Wireless communications systems and methods related to communicating in a frequency band based on bandwidth parts are provided. A first wireless communication device communicates with a second wireless communication device, a first configuration indicating a plurality of bandwidth parts in a frequency band, the plurality of bandwidth parts based on an expected channel access pattern associated with a listen-before-talk (LBT) in the frequency band. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first bandwidth part of the plurality of bandwidth parts based on an LBT result.
