1. A method of activity control, said method comprising:
- during an active period of a first discontinuous reception (DRX) cycle, receiving a wireless signal;
based on the received wireless signal, calculating a value; and
based on the calculated value, calculating a starting time for the active period of a second DRX cycle subsequent to the first DRX cycle, wherein the calculated value indicates at least one among (A) a quality of the received wireless signal and (B) an error of at least one among time and frequency with respect to the received wireless signal.

Abstract
Embodiments include methods of activity control in which a time of initiation of an active period of a discontinuous reception (DRX) cycle is based on a value calculated with respect to a wireless signal received during an active period of a previous DRX cycle.

13. An apparatus for wireless communications, said apparatus comprising:
-
an oscillator configured to produce a frequency reference;
a radio-frequency (RF) receiver arranged to receive the frequency reference, wherein the RF receiver is configured to receive a wireless signal according to the frequency reference;
a sleep timer configured and arranged to activate said oscillator during the active periods of each of a plurality of discontinuous reception (DRX) cycles; and
a calculator configured to calculate, according to a value based on at least one among (A) a quality of a wireless signal received by said RF receiver during the active period of a first one of the plurality of DRX cycles and (B) an error of at least one among time and frequency with respect to a wireless signal received by said RF receiver during the active period of the first one of the plurality of DRX cycles, a starting time for the active period of a second one of the plurality of DRX cycles subsequent to the first one. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. An apparatus for wireless communications, said apparatus comprising:
-
means for receiving a wireless signal during an active period of a first discontinuous reception (DRX) cycle;
means for calculating a value based on the received wireless signal; and
means for calculating, based on the calculated value, a starting time for the active period of a second DRX cycle subsequent to the first DRX cycle, wherein the calculated value indicates at least one among (A) a quality of the received wireless signal and (B) an error of at least one among time and frequency with respect to the received wireless signal. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
