Intel Patents Technology to Find Exact 5G Device Location Within Centimeters
GPS is good enough for directions, but Intel is working on a technique that could place a device within centimeters using the wave-phase of cellular signals, and this patent shows exactly how a phone would report those measurements.
How Intel's phase-based positioning actually works
Imagine you're trying to find your parked car in a crowded garage where GPS barely works. Your phone knows it's somewhere on level 3, but not whether it's in spot 3A or 3Z. That gap between "good enough" and "precise" is exactly what Intel's new patent targets.
Intel's approach works by having a phone measure the phase of a radio signal from a cell tower, not just whether the signal arrived, but where in its wave cycle it landed. Do that with two towers at once, compare the difference, and you can triangulate position far more tightly than conventional methods allow. The patent describes the specific data format a phone would use to report this combined measurement back to the network.
The clever part is that the phone sends both the new high-precision phase-difference reading and a standard legacy measurement in the same report, so existing network infrastructure doesn't have to be rebuilt to take advantage of it.
A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for carrier phase positioning and to cause the UE to decode a first DE PRS from a first transmission point (TP).
Translation: Special software tells a mobile device how to track its position using carrier phase signals from cellular towers.
Inside Intel's dual-tower phase difference measurement
The patent covers software instructions stored on a device (what Intel calls a UE, or User Equipment, basically any phone or modem chip) that configure it to perform carrier phase positioning.
Normally, a phone figures out its position using signal timing: how long did it take for a radio pulse to arrive? Carrier phase positioning is different. It looks at the phase of the radio wave itself (think of a wave's phase as which part of the ripple arrived, the crest, the trough, or somewhere in between). Because phase can be measured much more finely than a pulse's arrival time, it can yield centimeter-level accuracy instead of meter-level.
The specific steps the patent describes:
- Decode a Downlink Positioning Reference Signal (DE PRS) from a first cell tower, this is a specially designed radio signal used only for positioning, not data.
- Compute a DE RSCP (a phase measurement) from that first signal.
- Repeat the process with a second tower's DE PRS.
- Calculate a DE RSCPD, the difference between the two phase measurements. That differential cancels out many error sources and sharpens the position fix.
- Bundle this new high-precision differential alongside a standard legacy measurement in a single report sent back to the network.
The dual-report approach is key: it lets a network that understands carrier phase use the new data, while networks that don't can still fall back on the familiar measurement without any special handling.
What this means for 5G chip location accuracy
Precise indoor and urban positioning is one of the harder unsolved problems in cellular networking. Emergency services need to know which floor of a building a 911 caller is on. Autonomous vehicles need lane-level accuracy in GPS-poor tunnels. Augmented reality glasses need to know exactly where a user is standing, not just the block they're on. Carrier phase techniques are a leading candidate to close that gap inside the 5G standard.
For Intel specifically, this sits squarely in its modem and baseband chip business. A modem that correctly implements this measurement format is more attractive to phone makers who need to comply with 3GPP positioning accuracy requirements. Engineers working on 5G chipsets or positioning software are the ones who will feel this most directly, it is a relatively narrow but technically meaningful filing. Positioning is one of the more active corners of new Big Tech patents as chipmakers race to meet the centimeter-accuracy targets written into 5G standards.
Phone signals struggle to pinpoint your location inside buildings or between tall city blocks. That failure has real consequences: a 911 dispatcher cannot find you, or a delivery robot gets lost. A more precise measurement method, already trusted in GPS systems, can fix this. Intel's patent locks down the specific way a phone would need to report that measurement to a 5G network.
Whether any of this works in practice comes down to one thing. Standards bodies must write Intel's exact reporting format into the rules that phone makers actually follow.
