Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning methods in new generations of wireless communication networks, such as 5G, face challenges in efficiently managing position information for a large number of wireless devices, leading to increased overhead and reduced scalability, especially when dealing with devices having reduced positioning capabilities.
Innovation Solution
Implementing a method where a positioning representative wireless device within a group communicates directly with other group members to estimate and share position information, reducing the need for network-assisted positioning for all devices and enhancing spectrum efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional network-assisted positioning methods are used for all wireless devices, then positioning accuracy is maintained, but network overhead increases and scalability decreases
Solution Approach 1:
The patent segments the positioning function by dividing wireless devices into two categories: capable devices that perform autonomous positioning and represent themselves to the network, and incapable devices that rely on capable devices to represent their positions. This segmentation reduces network overhead by eliminating redundant positioning requests for incapable devices while maintaining positioning accuracy through the representative mechanism.
Solution Approach 2:
Capable wireless devices perform autonomous positioning operations without requiring network assistance, determining their own positions using available positioning methods and technologies. These self-positioned devices then represent incapable devices to the network, enabling the incapable devices to benefit from positioning capabilities they lack while reducing overall network positioning overhead.
2Reliability
If network-assisted positioning is provided for all devices, then positioning capability is ensured, but spectrum efficiency decreases
Solution Approach 1:
The patent merges the positioning representation function by having capable devices represent multiple incapable devices to the network. Instead of each incapable device independently requesting network positioning assistance, a single capable device can represent multiple incapable devices, consolidating positioning signaling and improving spectrum efficiency while ensuring all devices maintain positioning capability.
3Measurement precision
If positioning support is provided for each device individually, then positioning accuracy is maintained, but device complexity increases
Solution Approach 1:
Capable wireless devices act as intermediaries between incapable devices and the network positioning infrastructure. The capable device receives positioning information from the network and shares it with incapable devices, while also representing the positions of incapable devices to the network. This intermediary role reduces positioning processing complexity for incapable devices while maintaining positioning accuracy through the capable device's representation.

Methods and nodes (110; 115; 116; 117; 120; 121; 130; 140) for managing position information associated with a group of wireless devices (120-121) configured to be served in a wireless communication network (100). It is obtained (201; 301-303; 501; 501a-b) information indicating a first wireless device (120) as member and positioning representative of the group and at least one other, second, wireless device (121) as further member of the group. Said at least one second wireless device (121) being able to communicate wirelessly and directly with the first wireless device (120) over a direct communication link (125). A position of said at least one second wireless device (121) is estimated based on communication of positioning supporting information over said direct communication link (125).
