A communications device transmits/receives data to/from infrastructure equipment forming part of a communications network. The communications device includes a controller and a transceiver configured to transmit and/or receive signals representing the data to/from the infrastructure equipment. The transceiver is configured to, under control of the controller, transmit a request for services message to the infrastructure equipment, and receive a response message to the request for services message from the infrastructure equipment. The request for services message includes a delay period, and the controller is configured after transmission of the request for services message to configure the transceiver to enter a reduced power state in which an amount of power consumed by the transceiver is reduced for the delay period. The controller is also configured, after the delay period has expired, to configure the transceiver to exit the reduced power state to receive the response message from the infrastructure equipment.
