摘要：A system and method for paging wireless mobile devices lectively varies the
effective modulation order of a paging channel to achieve improved coverage in a wireless wide area network (WWAN) cell. In one embodiment, the paging channel modulation order is lected bad on a measured signal strength and/or common channel error rate. The lected modulation order is directly related to the quality of the channel environment. In another embodiment, a page message is gregated into ba and extended components that are layer modulated. With layered modulation, wireless mobile devices in good coverage regions can successfully demodulate both the ba and extended components to recover the entire page message. Wireless mobile devices in poor coverage regions can successfully demodulate the ba component of the page message, and then request that the extended component of the page message be re-broadcast as a ba component to thereby recover the entire page message.dothelaundry
