1. A method of receiving data at a communications device from a wireless communications network, the method comprising
receiving, by a receiver of the communications device, downlink data during an initial access phase of a communications session of the communications device from a wireless access interface provided by the wireless communications network, and
receiving, by the receiver of the communications device, other downlink data during a connected phase of the communications session of the communications device transmitted to the communications device via the wireless access interface, the wireless access interface providing communications resources comprising a predetermined number of OFDM symbols in each of a plurality of time slots, the OFDM symbols in the initial access phase having a greater number of sub-carriers available to carry the downlink data within greater frequency domain physical resources than the OFDM symbols in the connected phase in which the OFDM symbols have a smaller number of sub-carriers available to carry the other downlink data within smaller frequency domain physical resources, wherein the receiving the downlink data during the initial access phase, comprises receiving the downlink data from
a reduced number of OFDM symbols per time slot or over a plurality of consecutive time slots and an increased number of the available sub-carriers per OFDM symbol compared to the receiving of the other downlink data during the connected phase, or
a reduced number of the available sub-carriers per OFDM symbol of the initial access phase and an increased or the same number of OFDM symbols per time slot or over a plurality of consecutive time slots compared to the receiving of the other downlink data during the connected phase, and the receiving, by the receiver of the communications device, the downlink data during the initial access phase includes
processing the downlink data with a maximum rate of processing the downlink data which is less than or equal to a maximum rate of processing the other downlink data received during the connected phase.
