User equipment (a mobile device) obtains measurement reports for available new radio frequency bands. The mobile device can prioritize the reporting of the measurement data so as to indicate to the network which candidate PSCell that the user equipment prefers to have selected. The network can bias selection of one candidate PSCell over others by providing different time-to-trigger periods for different available frequency bands. A mobile device can prioritize PSCell selection based on current conditions, such as based on application program needs, so as to use a PSCell with bandwidth that is appropriate for a current application program in use. The mobile device and network can collaborate to select a PSCell based on other conditions such as remaining battery capacity of the device and/or thermal conditions. ## Claims ### Claim 1 A mobile device, comprising: a processor;
