Various techniques for improving a wireless communication device are described. The techniques may include reducing power in a wireless communication device for a first sleep period and then increasing power in the wireless communication device for an intermediate wake period after the first sleep period to estimate an error of the sleep clock. The method may further include reducing power in thewireless communication device for a second sleep period after the intermediate wake period. The intermediate wake mode implemented during the intermediate period can be used to estimate the error of the sleep clock without performing one or more tasks associated with an awake mode, such as demodulation. The techniques may facilitate the effective use of low frequency low power clocks for sleep mode, even when relatively large slot cycles are defined within a slotted paging system.
