1. A method comprising:
receiving a high-layer signaling of a set of UE-specific downlink (DL) or uplink (UL) bandwidth parts (BWPs) for a serving cell from a base station by a user equipment (UE) over an active DL BWP in a primary cell, wherein a BWP configuration of each UE-specific DL or UL BWP in the higher-layer signaling includes at least a set of radio resource clusters;
determining frequency locations of each set of radio resource clusters of a UE-specific DL or UL BWP based on a set of contiguous physical resource blocks (PRBs) and a same numerology of the UE-specific DL or UL BWP, wherein guard bands are reserved at two sides of and within each radio resource cluster in each of the UE-specific DL or UL BWPs in frequency domain; and
receiving a DL or UL BWP switch signal over the active DL BWP to switch an active DL or UL BWP from one DL or UL BWP to another DL or UL BWP for the serving cell, respectively.
