Terminal System Message Update Segmentation for Redcap Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly with Redcap terminals, system message updates trigger unnecessary power consumption as all terminals update messages despite only some needing changes, and the varying number of antennas in Redcap terminals further complicates this, leading to power waste.
Innovation Solution
A method utilizing multiple information fields in Paging DCI to specifically instruct different types of terminals to update system messages based on their type, avoiding unnecessary updates and optimizing power usage by targeting only necessary updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all terminals update system messages when a change is detected, then system message consistency is maintained, but power consumption increases unnecessarily for terminals that do not need updates
Solution Approach 1:
The system message update indication is segmented into multiple information fields, where each field corresponds to a specific terminal type. This allows the network device to selectively indicate updates for different terminal types (e.g., Redcap terminals vs. non-Redcap terminals) rather than broadcasting a universal update to all terminals, thereby reducing unnecessary power consumption while maintaining consistency for affected terminals.
Solution Approach 2:
Different information fields within the system message update indication are designed with different lengths and meanings based on terminal type. For example, the first information field may be 1 bit for non-Redcap terminals while the second information field may be 2 bits for Redcap terminals. This local differentiation ensures that each terminal type receives only the relevant update information it needs, avoiding unnecessary power consumption.
2Reliability
If system message updates are broadcast to all terminal types, then update coverage is complete, but information efficiency decreases due to redundant updates
Solution Approach 1:
The update indication is divided into multiple segmented information fields, each tailored to specific terminal types. This segmentation ensures that update information is transmitted efficiently without redundancy, as each field contains only the relevant update indication for its corresponding terminal type, thereby improving information efficiency while maintaining complete coverage.
Solution Approach 2:
The patent changes the parameters of the information fields based on terminal type characteristics. Different terminal types are assigned different information field lengths and update conditions (e.g., 1 bit for non-Redcap, 2 bits for Redcap). This parameter differentiation optimizes information transmission efficiency by avoiding redundant update indications while ensuring all terminal types receive appropriate updates.
3Use of energy by moving object
If multiple information fields are used to differentiate terminal types, then power consumption is optimized, but message structure complexity increases
Solution Approach 1:
The message structure is segmented into multiple information fields with clear demarcations, where each field corresponds to a specific terminal type. This segmentation, while increasing structure complexity, provides a systematic and organized approach that simplifies terminal-side processing, as terminals can directly identify and process only their relevant fields without parsing the entire message structure.
Solution Approach 2:
The system message update indication structure is designed to serve multiple terminal types simultaneously through a universal framework. The same basic message structure can accommodate different terminal types by activating appropriate information fields, reducing the need for entirely separate message formats and thereby managing complexity while maintaining power optimization benefits.
