Dynamic uplink and downlink operating switching in wireless communication systems

A user equipment (UE), comprising:

• a memory device, and
• a processor configured to execute instructions stored on the memory device, wherein the instructions cause the processor to:
• configure the UE with a first UL subband configuration for communicating with an external device, wherein the first UL subband configuration designates a first set of one or more resource blocks (RBs) inside of a carrier for the UE to perform UL transmission,
• receive a downlink (DL) signal indication providing information indicating an overriding duration, and
• override the first UL subband configuration with a second subband configuration based on the DL signal indication, wherein the second subband configuration designates a first communication configuration of the first set of one or more RBs inside of the subband and a second communication configuration of a second of one or more RBs outside of the subband.
