Wireless Terminal Reporting Alternative Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple access wireless communications systems, wireless terminals face challenges in efficiently communicating uplink traffic channel information due to limited air link resources and varying traffic channel reporting needs, necessitating the ability to select between different reporting alternatives without changing the bit size of request reports.
Innovation Solution
The implementation of a method and apparatus that allows wireless terminals to select from multiple reporting alternatives for uplink traffic reports, using predetermined or dynamically calculated priority levels to determine which information to report, thereby optimizing resource allocation and adapting to changing traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed bit size request report format is used, then the air link resource allocation is simplified, but the system cannot adapt to different traffic channel reporting needs of multiple applications
Solution Approach 1:
The request report is segmented into multiple reporting alternatives, each corresponding to different groupings of traffic channels. The N-bit report format is divided into different mappings where each mapping represents a specific grouping scenario. This allows the system to select appropriate reporting alternatives based on current traffic needs while maintaining a fixed overall report structure.
Solution Approach 2:
The system dynamically selects between different reporting alternatives based on current traffic conditions and application requirements. The mapping definition changes dynamically to reflect different traffic channel grouping scenarios, allowing the fixed bit size format to adapt to varying reporting needs without changing the fundamental report structure.
2Adaptability or versatility
If multiple reporting alternatives are supported, then different traffic channel grouping needs can be met, but the complexity of selecting between alternatives increases
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple reporting alternatives and their corresponding mappings before actual traffic reporting occurs. Each alternative is prepared in advance with its specific bit mapping definition, allowing the selection process to simply choose from pre-configured options rather than creating mappings dynamically during operation.
Solution Approach 2:
The wireless terminal autonomously selects the appropriate reporting alternative based on its own traffic channel conditions and application requirements. The terminal self-determines which grouping scenario applies and selects the corresponding mapping without requiring complex external coordination or control.
3Productivity
If the number of bits for the report is kept fixed, then air link resource efficiency is improved, but the ability to communicate different types of backlog information is limited
Solution Approach 1:
The fixed N-bit report format achieves multi-functionality by supporting multiple reporting alternatives, each capable of conveying different types of backlog information. The same bit size report can universally represent various traffic channel grouping scenarios and backlog conditions through different mappings, eliminating the need for variable bit sizes while maintaining comprehensive information coverage.

AI summary
Methods and apparatus related to wireless terminal reporting alternative selection for a fixed bit size control information request report, e.g., a 4 bit uplink traffic channel request report, are described. A wireless terminal maintains a plurality of different request groups corresponding to uplink traffic to be transmitted. The same request report format includes a plurality of reporting alternatives, different reporting alternatives corresponding to different request groups. Backlog can and sometimes does exist simultaneously corresponding to request groups corresponding to different reporting alternatives. The wireless terminal uses priority information associated with the request groups having non-zero backlog to select a reporting alternative. In some embodiments, at least some of the request groups have priorities which are calculated by the wireless terminal and change as a function of determined transmission deadline information.
