Time Domain Resource Configuration via Segmented Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently configuring time domain resources with low signaling overheads, particularly when configuring multiple candidate time domain resources for terminal devices, which can lead to increased signaling burdens.
Innovation Solution
A method and apparatus for configuring time domain resources by receiving time domain resource allocation indication information to determine multiple candidate resources based on preconfigured rules, reducing signaling overheads through efficient indication of start symbol positions and lengths, allowing for flexible allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more candidate time domain resources are configured for terminal devices, then resource allocation flexibility is improved, but signaling overhead increases
Solution Approach 1:
The patent segments the time domain resource configuration into two parts: a preconfigured resource pool defined by start symbol position and length parameters, and a dynamic indication that selects specific resources from this pool. This segmentation allows the system to support multiple candidate resources without transmitting complete resource allocation information for each candidate, thereby reducing signaling overhead while maintaining allocation flexibility.
Solution Approach 2:
The patent implements preliminary action by preconfiguring a pool of candidate time domain resources before actual data transmission. The network device预先 defines multiple candidate resources with different start symbol positions and lengths, and stores them in a predefined format. When allocation is needed, the terminal only needs to receive a compact indication to select from this pre-prepared pool, eliminating the need to transmit detailed resource description information and thus reducing signaling overhead.
2Quantity of substance
If traditional resource allocation methods are used to indicate multiple candidate resources, then resource coverage is improved, but indication information size increases
Solution Approach 1:
The patent uses copying by creating a predefined template or pattern for time domain resource allocation that can be reused across multiple candidate resources. Instead of transmitting unique allocation information for each candidate, the system defines a reusable indication format that references the preconfigured resource pool. This copying approach allows the same indication structure to represent multiple different resource allocations, thereby supporting a larger number of candidate resources without proportionally increasing indication information size.

AI summary
A time domain resource configuration method, an apparatus, and a system are provided, to send, by a network device, time domain resource allocation indication information to a terminal device. The time domain resource allocation indication information is used to indicate N1 time domain resource allocations, where N1 is an integer greater than or equal to 1. The N1 time domain resource allocations may be used to determine N2 candidate time domain resources, where N2 is an integer greater than N1.
