Claim 18:
19. Infrastructure equipment for use in a wireless communications network, the infrastructure equipment providing a wireless access interface within a system bandwidth, the system bandwidth comprising a plurality of bandwidth parts, the infrastructure equipment comprising:
a transmitter configured to transmit signals to a communications device using a plurality of activated bandwidth parts and using a plurality of activated beams;
a receiver configured to receive signals from the communications device using the plurality of activated bandwidth parts; and
a controller, configured to control the transmitter and the receiver so that the infrastructure equipment is operable:
to receive a beam failure indication indicating that an activated beam associated with a first activated bandwidth part satisfies beam failure criteria, the beam failure indication transmitted using communications resources associated with a second activated bandwidth part different in at least one aspect from the first activated bandwidth part, 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 activated bandwidth part.
