1. A communications device for communicating via a wireless access interface, the communications device comprising:
transceiver circuitry and controller circuitry configured in combination
to receive signals using at least two of a plurality of bandwidth parts of the wireless access interface, each of the bandwidth parts of the plurality of bandwidth parts being smaller than and within a carrier bandwidth of the wireless access interface, wherein the at least two of the bandwidth parts of the plurality of bandwidth parts at least partially overlap in frequency resources of the carrier bandwidth and time resources of the wireless access interface, and one of the at least two bandwidth parts is nested within the other of the at least two of the bandwidth parts,
to receive the signals simultaneously via both of the at least two bandwidth parts of the plurality of bandwidth parts, and
to process each of the received bandwidth parts of the plurality of bandwidth parts separately to decode the signals received via each of the at least two bandwidth parts of the plurality of bandwidth parts separately,
wherein the other of the at least two bandwidth parts is always active in the time resources of the wireless access interface within a first time, and all other bandwidth parts of the plurality of bandwidth parts have at least one deactivation period in the time resources of the wireless access interface within the first time.
