Claim 0:
1. A communications system for use in a wireless communications network, the wireless communications network comprising an infrastructure equipment providing a wireless access interface within a system bandwidth, the system bandwidth comprising a plurality of bandwidth parts, the communications system comprising:
a transmitter configured to transmit signals using a plurality of activated bandwidth parts,
a receiver configured to receive signals using the plurality of activated bandwidth parts, the received signals being signals transmitted using a plurality of activated beams, and
a controller configured to control the transmitter and the receiver so that the communications system is operable:
to determine that an activated beam associated with a first bandwidth part satisfies beam failure criteria;
to select from the plurality of activated bandwidth parts a second bandwidth part; and
to transmit using communications resources associated with the selected second bandwidth part a beam failure indication indicating that the activated beam associated with the first bandwidth part satisfies the beam failure criteria, wherein

one of the plurality of activated bandwidth parts is a primary bandwidth part which is in an activated state while a plurality of other bandwidth parts, each as a secondary bandwidth part, is in the activated state, and
the beam failure indication comprises an indication of an identity of the first bandwidth part.
