Multicast channel control information
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.
1. A network node comprising:
a processor configured to:
send a first transmission to one or more user equipment (UE), 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;
send a second transmission, the second transmission comprising an indication that a second MCS is to be used for a multicast traffic channel (MTCH) transmission;
send the MSI transmission in a first subframe, the MSI transmission being modulated by the first MCS, wherein the MSI transmission comprises scheduling information for the MTCH transmission; and
send the MTCH transmission in a second subframe, the MTCH transmission being modulated by the second MCS.
2. The network node of claim 1 , wherein the first transmission is sent via a broadcast control channel (BCCH).
3. The network node of claim 1 , wherein the second transmission is sent via a multicast control channel (MCCH).
4. The network node of claim 1 , wherein the first subframe in which the MSI transmission is sent corresponds to a subframe associated with an MCH subframe allocation.
5. A method implemented by a user equipment (UE), the method comprising:
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;
receiving a second transmission, the second transmission comprising an indication that a second MCS is to be used for a multicast traffic channel (MTCH) transmission;
receiving the MSI transmission in a first subframe, the MSI transmission being modulated by the first MCS, wherein the MSI transmission comprises scheduling information for the MTCH transmission; and
receiving the MTCH transmission in a second subframe, the MTCH transmission being modulated by the second MCS.
6. The method of claim 5 , wherein the first transmission is received via a broadcast control channel (BCCH).
7. The method of claim 5 , wherein the second transmission is received via a multicast control channel (MCCH).
8. The method of claim 5 , wherein the first subframe in which the MSI transmission is received corresponds to a subframe associated with an MCH subframe allocation.
9. A user equipment (UE) comprising:
a processor 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, 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 in a first subframe, the MSI transmission being modulated by the first MCS, wherein the MSI transmission comprises scheduling information for the MTCH transmission; and
receive the MTCH transmission in a second subframe, the MTCH transmission being modulated by the second MCS.
10. The UE of claim 9 , wherein the first transmission is received via a broadcast control channel (BCCH).
11. The UE of claim 9 , wherein the second transmission is received via a multicast control channel (MCCH).
12. The UE of claim 9 , wherein the first subframe in which the MSI transmission is received corresponds to a subframe associated with an MCH subframe allocation.
