ITERATIVE RECEIVER WAKE-UP FOR LONG DRX PERIODS
First Claim
1. A method for communication, comprising:
- in a wireless communication terminal, estimating a wake-up time that is intended to not exceed an occurrence time of a periodic transmission that is addressed to the wireless communication terminal from a wireless network;
activating circuitry of the wireless communication terminal at the estimated wake-up time for receiving the periodic transmission; and
in response to finding, upon activating the circuitry, that the estimated wake-up time is too early to coincide with the periodic transmission, re-estimating a next wake-up time that is also intended to not exceed the occurrence time of the periodic transmission, and deactivating the circuitry until the re-estimated next wake-up time.

Abstract
A method for communication includes, in a wireless communication terminal, estimating a wake-up time that is intended to not exceed an occurrence time of a periodic transmission that is addressed to the wireless communication terminal from a wireless network. Circuitry of the wireless communication terminal is activated at the estimated wake-up time for receiving the periodic transmission. In response to finding, upon activating the circuitry, that the estimated wake-up time is too early to coincide with the periodic transmission, a next wake-up time, which is also intended to not exceed the occurrence time of the periodic transmission, is re-estimated, and the circuitry is deactivated until the re-estimated next wake-up time.

7. A communication apparatus, comprising:
-
a front end; and a processor, which is configured to estimate a wake-up time that is intended to not exceed an occurrence time of a periodic transmission that is addressed to the apparatus from a wireless network, to activate circuitry of the communication apparatus at the estimated wake-up time for receiving the periodic transmission, and, in response to finding, upon activating the circuitry, that the estimated wake-up time is too early to coincide with the periodic transmission from the wireless network, to re-estimate a next wake-up time that is also intended to not exceed the occurrence time of the periodic transmission, and to deactivate the circuitry until the re-estimated next wake-up time. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
