Multiple Repetitive Resources for RF Calibration Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Performing calibration of RF components in wireless communication devices can cause interference with other devices and is challenging to schedule effectively, particularly due to the need to temporarily suspend payload data transmission during uplink calibration gaps.
Innovation Solution
A method that allows wireless communication devices to use multiple repetitive resources for calibration, selecting an appropriate resource for calibration, and scheduling the uplink calibration gap to minimize interference and simplify resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calibration is performed at a UE, then RF components can be calibrated, but interference is caused at other UEs and/or base station
Solution Approach 1:
The patent segments the calibration process by dividing time into different intervals: calibration gaps where payload transmission is suspended for calibration, and data transmission intervals. This temporal segmentation allows calibration to occur without continuously interfering with other devices, resolving the contradiction between calibration reliability and interference generation.
Solution Approach 2:
The patent introduces control messages as intermediaries between the UE and the network. These control messages carry calibration information and coordination data, enabling the network to manage calibration activities and minimize interference to other devices through coordinated control.
2Reliability
If uplink calibration gap is scheduled, then calibration can be performed, but scheduling becomes complicated
Solution Approach 1:
The patent applies preliminary action by pre-configuring calibration parameters and timing information in control messages before the actual calibration occurs. The network pre-establishes calibration gaps and resource allocations, eliminating the need for complex real-time scheduling decisions and reducing scheduling complexity.
Solution Approach 2:
The patent implements dynamic scheduling where calibration gaps can be adjusted based on network conditions and UE requirements. The system dynamically allocates calibration resources and timing, making the scheduling process more flexible and less complex compared to fixed scheduling approaches.
3Reliability
If payload data transmission is suspended for calibration, then calibration signals can be transmitted, but communication productivity decreases
Solution Approach 1:
The patent implements periodic calibration gaps interspersed with data transmission intervals. Instead of continuous suspension of payload transmission, calibration is performed periodically in dedicated gaps, maintaining overall communication productivity while ensuring calibration accuracy when needed.
Solution Approach 2:
The patent maintains continuity of useful action by alternating between calibration gaps and data transmission periods. The system ensures that payload data transmission resumes promptly after calibration, minimizing the impact on overall productivity and maintaining continuous communication functionality.
