Abstract: An infrastructure equipment as part of a mobile communications network receives an indication that data is to be transmitted to one of communications devices. In response the infrastructure equipment transmits a first paging message to the communications device to indicate the communications device is to receive the data via a wireless access interface. If a response to the transmitted first paging message is not received within a predetermined time, then if the infrastructure equipment can use a power boosting mode, to transmit the first paging message with a boosted power, or if the infrastructure equipment cannot use a power boosted mode for transmitting, to transmit a second paging message to one or more communications apparatus which can operate as a relay node for the communications device. The second paging message identifies the relay node and the communications device for which the infrastructure equipment is to transmit the data.
