Apple patents method for adjusting phone power saving based on data type

Apple has been granted a patent for a method that helps mobile devices manage their power consumption more efficiently during data transmission. The system determines how long the phone's radio should stay active by looking at the specific type of data being sent, allowing it to switch to a low-power state faster when appropriate.

Why it mattersThis is a routine improvement to cellular network protocols that helps extend battery life by fine-tuning how quickly phones stop listening for new data instructions.

In the filing’s own words

A method and apparatus are provided for, in aspects, receiving, at a User Equipment (UE), a configuration relating to a logical channel (LCH) from a Base Station (BS); receiving, at the UE, an uplink grant for an uplink data; identifying a subset of the LCH mappable to the uplink grant based on the at least a part of the configuration; determining, at the UE, a connected-mode discontinuous reception (C-DRX) setting to be applied for an uplink transmission associated with the uplink grant based on the identified subset of the LCH; and controlling a quiescent state of the UE based on the C-DRX setting, wherein, in aspects, mappable may refer to allowed to be mapped or actually mapped. When LCHs of the subset are associated with different C-DRX settings, rule-based C-DRX selection can be used.

What exactly they claim (claim 1)

1. An apparatus for a User Equipment (UE), comprising: a memory; and a processor coupled to the memory and operable to, when executing instructions stored in the memory, cause the UE to: receive a logical channel (LCH) configuration from a base station; receive an uplink grant for an uplink transmission; identify a subset of LCHs mappable to the uplink grant based on the LCH configuration; determine a connected-mode discontinuous reception (C-DRX) setting to be applied for the uplink transmission associated with the uplink grant based on the subset of the LCHs, wherein the determination includes selecting a C-DRX setting for a physical uplink shared channel (PUSCH) based on a ranking rule when a plurality of C-DRX settings are associated correspondingly with the subset of LCHs; and change, at the UE, an activity level for physical downlink control channel (PDCCH) monitoring according to a timing based on the C-DRX setting.
