摘要：
A wireless transmit/receive unit (WTRU) uses an oscillator providing accuracy for synchronized communications parameters in an active mode, and operates at reduced power during a discontinuous reception (DRX) mode. A real time clock (RTC) is used as the frequency standard during the reduced power operation, and a frequency adjustment is effected while the RTC is used as the frequency standard. By effecting the frequency adjustment, the RTC is able to be used as the frequency standard for substantial time periods, thereby reducing power consumption of the WTRU during the DRX mode.
