Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NR network resource indication schemes are complex and non-unified, failing to consider beam-specific transmission direction, leading to inefficient spectrum utilization across different duplex methods like FDD, TDD, and SBFD.
Innovation Solution
A method involving beam/MIMO layer dependent Rx/Tx configuration using 3D/4D spectrum resource indication, incorporating time, frequency, spatial, and optionally power domain information for unified resource utilization across full duplex, SBFD, TDD, and FDD.

Engineering Contradiction Analysis
1Adaptability or versatility
If current NR network uses 2D spectrum utilization (time-domain and frequency-domain), then resource indication can be provided, but beam-specific transmission direction is not considered and spectrum utilization is non-unified across different duplex methods
Solution Approach 1:
The patent extends the traditional 2D time-frequency resource indication to a 3D time-frequency-spatial resource indication by adding the spatial domain (beam direction). This dimensional extension enables the system to indicate not only when and where resources are allocated but also in which spatial direction beams should be configured, thereby achieving unified spectrum utilization across FDD, TDD, and SBFD duplex methods while considering beam-specific transmission directions.
Solution Approach 2:
The patent proposes a unified resource indication scheme that can accommodate multiple duplex methods (FDD, TDD, SBFD) and beam configurations through a single framework. The 3D resource indication structure serves multiple functions: it indicates time resources, frequency resources, spatial resources, and beam-specific transmission directions simultaneously, making the system adaptable to various duplex schemes without requiring separate indication mechanisms for each.
2Productivity
If 3D/4D spectrum resource indication is used with beam-specific transmission direction indication, then unified spectrum utilization is achieved, but resource indication complexity increases
Solution Approach 1:
The patent introduces the spatial dimension to the traditional time-frequency resource grid, creating a 3D resource indication structure. This adds beam direction information to the resource indication, enabling the system to efficiently allocate and indicate resources across different spatial directions while maintaining unified spectrum utilization. The spatial dimension allows the system to distinguish between different beam directions without requiring separate indication mechanisms.
3Adaptability or versatility
If multiple duplex methods (FDD, TDD, Full Duplex, SBFD) are supported with different frame structure configurations, then flexibility is improved, but the configurations become very complicated and non-unified
Solution Approach 1:
The patent proposes a unified frame structure configuration that can accommodate multiple duplex methods (FDD, TDD, Full Duplex, SBFD) through a single 3D resource indication framework. Instead of requiring separate configuration mechanisms for each duplex method, the system uses beam-specific transmission direction indication within the 3D resource grid to adapt to different duplex scenarios, thereby reducing configuration complexity while maintaining versatility.
