Abstract: Example embodiments relate to wideband communications based on availability assessment. A method for communication comprises performing availability assessment on a set of configured frequency subbands to obtain an availability result, the availability result indicating that at least one of the set of configured frequency subbands is available for a period of time for transmission of intended information and transmitting supplementary information that has been prepared using the at least one frequency subband during a first portion of time within the period of time. The method also comprises preparing the intended information based on the availability result and transmitting the prepared intended information using the at least one frequency subband during a second portion of time following the first portion of time within the period of time. As such, the processing of the intended information can be adapted depending on the dynamic available subband(s) indicated by the availability result.
