Terminal Device Beam Information for Wireless Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inaccuracies in positioning terminal devices due to reliance on transmit beam information from base stations, which can lead to incorrect positioning results, especially in complex environments without a direct line of sight.
Innovation Solution
The method involves the terminal device transmitting its beam information to a network device, which can include a base station or a location calculation server, allowing for more accurate positioning by bypassing the limitations of transmit beam information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If positioning is based on transmit beam information of a base station, then the positioning method is simple, but the positioning accuracy deteriorates in complex environments without direct line of sight
Solution Approach 1:
Instead of using the base station's transmit beam information to determine terminal position, the patent inverts the approach by using the terminal device's own beam information (receive beam and transmit beam) for positioning. The terminal device determines its position based on the relationship between its receive beam direction and transmit beam direction, rather than relying on base station transmit beam information, thereby improving positioning accuracy in complex environments.
2Device complexity
If transmit beam information from base station is used for positioning, then the system implementation is straightforward, but the positioning reliability worsens when direct line of sight is blocked
Solution Approach 1:
The terminal device performs self-positioning by utilizing its own beam information (receive beam direction and transmit beam direction) rather than relying on base station transmit beam information. The terminal device independently determines its position based on the spatial relationship between its own beams, making the positioning more reliable in environments where direct line of sight between base station and terminal is blocked.
