1. A method for a user equipment (UE) to communicate with a new radio (NR) wireless network in a standalone (SA) deployment, the method comprising:
camping the UE on a first cell of the NR wireless network in the SA deployment, wherein the first cell is a serving cell;
determining, at the UE, that a first bandwidth (BW) of the first cell is greater than or equal to a threshold BW value;
in response to the first BW of the first cell being greater than or equal to the threshold BW value and the UE not being configured by the NR wireless network for bandwidth part switching (BWPS), and based on one or more applications running on the UE, determining, at the UE, whether a second cell is available that is intraband with and has a same priority as the first cell and that has a second BW that is less than the threshold BW value, wherein the second cell is of the NR wireless network in the SA deployment;
when the second cell is not available, searching for a third cell with a next lower priority than the first cell, that has a third BW that is less than the threshold BW value, and that has a received power measured at the UE greater than or equal to a reference signal received power (RSRP) threshold value, wherein the third cell is of the NR wireless network in the SA deployment; and
when the second cell is available, camping the UE on the second cell.
