Wireless Time Subunit Allocation for Flexible Resource Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the time domain resources allocated for data transmission are not flexible enough, leading to inefficient use based on the amount of data, as they typically occupy a fixed time interval per transport block, limiting the ability to adjust resource allocation according to data requirements.
Innovation Solution
A communication method that determines different time subunits within a time unit based on control information, allowing for flexible adjustment of time domain resources for data reception and transmission, enabling more efficient use of resources by allocating specific time subunits for different data blocks or processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed time interval is allocated for each transport block, then the resource allocation is simple and stable, but the time domain resource flexibility is insufficient and cannot be appropriately adjusted based on data amount
Solution Approach 1:
The time unit is divided into multiple time subunits, allowing the system to allocate resources at a finer granularity. Each transport block can be assigned to specific time subunits rather than occupying an entire time unit, enabling flexible adjustment of time domain resources based on data amount while maintaining manageable complexity through structured segmentation
Solution Approach 2:
The patent implements dynamic time domain resource allocation where the number and positioning of time subunits assigned to each transport block can be flexibly adjusted based on actual data requirements. This dynamic approach allows the system to adapt resource allocation to varying data amounts while using control information to manage the complexity of the allocation process
2Productivity
If one time unit is allocated per transport block, then the allocation mechanism is simple, but the data transmission efficiency is limited due to insufficient resource matching
Solution Approach 1:
Different time subunits within a time unit can be allocated to different transport blocks based on their specific data amounts and requirements. This local quality approach ensures that each transport block receives appropriate time resources matched to its needs, improving data transmission efficiency while minimizing time resource waste by avoiding allocation of excessive time units to small data blocks
3Adaptability or versatility
If time domain resources are fixed per transport block, then the system operation is stable and predictable, but the resource utilization cannot be optimized based on actual data requirements
Solution Approach 1:
Control information serves as an intermediary mechanism that manages the complexity of flexible time domain resource allocation. The control information carries indications about the number and positioning of time subunits assigned to each transport block, allowing the system to achieve adaptable resource allocation while maintaining ease of operation through standardized control signaling rather than complex direct scheduling
