1. A method of a user equipment (UE), comprising:
identifying a plurality of sub-bands (SBs) of a serving cell of the UE using SB configuration information received from a network, wherein adjacent SBs of the plurality of SBs are separated by one or more guard bands (GBs);
sending, to the network, a UE capability report indicating that the UE is capable of basing a determination of whether any of the one or more GBs are valid for resource allocation on dynamic SB directional information in a downlink control information (DCI);
determining communication directions for the plurality of SBs during a first slot using the dynamic SB directional information received from the network in the DCI; and
communicating with the network on the serving cell using resources of the plurality of SBs during the first slot according to the communication directions for the plurality of SBs during the first slot.
