User equipment and method for handling switching time period of downlink-uplink switching for half duplex-frequency division duplex operation

A user equipment (UE) for handling a switching time period of downlink (DL)-uplink (UL) switching for half duplex-frequency division duplex (HD-FDD) operation, the UE comprising:

• one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor is configured to execute the computer-executable instructions to:
• receive a first configuration for a first active bandwidth part (BWP) with a first sub-carrier spacing (SCS), the first active BWP being one of an active UL BWP and an active DL BWP;
• receive a second configuration for a second active BWP with a second SCS, the second active BWP being another one of the active UL BWP and the active DL BWP;
• receive a third configuration for the switching time period, the switching time period having a unit of symbol;
• perform communication with a Base Station (BS) on the first active BWP with the first SCS;
• and
• perform, after the switching time period, communication with the BS on the second active BWP with the second SCS.
