User Equipment Feedback for Uplink Grant Skipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is ambiguity regarding uplink grant skipping due to logical channel prioritization functions and resource allocation, leading to inappropriate resource management by base stations.
Innovation Solution
User equipment determines the availability of buffered data for transmission and communicates this information to the base station, including reasons for uplink grant skipping such as logical channel prioritization, processing limitations, and power constraints, allowing the base station to adjust resource allocation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If uplink grant skipping is implemented to save resources, then resource efficiency is improved, but ambiguity arises in resource management decisions
Solution Approach 1:
The patent implements a feedback mechanism where the user equipment sends an indication to the base station when skipping uplink grant transmission. This feedback informs the base station about the buffer status and the reason for skipping, eliminating the ambiguity in resource management decisions while maintaining resource efficiency benefits
2Adaptability or versatility
If buffered data cannot be transmitted over allocated resources, then resource allocation constraints are respected, but communication efficiency deteriorates
Solution Approach 1:
The patent enables the user equipment to provide feedback to the base station indicating that buffered data exists but cannot be transmitted over allocated resources, along with the specific reason (logical channel prioritization, processing limitations, or power constraints). This allows the base station to adjust future resource allocation to prevent data stalling, thereby maintaining communication efficiency while respecting resource allocation constraints
Solution Approach 2:
The patent allows the user equipment to proactively inform the base station about potential transmission issues before they cause significant data loss or delays. By providing advance notice of buffer status and constraints, the system can pre-adjust resource allocation to avoid communication inefficiencies
Data Source
AI summary
The disclosure relates a method comprising: determining that buffered data is available for transmission and cannot be transmitted over allocated resources; and causing information indicating that buffered data is available for transmission and cannot be transmitted over allocated resources to be transmitted over the allocated resources.
