A mobile communications network for communicating broadcast data to a plurality of mobile communications devices by transmitting the broadcast data via a wireless access interface, the mobile communications network including a plurality of base stations disposed throughout the network and arranged in operation to transmit signals to mobile communications devices attached to the base stations, and one or more relay nodes. One of the relay nodes is arranged in operation to receive a first signal representing the broadcast data transmitted by one or more of the base stations and to retransmit the broadcast data as a second signal, the first signal being broadcast for reception by a first mobile communications device and the relay node and the second signal being broadcast for reception by a second mobile communications device. The first signal is transmitted on a first channel of the wireless access interface, and the second signal is transmitted in a second channel of the wireless access interface,and one or more of the base stations is arranged to communicate data to a third mobile communications device in the second channel contemporaneously with the transmission of the broadcast data on the second channel by the relay node. Accordingly a relay node layer can be provided to a mobile radio network which improves an efficiency of use of the available communications resources. |
