Abstract
A mobile station (102) has electrical circuitry (301) that operates to reduce power consumption. A synthesizer (318) is tuned so that a receiver (314) receives a home radio frequency (RF) signal during a receive slot (504) of a PCH subframe (209). A controller (310) detects if an upcoming subframe has an uplink requirement and if data from the home RF signal indicates that an idle condition exists. If the upcoming subframe does not have an uplink requirement, synthesizer (318) is tuned during a long idle slot (506) of PCH subframe (209) to measure signal strengths of two peripheral RF signals. If the idle condition does exist, electrical circuitry (301) is placed into a low power mode throughout a transmit slot (508), a receive slot (512), a long idle slot (514), and a transmit slot (516).
