Apple patents method to manage traffic for direct device-to-device location signals
Apple has filed a patent application for a way to manage data traffic when devices communicate directly with each other to determine their location. The system uses congestion control to check how busy the channel is and reserves specific resources to ensure the location signal gets through without interference.
In the filing’s own words
Techniques, described herein, include solutions for allocation sidelink positioning reference signals (SL-PRS). In some aspects, various aspects of SL-PRS congestion control, reserving resources for another UE, and inter-UE coordination of using assisting information from an assist UE for SL-PRS resource selection is illustrated for improving SL-PRS communication.
What exactly they claim (claim 1)
1. A baseband processor for a first User Equipment (UE), the baseband processor configured to execute instructions stored in one or more memories and perform operations comprising: decoding congestion control information for a sidelink positioning reference signal (SL-PRS) communication to a second UE; determine resources for the SL-PRS communication; performing congestion handling based on the congestion control information; and after performing the congestion handling, performing the SL-PRS communication on the resources.
