Abstract

Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having processing circuitry arranged to determine to use an extended paging discontinuous reception (DRX) value to increase a paging cycle length above a value and select a first periodicity, based on the extended paging DRX value, at which the UE is to perform evaluation of a parameter of a network in which the UE is opera. The wireless communication device may have physical layer circuitry arranged to transmit a message to the network, indicating that the UE desires to perform evaluation of the parameter at the first periodicity. Other methods and apparatuses are also described.
