AI Technical Summary
In high-density user equipment environments, existing positioning methods face limitations in message passing and bandwidth, making it difficult to effectively utilize 5G NR beamforming for passive positioning, especially in dense UE environments where scaling is challenging.
Using analog beamforming technology, the location is determined by exchanging positioning reference signals between the first and second wireless nodes and combining the timing difference measurement of the user equipment to calculate the time difference of arrival.
It enables passive positioning in high-density environments without requiring UE responses, avoids bandwidth limitations, can be effectively scaled to a large number of devices, and improves positioning efficiency and accuracy.
