Samsung patents phone feature to save battery by skipping data re-checks

Patent drawing
Patent drawing from the official filing.

Samsung describes a method for phones to send data without waiting for a standard confirmation loop called Hybrid Automatic Repeat Request (HARQ). By identifying data that does not need retransmission, the device stops listening for network signals and enters a low-power sleep mode sooner.

Why it mattersThis could help smartphones last longer between charges by reducing the time they spend actively listening to the network for data confirmations.

In the filing’s own words

An electronic device may include: a memory storing instructions; and at least one processor, wherein the instructions, when executed by at least one processor, cause the electronic device to: identify, based on feedback information corresponding to one or more hybrid automatic repeat request (HARQ) process IDs, a first data block determined not to perform HARQ retransmission (HARQ-less) among one or more data blocks; based on at least one block being identified as the first data block, transmit, to a base station using the first data block, data classified as not performing retransmission; stop monitoring a physical downlink control channel (PDCCH) being executed for retransmitting the HARQ; and switch the electronic device into a sleep state.

What exactly they claim (claim 1)

1. An electronic device, comprising: memory storing instructions; and at least one processor comprising processing circuitry, wherein the instructions, when executed by at least one processor, individually or in any combination, cause the electronic device to: identify, based on feedback information corresponding to one or more hybrid automatic repeat request (HARQ) process IDs, a first data block determined not to perform HARQ retransmission (HARQ-less) among one or more data blocks, transmit, to a base station using the first data block, data classified as not performing retransmission based on at least one block being identified as the first data block, and stop monitoring a physical downlink control channel (PDCCH) being executed for retransmitting the HARQ and switch the electronic device into a sleep state.
