Abstract
A communications device for use in a wireless communications network providing a wireless access interface within a system bandwidth, the system bandwidth comprising a plurality of bandwidth parts, the communications device 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 device 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.
