Abstract
Embodiments of the present invention include devices, systems and methods for optimized camping on a cell. One method can include beginning a power scan of a range of radio-frequency channel numbers as part of an acquisition. Power can be measured for a first set of radio-frequency channel numbers at a time using adjacent channel interference detection. An average power can be computed for each radio-frequency channel number once the range has been scanned a predetermined number of times. Other aspects, embodiments and features are also claimed and described.
Claims29
A method for wireless communication by a wireless communication device, comprising:
- beginning a power scan of a range of radio-frequency channel numbers as part of an acquisition;
- measuring power of a first set of radio-frequency channel numbers at a time using adjacent channel interference detection, wherein no absolute radio-frequency channel numbers are skipped between each adjacent channel interference scan;
- and computing an average power for each radio-frequency channel number once the range has been scanned a predetermined number of times;
- wherein measurements from complex bandpass filters are used to calculate the power of neighboring radio-frequency channel numbers.
An apparatus for wireless communication, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- begin a power scan of a range of radio-frequency channel numbers as part of an acquisition;
- measure power of a first set of radio-frequency channel numbers at a time using adjacent channel interference detection, wherein no absolute radio-frequency channel numbers are skipped between each adjacent channel interference scan;
- and
- compute an average power for each radio-frequency channel number once the range has been scanned a predetermined number of times;
- wherein measurements from complex bandpass filters are used to calculate the power of neighboring radio-frequency channel numbers.
A wireless device, comprising:
- means for beginning a power scan of a range of radio-frequency channel numbers as part of an acquisition;
- means for measuring power of a first set of radio-frequency channel numbers at a time using adjacent channel interference detection, wherein no absolute radio-frequency channel numbers are skipped between each adjacent channel interference scan;
- and
