Abstract
A device-specific synchronization signal (DS-SS) is transmitted by a base station within a data channel transmission to a mobile device before a paging time window for the mobile device. After a sleep state, the mobile device attempts to acquire the DS-SS without decoding a downlink control channel to obtain signal transmission information related to transmission of the page message from a base station. In addition to providing timing information for resynchronization, the DS-SS indicates the existence of a page message for the mobile device within the data channel. The mobile device returns to the sleep state in response to not detecting a DS-SS that indicates a page message. Prior to entering a sleep state, the mobile device receives transmission format information indicative of a transmission format of the DS-SS.
