Positioning State Information Resource Allocation in 5G Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G wireless communication systems face challenges in efficiently reporting positioning state information, which is crucial for accurate location determination of mobile devices, due to limited resource allocation and potential interference with other channel state information.
Innovation Solution
Allocating dedicated resources for positioning state information, ensuring priority over channel state information, and preventing overlap with hybrid automatic repeat request (HARQ) to enhance the reporting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If positioning state information is multiplexed with channel state information on the same channel, then resource utilization is improved, but interference between information types occurs and reporting reliability deteriorates
Solution Approach 1:
The patent segments the uplink control information by creating separate logical channels for positioning state information (PSI) and channel state information (CSI). The PSI is mapped to dedicated physical resources (PUCCH or PUSCH) that are distinct from CSI resources, preventing interference while maintaining efficient resource utilization through structured resource allocation.
Solution Approach 2:
The patent introduces a new dimension of resource allocation by dedicating specific physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) resources exclusively for positioning state information. This separates PSI from CSI in the resource domain, eliminating interference while preserving resource efficiency through specialized allocation.
2Measurement precision
If positioning state information is transmitted with high priority, then location estimation accuracy is improved, but resource allocation complexity increases
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different types of uplink control information. Positioning state information is granted high priority with dedicated resources and protected mapping, while channel state information uses standard allocation. This localized quality enhancement ensures accurate location estimation without requiring high priority for all uplink transmissions.
Solution Approach 2:
The patent changes the resource allocation parameters specifically for positioning state information, including dedicated physical channel assignments, protected mapping rules, and priority-based scheduling. These parameter changes ensure high-priority transmission for PSI while maintaining standard parameters for other information types, avoiding unnecessary complexity in the overall system.
3Loss of information
If positioning state information is concatenated to channel state information, then signaling overhead is reduced, but information reliability deteriorates due to potential overlap with HARQ
Solution Approach 1:
The patent extracts positioning state information from the general uplink control information stream and places it in dedicated physical resources. By separating PSI from CSI and HARQ processes, the patent eliminates the risk of information overlap and loss while maintaining efficient signaling through specialized resource allocation and structured reporting formats.

AI summary
A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.
