Bandwidth part (bwp) switching

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a base station (BS) operating in a 5G network, the instructions to configure the one or more processors for active bandwidth part (BWP) switching during New Radio (NR) communications and to cause the BS to:

• encode radio resource control (RRC) signaling configuring a plurality of BWPs for a user equipment (UE), the RRC signaling further including an indicator for an initial BWP of the plurality of BWPs for initial use by the UE as an active BWP;
• and
• encode downlink control information (DCI) for transmission to the UE on a physical downlink control channel (PDCCH), the DCI including a BWP indicator for switching the active BWP from the initial BWP to another BWP of the plurality of BWPs;
• wherein the RRC signaling and the DCI further cause reconfiguration of radio frequency (RF) and baseband parameters for switching the active BWP from the initial BWP to the another BWP, wherein reconfiguring the RF and baseband parameters cause an interruption of one or more slots of a serving cell of the UE, and wherein a starting time of the interruption is within a time duration of a BWP switching delay supported by the UE.

• decode downlink control information (DCI) received on a physical downlink control channel (PDCCH), the DCI including a BWP indicator for switching the active BWP from the initial BWP to another BWP of the plurality of BWPs;
• and
