UE Capability Negotiation for Multi-System Resource Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple radio access systems, such as 5G and 4G networks, are merged, existing technologies lack an effective mechanism to coordinate UE capabilities across different systems, potentially exceeding the maximum capability of user equipment (UE) and inefficiently allocate radio resources.
Innovation Solution
A method for UE capability negotiation is introduced, where the UE reports individual capabilities for each radio access network and a merged capability across multiple systems to the network, allowing the master base station to recommend suitable configuration parameters to the secondary base station for optimal resource management and radio configuration.

Engineering Contradiction Analysis
1Adaptability or versatility
If UE capability negotiation mechanism is not implemented in multiple systems merge scenario, then each system can operate independently with full capability, but the maximum UE capability may be exceeded and radio resources cannot be effectively coordinated
Solution Approach 1:
The UE capability information is segmented into two distinct parts: individual system capabilities (e.g., LTE capability, NR capability) and merged capability. This segmentation allows the network to understand both the standalone capability of each radio access system and the combined capability when multiple systems are merged, enabling proper resource coordination without exceeding UE maximum capability.
Solution Approach 2:
The master base station acts as an intermediary that collects capability information from the UE, analyzes both individual and merged capabilities, and coordinates resource allocation across multiple systems. The master base station forwards relevant capability information to secondary base stations, ensuring that resource allocation decisions consider the overall UE capability constraints while enabling multi-system operation.
2Productivity
If UE reports detailed capability information for each system, then resource allocation can be optimized, but the capability negotiation complexity increases
Solution Approach 1:
The capability reporting mechanism is segmented into structured components: individual system capabilities reported separately and merged capability reported as a combined parameter. This segmentation allows the network to process capability information systematically, analyzing individual capabilities for specific resource allocation decisions while using merged capability for overall coordination, thereby optimizing resource allocation without overwhelming complexity.

AI summary
A method for UE capability negotiation, a UE and a base station are provided. The UE reports individual capabilities of the UE for respective radio access networks in multiple systems and a merged capability of the UE for all radio access networks in the multiple systems.
