Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional resource indication methods (consecutive or distributed) are used, then the indication is simple and clear, but the resource allocation is limited to only one subframe
Solution Approach 1:
The patent extends resource indication from a single subframe (one-dimensional) to multiple subframes (multi-dimensional) by introducing time-domain resource position indicators and subframe offset indicators. This dimensional expansion allows the same indication mechanism to cover both single-subframe and multi-subframe scenarios, resolving the contradiction between simplicity and versatility.
Solution Approach 2:
The patent creates a universal resource indication mechanism that can function in both single-subframe and multi-subframe modes. By using a unified indication format that includes optional time-domain parameters, the system achieves multi-functionality without requiring separate indication methods for different scenarios, thus balancing adaptability and complexity.
2Adaptability or versatility
If resource indication is extended to multiple subframes, then the resource allocation flexibility is improved, but the indication information complexity increases
Solution Approach 1:
The patent segments the resource indication into distinct components: frequency-domain resource indicators, time-domain resource position indicators, and subframe offset indicators. This segmentation allows the system to include only necessary elements for multi-subframe indication while maintaining compatibility with single-subframe scenarios, reducing information overhead while enabling extended functionality.
Solution Approach 2:
The patent implements partial action by making the time-domain resource position and subframe offset indicators optional or conditional. When single-subframe indication is sufficient, these additional parameters are not transmitted, avoiding unnecessary information overhead. When multi-subframe allocation is needed, these parameters are added to provide the required flexibility.
3Productivity
If only single subframe resource indication is supported, then the system complexity is low, but the resource utilization efficiency is limited
Solution Approach 1:
The patent introduces dynamic resource allocation across multiple subframes by enabling the indication mechanism to adaptively select between single-subframe and multi-subframe modes. The system dynamically adjusts the resource allocation scope based on traffic requirements, achieving higher resource utilization efficiency while maintaining manageable complexity through conditional parameter inclusion.

AI summary
Embodiments of this application relate to the field of wireless communications technologies, and provide a resource indication method, a resource determining method, and a related apparatus, to indicate transmission resources in two subframes. The method includes: determining, by a transmitting device, a first time domain resource and a second time domain resource; and sending, by the transmitting device, first resource indication information on a third time domain resource, where the first resource indication information is used to indicate a position of the first time domain resource and a position of the second time domain resource, and a value of the first resource indication information is determined by using the position of the first time domain resource and the position of the second time domain resource. According to this solution, the transmitting device may determine the value of the first resource indication information by using the position of the first time domain resource and the position of the second time domain resource, and may indicate the two time domain resources by using the first resource indication information.
