Claim 12:
13. A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by one or more processors, causes the one or more processors to perform a method for a communications system 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 method comprising:
transmitting signals using a plurality of activated bandwidth parts,
receiving signals using the plurality of activated bandwidth parts, the received signals being signals transmitted using a plurality of activated beams,
determining that an activated beam of the plurality of activated beams associated with a first bandwidth part of the plurality of activated bandwidth parts satisfies beam failure criteria,
responsive to said determining that the activated beam associated with the first bandwidth part satisfies the beam failure criteria, selecting from the plurality of activated bandwidth parts a second bandwidth part that is active at a first same time as said first bandwidth part, and
transmitting 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.
