Flexible Uplink Traffic Channel Resource Request Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently reporting uplink traffic channel resource requests due to the mismatch between the size of resource request reports and the varying needs of wireless terminals, leading to inefficiencies in resource allocation and increased latency.
Innovation Solution
The implementation of a flexible uplink traffic channel resource request structure that supports multiple request groups and varying report sizes, allowing for efficient communication of backlog information through dedicated control channels using different formats and modes, such as full-tone and split-tone formats, to balance report size and frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large bit size request report is used to represent a large amount of uplink traffic channel request information, then the information completeness is improved, but the overhead increases and reporting frequency decreases, leading to increased latency
Solution Approach 1:
The patent segments the uplink traffic channel request information into multiple groups (first uplink traffic channel request group and second uplink traffic channel request group). Each group can be reported separately using compact bit representations, allowing the system to convey comprehensive information without requiring a single large-bit report, thus reducing overhead and enabling more frequent reporting.
Solution Approach 2:
The patent introduces dynamic selection between different request report formats (first format and second format) based on system conditions. The wireless terminal can dynamically choose which format to use for reporting different request groups, optimizing the balance between information completeness and reporting overhead according to current network conditions and traffic requirements.
2Productivity
If a small bit size request report is used to reduce overhead, then the reporting frequency can increase, but the information completeness decreases, which is insufficient for applications requiring communication of large amounts of request information
Solution Approach 1:
The patent divides the request information into multiple segments (different request groups) that can be reported separately. This allows the system to use compact small-bit reports for each segment while collectively conveying comprehensive information, thus maintaining high reporting frequency without sacrificing information completeness.
Solution Approach 2:
The patent adds a group dimension to the request reporting structure by introducing multiple request groups (first and second uplink traffic channel request groups). This dimensional expansion allows the system to report information in a structured hierarchical manner, enabling frequent reporting of individual groups while maintaining overall information completeness across all groups.
3Device complexity
If a single uplink traffic channel request group is used to simplify the request structure, then the device complexity is reduced, but the adaptability to diverse wireless terminal needs and applications decreases
Solution Approach 1:
The patent implements dynamic adaptability by allowing the wireless terminal to selectively report different request groups based on current needs. The system can dynamically adjust which request groups are active and reported, providing flexibility to accommodate diverse application requirements while maintaining a relatively simple base structure that can be configured as needed.
Solution Approach 2:
The patent creates a universal request reporting framework that can handle multiple types of uplink traffic channel requests through the grouped structure. The same basic request mechanism can serve different applications and traffic types by configuring different request groups, thus achieving multi-functionality without requiring separate mechanisms for each application type.

AI summary
An uplink dedicated control channel reporting structure includes a plurality of different bit size reports, e.g. 1 bit, 3 bit and 4 bit reports, for reporting a wireless terminal's backlog information of uplink traffic request group queues. Smaller bit size reports are transmitted more frequently than larger reports. A 1 bit request report indicates whether or not there are any MAC frames of information to be communicated in a set of two request group queues. A 3 bit request report indicates an amount of backlog information corresponding to a first set of request group queues and a second set of request group queues. A 4 bit request report indicates an amount of backlog information corresponding to a set of request group queues. The 4 bit request report is capable of reporting information on any of a plurality of uplink traffic channel request group queues being maintained by the wireless terminal.
