Adaptive Wireless Reporting Format for Control Channel Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in reporting information, leading to overhead that reduces the use of available radio resources for data transmission, as terminals must convey various types of information such as channel quality, resource requests, and interference levels.
Innovation Solution
The system employs adaptive reporting formats based on terminal operating conditions, using a dedicated control channel to efficiently send reports through repetitive and condition-dependent strategies, optimizing the sequence and frequency of report transmission to minimize overhead and maximize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals send reports repetitively to convey information such as channel quality, resource requests, and interference levels, then the system can maintain proper operation and allocate resources effectively, but the reporting overhead increases and reduces the available radio resources for data transmission
Solution Approach 1:
The patent implements periodic reporting where terminals send reports at regular intervals rather than continuously. The reporting is triggered by specific events or time intervals, allowing the system to maintain operational reliability while reducing the frequency of transmissions and preserving radio resources for data communication.
Solution Approach 2:
The patent dynamically adjusts reporting parameters such as reporting frequency, report size, and report type based on channel conditions, terminal mobility, and system load. When channel conditions are good or terminals are stationary, reporting frequency is reduced. When conditions deteriorate or terminals move rapidly, reporting frequency increases, optimizing the balance between reliability and resource efficiency.
2Productivity
If terminals send detailed reports frequently to ensure adequate service and proper system operation, then the base station can make accurate resource allocation decisions, but the overhead in the system increases
Solution Approach 1:
The patent implements partial reporting where terminals send only the necessary portion of information based on current needs. Instead of sending complete reports every time, terminals transmit only changed parameters or differential values, reducing overhead while maintaining sufficient information for effective resource allocation decisions.
Solution Approach 2:
The reporting mechanism is made dynamic, adapting to current system conditions. The base station can request specific types of reports based on immediate needs, and terminals adjust their reporting behavior accordingly. This dynamic approach ensures that resource allocation decisions are based on timely and relevant information without the overhead of sending all possible report types continuously.
3Ease of manufacture
If the system uses fixed reporting formats for all terminals, then the implementation is simple and consistent, but the system cannot adapt to different terminal capabilities, environments, and traffic requirements
Solution Approach 1:
The patent divides the reporting system into multiple formats and types, each optimized for specific scenarios. Different report formats are defined for different terminal capabilities, mobility conditions, and traffic types. The base station can select and assign appropriate reporting formats to individual terminals based on their specific requirements, achieving both simplicity through standardized formats and adaptability through format selection.
Solution Approach 2:
The patent creates a universal reporting framework that can handle multiple terminal types, environments, and traffic requirements through a single adaptable system. The framework defines a set of standardized reporting formats that can be selectively applied, allowing the same basic mechanism to serve diverse needs without requiring completely separate systems for each scenario.

AI summary
Techniques for sending reports in a wireless communication system are described. Reports may be sent repetitively in accordance with a reporting format. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The reporting format indicates a specific sequence of reports sent in specific locations of a control channel frame. The terminal generates a set of reports for each reporting interval and arranges the set of reports in accordance with the reporting format. The terminal repetitively sends a plurality of sets of reports in a plurality of reporting intervals. Reports may also be sent adaptively based on operating conditions. An appropriate reporting format may be selected based on the operating conditions of the terminal, which may be characterized by environment (e.g., mobility), capabilities, QoS, and/or other factors.
