Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource partitioning methods are not applicable to a full-duplex working mode, which limits the ability to efficiently utilize frequency domain resources for simultaneous uplink and downlink transmissions.
Innovation Solution
A resource determination method that allows a terminal to divide a bandwidth part (BWP) into non-overlapping frequency domain resources, with different transmission directions for each resource, enabling a sub-band full-duplex working mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional resource partitioning methods are used, then resource allocation is simple and clear, but full-duplex working mode cannot be supported
Solution Approach 1:
The patent segments the frequency domain resources within a BWP into multiple non-overlapping frequency domain resource sets, where each set can be independently configured for different transmission directions. This allows simultaneous uplink and downlink transmissions in different frequency portions, enabling full-duplex operation while maintaining clear resource boundaries through systematic segmentation of the frequency spectrum.
Solution Approach 2:
The patent applies local quality by allowing different frequency domain resource sets within the same BWP to have different transmission direction configurations. Specifically, some frequency resources are designated for uplink while others are designated for downlink, creating local directional properties across the frequency spectrum that enable simultaneous bidirectional communication.
2Productivity
If frequency domain resources are divided for simultaneous uplink and downlink, then transmission efficiency improves, but resource configuration complexity increases
Solution Approach 1:
The patent creates a universal resource configuration framework where a single BWP can serve multiple functions by containing multiple frequency domain resource sets with different transmission directions. The same BWP structure accommodates both uplink and downlink resources simultaneously, allowing the system to adapt to different full-duplex operation modes without requiring separate dedicated resources for each direction.
3Object-affected harmful factors
If non-overlapping frequency domain resources are allocated for different directions, then interference is reduced, but resource utilization flexibility decreases
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the network to flexibly configure multiple frequency domain resource sets within a BWP according to actual transmission needs. The configuration can be dynamically adjusted to allocate different proportions of frequency resources to uplink or downlink directions based on traffic demands, while maintaining the non-overlapping property that prevents interference between simultaneous transmissions.

AI summary
A resource determination method, a device, a terminal, and a network side device are provided. The method includes: a terminal determining a range of first frequency domain resources and a range of second frequency domain resources within a BWP according to configuration information, where the first frequency domain resources and the second frequency domain resources within the BWP do not overlap, and a transmission direction corresponding to the first frequency domain resources is different from a transmission direction corresponding to the second frequency domain resources.
