Non-Contiguous Positioning Reference Signal Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operations of base stations and terminals corresponding to different duplex methods in NR release 18 and 6G are unclear, particularly in terms of frequency resource allocation and support by base stations and terminals.
Innovation Solution
A terminal is provided with a transmission unit to transmit a reference signal for positioning measurement in uplink and a control unit that assumes non-contiguous allocation of resources for the reference signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If contiguous resource allocation is used for reference signals, then resource allocation efficiency is improved, but operation compatibility with duplex methods deteriorates
Solution Approach 1:
The reference signal resources are divided into multiple non-contiguous segments rather than allocated as a single contiguous block. This segmentation allows the system to accommodate different duplex method requirements while maintaining resource allocation functionality.
Solution Approach 2:
The resource allocation parameter changes from contiguous to non-contiguous allocation. This parameter change enables compatibility with various duplex methods (FDD, TDD, XDD, FD) by allowing flexible resource distribution that adapts to different duplex operation requirements.
2Adaptability or versatility
If duplex methods are supported, then system flexibility is improved, but resource allocation clarity deteriorates
Solution Approach 1:
The patent establishes non-contiguous resource allocation as a predetermined rule for positioning reference signals before duplex method operations begin. This preliminary establishment of allocation rules provides clear, unambiguous resource allocation that works across all duplex methods, eliminating the need for complex dynamic allocation decisions.

AI summary
A terminal includes: a transmission unit configured to transmit, in uplink, a reference signal for positioning; and a control unit configured to assume that resources of the reference signal for positioning are to be non-contiguously allocated.
