1. A method in a User Equipment (UE) for control of Bandwidth Part (BWP) switching, wherein the UE communicates with a network device for transfer of data utilizing the BWP switching, the method comprising:
establishing a wireless communication link between the UE and the network device for the transfer of data;
determining that the UE has an active configured grant in a non-default BWP by determining that there is a Physical Uplink Shared Channel (PUSCH) or Physical Downlink Shared Channel (PDSCH) transmission, wherein the configured grant is an uplink grant to the UE or a downlink assignment from the network device, wherein a BWP inactivity timer is set to be active for a set duration to maintain the non-default BWP active, and wherein at an expiration of the BWP inactivity timer, the BWP switching is set to switch from the non-default BWP to a default BWP;
receiving from a network device, via Radio Resource Control (RRC) signaling, a message to restart the BWP inactivity timer each time when there is a PUSCH or PDSCH transmission in accordance with the configuration grant; and
refraining from switching from the non-default BWP to the default BWP during a life duration of the configured grant while the configured grant remains active by restarting the BWP inactivity timer in response to the message.
