Abstract
A method performed by a network node for transmitting enhanced Multimedia Broadcast Multicast Services, eMBMS, control information to wireless devices in a wireless telecommunications network is provided. The eMBMS control information comprises MBMS Single Frequency Network, MBSFN, area configuration information and MCH Scheduling Information, MSI, for a Multicast CHannel, MCH. The MBSFN area configuration information and the MSI indicate Multicast Traffic Channels, MTCHs, for the eMBMS. The network node configures the indication of the MTCHs in the MBSFN area configuration information and in the MSI based on an order of logical channel identities of the MTCHs that is set in the network node. Then, the network node transmits the MBSFN area configuration information and MSI to the wireless devices in the wireless telecommunications network.A network node and a system are also provided.
