Methods, systems, and devices for wireless communication are described. A user equipment (UE) may adjust signaling in a slot configured for subband full-duplex (SBFD) communications based on receiving scheduling information indicating a signal. In a first option, a corresponding subband may be extended to include the signal. If there are remaining frequency resources, the remaining reverse-direction subband may be used for corresponding communications. In a second option, the remaining frequency resources of the reverse-direction subband may be used for same-direction communications as the signal. In a third option, the signal may be canceled, or a portion of the signal that is outside the corresponding subband may be canceled. In a fourth option, the signal may be treated as an error. In some examples, the options may be configured based on a type of the signal, or based on a priority level of the signal.
