Abstract

The present disclosure relates to a technique for configuring transmission of a multicast channel carrying scheduling information and data belonging to one or more multicast services, the scheduling information indicating scheduling of the multicast services mapped to the multicast channel. A method embodiment comprises the steps of configuring ( 404 ) the transmission of the scheduling information on the multicast channel based on a scheduling information specific transmission requirement and configuring ( 404 ) the transmission of the data belonging to the one or more multicast services based on a service specific transmission requirement; and signalling ( 406 ) the scheduling information specific transmission requirement and the service specific transmission requirement.

Claims (32)

1. A method implemented by a user equipment (UE), the method comprising:

the UE receiving a first transmission from a network node, the first transmission comprising an indication that a first modulation and coding scheme (MCS) is to be used for a multicast channel (MCH) scheduling information (MSI) transmission;

the UE receiving a second transmission from the network node, the second transmission comprising an indication that a second MCS is to be used for a multicast traffic channel (MTCH) transmission;

the UE receiving the MSI transmission from the network node in a first subframe;

the UE decoding the MSI transmission by applying the first MCS to the MSI transmission, wherein the MSI transmission comprises scheduling information for the MTCH transmission;

the UE receiving the MTCH transmission from the network node in a second subframe; and

the UE decoding the MTCH transmission by applying the second MCS to the MTCH transmission.

2. The method of claim 1 , wherein the first transmission is received via a broadcast control channel (BCCH).

3. The method of claim 1 , wherein the second transmission is received via a multicast control channel (MCCH).

4. The method of claim 1 , wherein the first subframe in which the MSI transmission is received corresponds to a subframe associated with an MCH subframe allocation.

5. The method of claim 4 , wherein the second subframe in which the MTCH transmission is received corresponds to a subsequent subframe after the first subframe corresponding to the MCH subframe allocation.

6. The method of claim 1 , wherein the network node corresponds to an eNodeB.

7. The method of claim 1 , wherein each of the MSI transmission and the MTCH transmission are associated with an MCH.

8. The method of claim 1 , wherein the first MCS and the second MCS are different MCSs.

9. The method as in claim 1 , wherein the first MCS and the second MCS are a same MCS.

10. A user equipment (UE) comprising:

a receiver configured to:

receive a first transmission from a network node, the first transmission comprising an indication that a first modulation and coding scheme (MCS) is to be used for a multicast channel (MCH) scheduling information (MSI) transmission,

receive a second transmission from the network node, the second transmission comprising an indication that a second MCS is to be used for a multicast traffic channel (MTCH) transmission,

receive the MSI transmission from the network node in a first subframe wherein the MSI transmission comprises scheduling information for the MTCH transmission, and

receive the MTCH transmission from the network node in a second subframe; and

a processor configured to:

decode the MSI transmission by applying the first MCS, and

decode the MTCH transmission by applying the second MCS.

11. The UE of claim 10 , wherein the first transmission is received via a broadcast control channel (BCCH).

12. The UE of claim 10 , wherein the second transmission is received via a multicast control channel (MCCH).

13. The UE of claim 10 , wherein the first subframe in which the MSI transmission is received corresponds to a subframe associated with an MCH subframe allocation.

14. The UE of claim 13 , wherein the second subframe in which the MTCH transmission is received corresponds to a subsequent subframe after the first subframe corresponding to the MCH subframe allocation.

15. The UE of claim 10 , wherein the network node corresponds to an eNodeB.

16. The UE of claim 10 , wherein each of the MSI transmission and the MTCH transmission are associated with an MCH.

17. The UE of claim 10 , wherein the first MCS and the second MCS are different MCSs.

18. The UE of claim 10 , wherein the first MCS and the second MCS are a same MCS.
