Abstract

A method for providing control information for a multimedia broadcast multicast service (MBMS) in network access equipment is provided. The method includes separating a multicast control channel of an MBMS transmission into a first portion and a second portion, placing in the first portion information related to the second portion, and placing in the second portion information related to receiving a multicast traffic channel portion of the MBMS transmission.

Claims (48)

1. A method for providing control information for a multimedia broadcast multicast service (MBMS) in network access equipment, comprising:

separating a multicast control channel (MCCH) of an MBMS transmission into a first portion and a second portion;

placing in the first portion information related to the second portion, wherein information in the first portion comprises modulation and coding information of the second portion; and

placing in the second portion information related to receiving a multicast traffic channel (MTCH) portion of the MBMS transmission,

wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission is at least one of:

scheduling information for at least one MTCH portion of the MBMS transmission; or

modulation and coding information for at least one MTCH portion of the MBMS transmission.

2. The method of claim 1 , wherein the information in the first portion related to the second portion includes one of:

information in the second portion related to receiving the MTCH portion of the MBMS transmission; and

a pointer to a location of the information in the second portion related to receiving the MTCH portion of the MBMS transmission.

3. The method of claim 2 , wherein the information in the first portion includes the pointer to the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is one of a plurality of MBMSs being transmitted in a particular single frequency network.

4. The method of claim 3 , wherein the information in the first portion includes a plurality of pointers to a plurality of sets of information in the second portion, each of the plurality of sets of information related to one of the plurality of MBMSs.

5. The method of claim 1 , wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission further comprises a blocked cell list.

6. The method of claim 1 , wherein the information in the first portion directly includes the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is the only MBMS being transmitted in a particular single frequency network.

7. The method of claim 1 , wherein the information in the first portion further comprises at least one of:

service advertisement information for the MBMS; and

session start information for the MBMS.

8. A user equipment, comprising:

one or more processors configured to promote receiving a multicast control channel (MCCH) of a multimedia broadcast multicast service (MBMS) transmission, the MCCH comprising a first portion and a second portion, the first portion including information related to the second portion, wherein information in the first portion comprises modulation and coding information of the second portion, and the second portion including information related to receiving a multicast traffic channel (MTCH) portion of the MBMS transmission, wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission is at least one of:

scheduling information for at least one MTCH portion of the MBMS transmission; or

modulation and coding information for at least one MTCH portion of the MBMS transmission.

9. The user equipment of claim 8 , wherein the information in the first portion related to the second portion further comprises at least one of:

service advertisement information for the MBMS; and

session start information for the MBMS.

10. The user equipment of claim 8 , wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission further comprises a blocked cell list.

11. The user equipment of claim 8 , wherein the information in the first portion directly includes the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is the only MBMS being transmitted in a particular single frequency network in which the MBMS is being transmitted.

12. The user equipment of claim 8 , wherein the information in the first portion includes a pointer to the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is one of a plurality of MBMSs being transmitted in a particular single frequency network.

13. The user equipment of claim 12 , wherein the information in the first portion includes a plurality of pointers to a plurality of sets of information in the second portion, each of the plurality of sets of information related to one of the plurality of MBMSs.

14. A network access equipment in a wireless telecommunications network for transmitting a multimedia broadcast multicast service (MBMS), comprising:

one or more processors configured to promote transmission of a multicast control channel (MCCH) associated with a transmission of the MBMS, the MCCH comprising a first portion and a second portion, the first portion including information related to retrieving information in the second portion, wherein information in the first portion comprises modulation and coding information of the second portion, and the second portion including information related to receiving a multicast traffic channel (MTCH) portion of the MBMS transmission, wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission is at least one of:

scheduling information for at least one MTCH portion of the MBMS transmission; or

modulation and coding information for at least one MTCH portion of the MBMS transmission.

15. The network access equipment of claim 14 , wherein the information in the first portion directly includes the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is the only MBMS being transmitted in a particular single frequency network.

16. The network access equipment of claim 14 , wherein the information in the first portion includes a pointer to the information in the second portion related to receiving the MTCH portion of the MBMS transmission when the MBMS is one of a plurality of MBMSs being transmitted in a particular single frequency network.

17. The network access equipment of claim 16 , wherein the information in the first portion includes a plurality of pointers to a plurality of sets of information in the second portion, each of the plurality of sets of information related to one of the plurality of MBMSs.

18. The network access equipment of claim 14 , wherein the information in the first portion further comprises at least one of:

service advertisement information for the MBMS; and

session start information for the MBMS.

19. The network access equipment of claim 14 , wherein the information in the second portion related to receiving the MTCH portion of the MBMS transmission further comprises a blocked cell list.

20. The network access equipment of claim 14 , wherein the network access equipment is an enhanced node B.

21. A method for providing control information for a multimedia broadcast multicast service (MBMS) in network access equipment, comprising:

separating a multicast control channel (MCCH) of an MBMS transmission into a first portion and a second portion;
