. The user equipment of claim 7 , wherein the user equipment uses the scheduling information further comprising a modulation and coding information related to the MBSFN traffic content used to receive one or more of the MTCHs.
