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 (30)

1. A method implemented by a processor of a central control in a wireless telecommunication network, the method comprising:

promoting a plurality of enhanced node Bs (ENBs) transmitting one or more multicast channels (MCHs),

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

wherein the scheduling portion in the one or more MCHs has a variable length and contains first scheduling information related to the traffic content, wherein the first scheduling information at least includes a scheduling period related to the data portion and an allocation of resources related to the data portion; and

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

2. The method of claim 1 , wherein the first scheduling information further includes a modulation and coding information related to the traffic content.

3. The method of claim 1 , further comprising the central control assigning a length of the scheduling portion.

4. The method of claim 3 , wherein the length of the scheduling portion is dynamically changed over time.

5. A method implemented by a processor of an enhanced node B (ENB) in a wireless telecommunication network, the method comprising:

transmitting at least one multicast channel (MCH) having a scheduling portion immediately followed by a data portion that contains traffic content of multimedia broadcast multicast service (MBMS), wherein the scheduling portion in the at least one MCH has a variable length and contains first scheduling information related to the traffic content, wherein the first scheduling information at least includes a scheduling period related to the data portion and an allocation of resources related to the data portion; and

transmitting secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including second scheduling information for each MTCH.

6. The method of claim 5 , wherein the first scheduling information further includes a modulation and coding information related to the traffic content.

7. A method implemented by a processor of a user equipment, the method comprising:

receiving one or more multicast channels (MCHs) transmissions including a scheduling portion immediately followed by a data portion that contains traffic content of multimedia broadcast multicast service (MBMS), wherein the scheduling portion in the one or more MCHs has a variable length and contains first scheduling information related to the traffic content, wherein the first scheduling information at least includes a scheduling period related to the data portion and an allocation of resources related to the data portion; and

receiving secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including second scheduling information for each MTCH.

8. The method of claim 7 , wherein the first scheduling information further includes a modulation and coding information related to the traffic content.

9. The method of claim 8 , further comprising the user equipment using the modulation and coding information related to the traffic content to receive one or more of the MTCHs.

10. A user equipment comprising:

a processor configured to:

receive one or more multicast channels (MCHs) transmissions including a scheduling portion immediately followed by a data portion that contains traffic content of multimedia broadcast multicast service (MBMS), wherein the scheduling portion in the one or more MCHs has a variable length and contains first scheduling information related to the traffic content, wherein the first scheduling information at least includes a scheduling period related to the data portion and an allocation of resources related to the data portion; and

receive secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including second scheduling information for each MTCH.

11. The user equipment of claim 10 , wherein the first scheduling information further includes a modulation and coding information related to the traffic content.

12. The user equipment of claim 11 , wherein the user equipment is configured to use the modulation and coding information to receive the at least one MTCH.

13. An enhanced node B (ENB) in a wireless telecommunication network, the ENB comprising:

a processor configured to:

transmit at least one multicast channel (MCH) having a scheduling portion immediately followed by a data portion that contains traffic content of multimedia broadcast multicast service (MBMS), wherein the scheduling portion in the at least one MCH has a variable length and contains first scheduling information related to the traffic content, wherein the first scheduling information at least includes a scheduling period related to the data portion and an allocation of resources related to the data portion; and

transmit secondary multicast control scheduling information and at least one multicast traffic channel (MTCH), the secondary multicast control scheduling information including second scheduling information for each MTCH.

14. The ENB of claim 13 , wherein the first scheduling information further includes a modulation and coding information related to the traffic content.

15. The ENB of claim 13 , wherein the processor is further configured to assign a length of the scheduling portion.

16. The ENB of claim 15 , wherein the length of the scheduling portion is dynamically changed over time.
