A method of receiving data by a communications device (104, 260, 270) in a wireless communications network (100, 200), the method comprising receiving a downlink control message transmitted in first downlink communications resources of a wireless access interface provided by the wireless communications network, the downlink control message providing an indication of second downlink communications resources from which the communications device can receive downlink data, and receiving the downlink data from the second downlink communications resources, wherein the communications device (104, 260, 270) is configured to operate in a first reception mode in which a receiver of the communications device (104, 260, 270) is configured to receive the downlink data transmitted according to a first format via the second downlink communications resources, or to operate in a second reception mode in which the receiver of the communications device (104, 260, 270) is configured to receive the downlink data transmitted according to a second format via the second downlink communications resources, the method comprising receiving a mode switching control message, the mode switching control message indicating that a mode of operation of the communications device (104, 260, 270) is to be changed from one of the first reception mode and the second reception mode to the other of the first reception mode and the second reception mode until another mode switching control message is received, and transmitting one or more signals to confirm a current mode of operation, wherein the transmitting the one or more signals to confirm the current mode of operation comprises: determining uplink communications resources allocated for a transmission of an acknowledgement of the mode switching control message, determining that the acknowledgement is to be transmitted in response to receiving the mode switching control message, and transmitting the acknowledgement using the allocated uplink communications resources. receiving a downlink control message transmitted in first downlink communications resources of a wireless access interface provided by the wireless communications network, the downlink control message providing an indication of second downlink communications resources from which the communications device can receive downlink data, and receiving the downlink data from the second downlink communications resources, wherein the communications device (104, 260, 270) is configured to operate in a first reception mode in which a receiver of the communications device (104, 260, 270) is configured to receive the downlink data transmitted according to a first format via the second downlink communications resources, or to operate in a second reception mode in which the receiver of the communications device (104, 260, 270) is configured to receive the downlink data transmitted according to a second format via the second downlink communications resources, the method comprising receiving a mode switching control message, the mode switching control message indicating that a mode of operation of the communications device (104, 260, 270) is to be changed from one of the first reception mode and the second reception mode to the other of the first reception mode and the second reception mode until another mode switching control message is received, and transmitting one or more signals to confirm a current mode of operation, wherein the transmitting the one or more signals to confirm the current mode of operation comprises: determining uplink communications resources allocated for a transmission of an acknowledgement of the mode switching control message, determining that the acknowledgement is to be transmitted in response to receiving the mode switching control message, and transmitting the acknowledgement using the allocated uplink communications resources. determining uplink communications resources allocated for a transmission of an acknowledgement of the mode switching control message, determining that the acknowledgement is to be transmitted in response to receiving the mode switching control message, and transmitting the acknowledgement using the allocated uplink communications resources.
