Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separate indication of time-domain resources for each hop in multi-hop wireless communication leads to high overheads and resource wastage.
Innovation Solution
A method that configures and indicates time-domain resources for M-hop transmission using multiple pieces of information, ensuring non-overlapping and efficient utilization, with different information carried on control and data channels to reduce overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-domain resources for each hop are separately indicated, then transmission reliability is improved, but indication overhead increases
Solution Approach 1:
The patent combines the indication of time-domain resources for multiple hops into a single indication information structure. Instead of separately indicating resources for each hop, the system uses a unified indication mechanism that efficiently conveys resource allocation for the entire M-hop transmission path, thereby reducing overhead while maintaining transmission reliability.
Solution Approach 2:
The indication information is designed to serve multiple functions simultaneously - it indicates time-domain resources for all M hops in a single structure, enabling the system to manage multi-hop transmission resource allocation efficiently without requiring separate indication mechanisms for each hop.
2Adaptability or versatility
If separate indication is used for each hop, then resource configuration flexibility is improved, but overhead and resource wastage increase
Solution Approach 1:
The patent merges the resource configuration for multiple hops into a single integrated indication mechanism, eliminating redundant information and reducing the overall resource consumption while preserving the flexibility needed for adaptive resource allocation across different hops.

AI summary
This application provides a resource indication method and a communication apparatus. The method is applied to the field of communication technologies. The method includes: obtaining indication information that indicates a configuration of time-domain resources for M-hop transmission between a first apparatus and a target apparatus, where the M-hop transmission includes a transmission between the first apparatus and a second apparatus, the indication information includes first information indicating a configuration of at least two time-domain resources that belong to a time-domain transmission resource and/or a time-domain reserved resource for the M-hop transmission, and M is an integer greater than 1; and sending the indication information to the second apparatus. The method described in this application can reduce time-domain resource indication overheads.
