Position Determination of a Wireless Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18245732 titled 'Position Determination of a Wireless Device
Simplified Explanation
The patent application describes a method for determining the position of a wireless device using angle-of-arrival values from multiple antenna arrays.
- The method estimates angle-of-arrival values for each antenna array by measuring phase differences between antenna elements.
- Each antenna array is arranged along a line, and at least two of the lines are not in the same position.
- The position of the wireless device is determined by combining the angle-of-arrival values from the multiple antenna arrays.
Original Abstract Submitted
There is provided mechanisms for position determination of a wireless device. A method is performed by a network node. The method comprises estimating a respective angle-of-arrival value for each of at least three ID antenna arrays from measured phase differences between antenna elements per ID antenna array for a signal communicated between the wireless device and the at least three ID antenna arrays. The antenna elements of each ID antenna array are arranged along a respective line. At least two of the lines are non-coincident with respect to each other. The method comprises determining the position of the wireless device by combining the angle-of-arrival values from the at least three ID antenna arrays.
