Resource Block Set Configuration in Unlicensed Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially in unlicensed bands, base stations lack the ability to signal user equipment for full-duplex operations regarding resource block set configurations, leading to inefficiencies in resource allocation and communication.
Innovation Solution
The implementation of methods and apparatuses in user equipment and base stations to receive and transmit bits indicating the availability and direction of resource block sets, allowing for improved configuration and utilization of these resources through bitmaps and listen-before-talk procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base station allocates resources for full-duplex communication in unlicensed band, then communication capacity is improved, but base station lacks ability to signal UE for FD operations leading to configuration inefficiency
Solution Approach 1:
The UE autonomously determines the availability and transmission direction of RB sets by monitoring LBT outcomes and applying predefined rules, without requiring explicit signaling from the base station. This self-service mechanism resolves the contradiction by enabling full-duplex operation configuration efficiency while maintaining enhanced communication capacity
Solution Approach 2:
The system implements feedback through LBT (Listen-Before-Talk) procedures where the UE monitors channel availability and uses this feedback to autonomously configure RB sets for full-duplex operations, eliminating the need for base station signaling while maintaining efficient resource allocation
2Measurement precision
If base station signals UE for FD operations configurations, then resource allocation accuracy is improved, but in unlicensed band base station lacks signaling ability leading to information loss
Solution Approach 1:
Predefined rules and LBT procedures act as intermediaries between the base station's resource allocation intent and the UE's configuration actions. The UE uses these intermediaries to accurately determine RB set availability and transmission directions without direct signaling, preventing information loss while maintaining allocation accuracy
Solution Approach 2:
The system establishes predefined rules and LBT procedures in advance that enable the UE to autonomously configure RB sets with high accuracy. This preliminary action mechanism ensures that configuration information is available to the UE before actual full-duplex operations begin, eliminating the need for real-time base station signaling
