Apple patents phone method to wake up only when needed to save battery
This patent describes a way for a phone to decide when to turn on its radio to check for new data. It uses a specific signal and a setting to ensure the device only wakes up from sleep mode when necessary, rather than checking constantly.
In the filing’s own words
A user equipment (UE) having enhanced configured grant transmission is provided. The UE operates by determining whether a wake-up signal (WUS) indicator is received. The UE also determines whether a wake-up trigger condition is met, and based on a determination that the trigger condition is met, it determines whether the UE is configured with a power-save wake up (ps-WakeUp) parameter. Based on a determination that the UE is configured with the ps-WakeUp parameter, the UE determines whether the ps-WakeUp parameter is set to false. Further, based on a determination that the ps-WakeUp parameter is set to false, and based on a determination that the WUS indicator is not received, the UE transitions from a sleep state to an active state during a next discontinuous reception (DRX) on-duration period.
What exactly they claim (claim 1)
1. A user equipment (UE), comprising: a transceiver configured to enable wireless communication; and a processor communicatively coupled to the transceiver and configured to: determine whether a wake up signal (WUS) indicator is received; determine whether a wake-up trigger condition is met; based on a determination that the wake-up trigger condition is met, determine whether the UE is configured with a power-save wake up (ps-WakeUp) parameter; based on a determination that the UE is configured with the ps-WakeUp parameter, determine whether the ps-WakeUp parameter is set to false; and based on a determination that the ps-WakeUp parameter is set to false, and based on a determination that the WUS indicator is not received, configure the UE to transition from a sleep state to an active state during a next discontinuous reception (DRX) on-duration period.
