摘要： A method for correcting operation of the sleep oscillator (116) of a wireless communications device (100). Sleep oscillator frequency is estimated (412) so as to compensate for estimated temperature induced errors. In estimating temperature induced errors, errors (504) in sleep oscillator frequency are treated as being temperature induced errors (522), but probable multipath errors are bounded (410, 520) to predetermined sleep clock error maxima (602) corresponding to sleep duration over which the error occurred.

摘要： Methods and apparatus for searching a list of pilot signals. A method is provided for searching a list of pilot signals in a communication network. The method includes defining a prio list that indicates an order in which the list of pilot signals will be searched, obtaining a search duration, and determining an indicator that identifies a portion of the prio list that can be searched within the search duration. The method also includes performing a search of the portion of the prio list, and updating the list of pilot signals based on the results of the search.

摘要： Techniques for scanning other frequency channels for candidate base stations are described. In one scheme, the scanning of other frequency channels is performed based on the received signal quality (e.g., pilot Ec/Io) for an active base station that a wireless device is monitoring for user-specific and overhead messages. The scanning is bypassed if the active pilot Ec/Io exceeds a high threshold and performed if the active pilot Ec/Io is between the high threshold and a low threshold. In another scheme, the scanning of other frequency channels is performed at a rate that is a function of the active pilot Ec/Io. In yet another scheme, the scanning of other frequency channels is performed based on the active pilot Ec/Io and further using an adaptive timer. The timer is set to an initial value and thereafter adjusted by variable amounts determined by active pilot Ec/Io measurements.
