How Mobile Devices Automatically Manage Data Retransmission Errors
A method for mobile devices to efficiently track and fix data transmission errors by mathematically assigning ID tags to recurring data packets.
Original patent title: “USRE50045E1 - Apparatus and method for transmitting and receiving packets in a mobile communication system supporting hybrid automatic repeat request”
A method for mobile devices to efficiently track and fix data transmission errors by mathematically assigning ID tags to recurring data packets. Granted to Samsung Electronics Co Ltd in 2024 with 42 claims.
Key facts
Coverage
What does this patent actually cover?
When a phone receives data, some packets might arrive corrupted. This patent describes a system where the network and the phone agree on a mathematical formula to label these data packets using a HARQ process ID. By using the timing of the transmission and the interval of the resource allocation, the device can automatically calculate which ID belongs to which packet. This allows the device to correctly combine a failed initial transmission with a later retransmission to successfully decode the data.
The gap
What does this patent NOT cover?
- Does not cover data transmission methods that do not use semi-persistent resource allocation
- Does not cover error correction methods that rely solely on forward error correction without retransmission
- Does not cover the physical hardware design of the antennas or radio frequency transceivers
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
What made this novel
Instead of sending a unique ID for every single packet, the system uses a deterministic formula (HARQ process ID = s modulo n) that allows both the transmitter and receiver to calculate the ID independently based on time, saving precious bandwidth.
