Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems lack flexibility in adapting radio resource allocation to dynamic service and radio condition requirements, as they can only support one radio interface technology per carrier, making it difficult to efficiently manage different service quality and radio conditions.
Innovation Solution
The method involves user equipment (UE) determining target capability information for multiple air interface types, allowing the base station to flexibly allocate radio resources among these types, enabling support for multiple air interface technologies on a single carrier through frequency division, thereby adapting to dynamic service and radio conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one radio interface technology is supported per carrier, then system complexity is reduced and ease of operation is improved, but adaptability to different service quality requirements and radio conditions deteriorates
Solution Approach 1:
The patent segments the radio interface technology into multiple air interface types (first air interface type and second air interface type) that can be simultaneously supported on the same carrier. This segmentation allows the system to handle different service quality requirements through different interface types while maintaining manageable complexity through standardized processing methods.
Solution Approach 2:
The patent implements multi-functionality by enabling the same carrier to support multiple air interface types simultaneously. The base station and user equipment are designed to universally handle both first and second air interface types through unified capability information processing and scheduling mechanisms, allowing a single carrier to serve multiple service requirements.
2Adaptability or versatility
If multiple air interface types are supported on the same carrier, then adaptability to dynamic service requirements is improved, but capability information processing complexity increases
Solution Approach 1:
The patent applies preliminary action by having the user equipment determine target capability information for multiple air interface types in advance, before actual resource allocation occurs. The base station receives and processes this pre-determined capability information, enabling efficient scheduling decisions without complex real-time analysis during resource allocation.
Solution Approach 2:
The patent introduces capability information as an intermediary element that mediates between the user equipment's multiple air interface capabilities and the base station's scheduling decisions. This intermediary structure simplifies the interaction by providing standardized capability descriptors that the base station can process uniformly across different air interface types.
3Productivity
If frequency division is used to support multiple air interface types, then radio resource utilization flexibility is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation through frequency division, where the base station can flexibly assign different frequency resources to different air interface types based on real-time service requirements and radio conditions. This dynamic approach allows optimal radio resource utilization while the standardized capability information processing framework keeps allocation complexity manageable.

AI summary
Embodiments of this application provide a method for processing capability information of user equipment UE. The method includes: determining, by the UE, at least two air interface types supported by a same carrier as target air interface types; and sending, by the UE, air interface indication information to a base station based on the target air interface types, so that the base station schedules the UE based on the air interface indication information. Therefore, the method described in this application resolves a problem of processing air interface capability information of the UE, so that the UE may support a plurality of different air interface types on a same carrier, and therefore the base station may flexibly allocate a resource to the UE between a plurality of air interface types more flexibly based on the capability information of the UE, to more flexibly adapt to the dynamic requirements of the service and the radio condition.
