Abstract
A method for clock calibration is provided. The method comprises receiving discontinuous reception period (DRX period) information from a base station, computing a calibration duration according to the discontinuous reception period and a clock error tolerance of a first clock, and when receiving paging information that informs of possible sent transmissions, calibrating the first clock with a second clock for a period of the calibration duration.

A method for clock calibration, comprising:
- receiving discontinuous reception period (DRX period) information from a base station;
- computing a calibration duration according to the discontinuous reception period and a clock error tolerance of a first clock;
- upon receiving paging information that informs of possible sent transmissions, calibrating the first clock with a second clock for a period of the calibration duration;
- performing the calibration for a predetermined number of times, and
- wherein the computation of the calibration duration comprises computing the
- calibration duration according to the discontinuous reception period, the clock error tolerance of a first clock, and the predetermined number of times of calibration, and a sum of all calibration durations is less than a predetermined duration limit.
A wireless telecommunication apparatus with a first clock and a second clock, and the second clock has a faster clock speed than the first clock, the wireless telecommunication apparatus comprising:
- a receiver, receiving discontinuous reception period (DRX period) information from a base station;
- a decision unit, computing a calibration duration according to the discontinuous reception period and a clock error tolerance of the first clock;
- and
- a calibration unit, upon receiving paging information that informs of possible sent transmissions, calibrating the first clock with the second clock for a period of the calibration duration,
- wherein the calibration unit performs the calibration for a predetermined number of times, and the computation of the calibration duration comprises computing the calibration duration according to the discontinuous reception period, the clock error tolerance of a first clock, and the predetermined number of times of calibration, and a sum of all calibration durations is less than a predetermined duration limit.
