Indication of multicast control information
A method for indicating a structure of control information for a multimedia broadcast multicast service (MBMS) is provided. The method comprises separating a multicast control channel (MCCH) of an MBMS transmission into a first portion and a second portion and arranging the separated MCCH into a structure wherein the first portion includes the second portion. The method further includes including in a downlink transmission an indicator to indicate the structure is used.
1. A method comprising:
separating by a network access equipment a multicast control channel (MCCH) of a multimedia broadcast multicast service (MBMS) transmission into a first portion and a second portion and arranging the separated MCCH into a structure wherein the first portion directly includes the second portion,
wherein the second portion contains at least two of:
scheduling information for at least one multicast traffic channel (MTCH) portion of the MBMS transmission;
modulation and coding information for at least one MTCH portion of the MBMS transmission; or
a blocked cell list; and
including in a downlink transmission an indicator to indicate that the structure is used.
2. The method of claim 1 , wherein the structure is used when the MBMS is one of a plurality of MBMSs being transmitted by a particular transmitting component.
3. The method of claim 1 , wherein the structure is used when the MBMS is the only MBMS being transmitted by a particular transmitting component.
4. The method of claim 1 , wherein the first portion further includes at least one of:
service advertisement information for the MBMS;
session start information for the MBMS; or
modulation and coding information for the second portion.
5. The method of claim 1 , wherein the indicator is included in a broadcast control channel.
6. The method of claim 1 , wherein the indicator is included in the first portion of the MCCH.
7. A user equipment, comprising:
one or more processors configured to receive 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 having a structure wherein the first portion directly includes the second portion,
wherein the second portion contains at least two of:
scheduling information for at least one multicast traffic channel (MTCH) portion of the MBMS transmission;
modulation and coding information for at least one MTCH portion of the MBMS transmission; or
a blocked cell list; and
the one or more processors further configured to receive an indicator that indicates the structure is used.
8. The user equipment of claim 7 , wherein the first portion further includes at least one of:
service advertisement information for the MBMS;
session start information for the MBMS; or
modulation and coding information for the second portion.
9. The user equipment of claim 7 , wherein the structure is used when the MBMS is one of a plurality of MBMSs being transmitted by a particular transmitting component.
10. The user equipment of claim 7 , wherein the structure is used when the MBMS is the only MBMS being transmitted by a particular transmitting component.
11. The user equipment of claim 7 , wherein the indicator is included in one of:
a broadcast control channel; and
the first portion of the MCCH.
12. A network access equipment in a wireless telecommunications network for transmitting multimedia broadcast multicast service (MBMS) control information, 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 having a structure wherein the first portion includes the second portion,
wherein the second portion contains at least two of:
scheduling information for at least one multicast traffic channel (MTCH) portion of the MBMS transmission;
modulation and coding information for at least one MTCH portion of the MBMS transmission; or
a blocked cell list; and
the one or more processors further configured to promote transmission of an indicator to indicate the structure is used.
13. The network access equipment of claim 12 , wherein the structure is used when the MBMS is one of a plurality of MBMSs being transmitted by the network access equipment.
14. The network access equipment of claim 12 , wherein the structure is used when the MBMS is the only MBMS being transmitted by the network access equipment.
15. The network access equipment of claim 12 , wherein the first portion further includes at least one of:
service advertisement information for the MBMS;
session start information for the MBMS; or
modulation and coding information for the second portion.
16. The network access equipment of claim 12 , wherein the indicator is included in one of:
a broadcast control channel; and
the first portion of the MCCH.
17. The network access equipment of claim 12 , wherein the network access equipment is an enhanced node B.
