摘要： Methods and apparatuses to determine a frequency adjustment in a mobile wireless device are disclosed. A method includes determining a coarse frequency error estimate and multiple fine frequency error estimates; selecting at least one candidate fine frequency error estimate having a frequency value closest to a corresponding frequency value for the coarse frequency error estimate; and determining a frequency adjustment based on a combination of the coarse frequency error estimate and the selected at least one candidate fine frequency error estimate. In an embodiment, the method further includes calculating a confidence metric for the coarse frequency error estimate; when the confidence metric exceeds a threshold value, determining the frequency adjustment based on the candidate fine frequency error estimate; otherwise, determining the frequency adjustment based on a fine frequency error estimate in the plurality of fine frequency error estimates closest to a most recent previous fine frequency error estimate.

摘要： A method to be performed by a wireless station having a wireless transceiver configured to establish a connection to a network, a processor and a non-transitory computer readable storage medium. The method includes receiving information during a first reception segment of a discontinuous reception cycle, wherein the discontinuous reception cycle includes the first reception segment and a first idle segment, performing a first measurement that begins during the first reception segment and performing a second measurement, wherein the second measurement begins prior to an end of the first measurement.

摘要： Methods and apparatuses to reduce a time to scan one or more frequency channel bands by a wireless communication device are disclosed. The methods include performing, at the wireless communication device, a power scan of a band of radio frequencies; determining a maximum power level for a frequency channel in the band of radio frequencies found by the power scan; comparing the maximum power level to a threshold power level; in an instance in which the maximum power level does not equal or exceed the threshold power level, attempting acquisition on a first number of frequency channels; and in an instance in which the maximum power equals or exceeds the threshold power level, attempting acquisition on a second number of frequency channels. The second number of frequency channels is greater than the first number of frequency channels.
