1. A user equipment device (UE) comprising: physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network; and processing circuitry configured to: receive system information via the network, wherein the system information indicates cell specific priority information and frequency carrier priority information; identify candidate cells that have a cell specific priority that is higher than a cell priority of the current serving cell, have a frequency priority that is higher than a frequency priority of a current serving frequency, and satisfy a cell suitability criterion; and determine a candidate cell from the identified candidate cells to replace the current serving cell for communicating with the network using the cell specific priority information and the frequency carrier priority information and disable selection of a candidate cell when the UE is identified as a high speed UE.
