摘要
A method and system for correcting timing errors due to thermal changes within a portable computing device are disclosed. The system and method may include calculating an estimate of frequency for a first clock compared to a second clock. The first clock may comprise a crystal oscillator while the second clock comprises a system clock. Next, a sleep state may be calculated for a hardware device, such as radio access technology (“RAT”) module, based on the estimate of frequency for the first clock. An error in the frequency of the first clock that may occur during the sleep state of the hardware device may be calculated. Subsequently, a magnitude of time that corresponds to an actual length of the sleep state relative to the second clock may be calculated so that an internal clock of the hardware devices may be synchronized with the second clock.
