Transmission Resource Indication for Time-Constrained Channel Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an effective method for a terminal device to inform a base station about unused physical channel occasions within a cycle, leading to inefficiencies in resource allocation.
Innovation Solution
A terminal device transmits first information in a first physical channel occasion to indicate at least one unused second physical channel occasion within a first cycle, subject to a first time constraint condition, allowing the network device to efficiently reallocate resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a terminal device reports all unused physical channel occasions in a cycle, then the network device can reallocate resources more effectively, but the network device may experience processing delays when the reported occasions exceed its processing capability
Solution Approach 1:
The patent segments the reporting process by introducing time constraint conditions that divide unused physical channel occasions into reportable and non-reportable categories. The terminal device only reports unused occasions that satisfy the time constraint condition (where the time interval between the unused occasion and the reporting occasion is within a threshold), thereby segmenting the reporting workload to match network device processing capabilities and avoid overwhelming the network with excessive reporting data.
Solution Approach 2:
The patent applies preliminary action by pre-defining time constraint conditions and time interval thresholds before the reporting process. The network device configures the time interval threshold in advance, and the terminal device uses this pre-set constraint to determine which unused physical channel occasions are suitable for reporting. This preliminary setup ensures that only appropriately timed reports are generated, preventing processing delays caused by excessive or improperly timed reporting.
2Productivity
If a terminal device reports unused physical channel occasions without time constraints, then more resources can be reallocated, but invalid reporting increases and system efficiency decreases
Solution Approach 1:
The patent applies local quality by making the reporting capability location-dependent in the time domain. Different unused physical channel occasions have different reportability based on their temporal relationship with the reporting occasion. Specifically, only unused occasions within the time constraint condition (within the threshold interval) are considered valid for reporting, while those outside the interval are excluded. This local differentiation ensures that reporting is context-appropriate and reduces invalid reporting.
Solution Approach 2:
The patent uses preliminary action by pre-establishing time constraint conditions that define which unused physical channel occasions are valid for reporting. The time interval threshold is configured in advance, and the terminal device applies this constraint before generating reports. This preliminary filtering prevents invalid reporting by ensuring that only temporally appropriate unused occasions are reported, thereby maintaining information quality and reducing waste.
3Productivity
If the network device processes all reported unused physical channel occasions, then resource utilization improves, but the device complexity and processing load increase
Solution Approach 1:
The patent segments the processing load by introducing time constraint conditions that divide unused physical channel occasions into manageable subsets. The terminal device only reports unused occasions that satisfy the time constraint condition, thereby segmenting the reporting data to match network device processing capabilities. This segmentation reduces the overall processing load while maintaining effective resource reallocation for the reportable subset.
Solution Approach 2:
The patent applies partial action by having the terminal device report only a subset of unused physical channel occasions—specifically, those that satisfy the time constraint condition—rather than reporting all unused occasions. This partial reporting approach reduces the processing load on the network device while still achieving effective resource utilization for the reported subset, avoiding the complexity of processing excessive data.
