Beam Switching Priorities for PRS Accuracy and Data Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in accurately determining user equipment (UE) location and transferring high-priority data due to limitations in beam switching capabilities, particularly when positioning reference signal (PRS) operations consume available beam switching opportunities, leading to inaccurate location estimates and resource wastage.
Innovation Solution
The UE selects transmission types for beam switching based on priority, prioritizing PRS measurements and high-priority data transmission to optimize beam usage within a slot, allowing for accurate location determination and efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam switching opportunities are allocated to PRS operations, then location estimation accuracy is improved, but data transmission efficiency deteriorates
Solution Approach 1:
The patent implements dynamic beam switching where the UE adapts beam selection based on transmission type priorities. The system dynamically adjusts beam usage between PRS operations and data transmission according to current slot requirements, rather than using static beam allocation. This allows the system to optimize location estimation accuracy when PRS is prioritized while maintaining data transmission efficiency when data is prioritized.
Solution Approach 2:
The patent changes the parameter of beam switching behavior based on transmission type priority. By introducing priority-based beam switching, the system modifies how beams are selected and switched depending on whether the current transmission is for PRS or data, resolving the contradiction between location accuracy and data efficiency through parameter adaptation.
2Adaptability or versatility
If multiple beam switches are performed within a slot, then communication flexibility is improved, but beam switching capability limitations cause resource wastage
Solution Approach 1:
The patent applies preliminary action by determining transmission type priorities before performing beam switching operations. The UE identifies whether PRS or data transmission has higher priority in advance, then plans beam switching accordingly to avoid unnecessary switches and conserve resources. This preliminary determination prevents resource wastage while maintaining communication flexibility.
Solution Approach 2:
The UE autonomously manages its own beam switching based on internal priority determination without requiring external control. The device self-regulates beam switching behavior according to transmission type priorities, optimizing resource usage while maintaining flexibility in communication operations.
3Measurement precision
If beam switching is optimized for PRS operations, then location determination accuracy is improved, but high-priority data transmission may be delayed
Solution Approach 1:
The system dynamically adjusts beam allocation based on real-time transmission priorities. When high-priority data transmission is detected, the system dynamically shifts beam resources from PRS operations to data transmission, preventing delays. This dynamic adaptation resolves the contradiction by allowing the system to favor location accuracy when PRS is prioritized while protecting high-priority data from delay.
Solution Approach 2:
The patent implements feedback mechanisms where the UE monitors transmission priorities and adjusts beam switching behavior accordingly. The system receives feedback about transmission type priorities and uses this information to optimize beam allocation, ensuring that location determination accuracy is maintained when needed while high-priority data transmission is protected from delays.
