Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a positioning processing method, a positioning reference signal sending method, an apparatus and a device. Background Art

[0002] Positioning research has raised the need for high-precision positioning. However, in scenarios with complex multipath and a large number of non-line-of-sight (NLOS) conditions (such as in densely populated smart factories), time- and angle-based positioning solutions are significantly affected by multipath and NLOS, leading to a significant decline in positioning accuracy. Positioning methods based on machine learning or fingerprinting can effectively address these issues and achieve higher accuracy. However, due to the large random variations in the channel impulse responses of closely located terminals in NLOS scenarios, the performance of trained positioning is degraded. Leveraging certain channel characteristics, such as the first path phase difference and additional path phase difference between different antennas, for training can effectively improve positioning accuracy.

[0003] Currently, in uplink angle of arrival (UL-AoA) positioning, it is agreed to report the UL-AoA measurement values ​​of M>1 first paths; in downlink angle of departure (DL-AoD) positioning, it is agreed to study the measurement and reporting of several first path related information, such as the reference signal receiving power (RSRP) of the first path, departure angle, arrival time, channel impulse response (CIR) phase, etc.
