UE Capability Reporting for Multi-Domain Resource Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in utilizing UE resources due to under-reporting of capabilities and idle resources, leading to suboptimal utilization and underutilization of time, frequency, and spatial domains.
Innovation Solution
UEs transmit control messages indicating multi-dimensional resource reuse capabilities across time, frequency, and spatial domains, adapting resources accordingly based on configuration or scheduling changes.

Engineering Contradiction Analysis
1Productivity
If UE resources are allocated statically without capability reporting, then device complexity is reduced, but resource utilization efficiency deteriorates
Solution Approach 1:
The UE capability reporting is segmented into multiple dimensions (time domain, frequency domain, spatial domain) allowing the network to selectively request and process only relevant capability information for current scheduling needs, reducing overall complexity while improving resource utilization
Solution Approach 2:
The system transitions from static resource allocation to dynamic resource allocation based on real-time UE capability reporting. The UE adapts its resource usage across different domains dynamically, allowing the network to optimize resource utilization according to actual device capabilities and channel conditions
2Productivity
If UE under-reports capabilities to simplify configuration, then ease of operation is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The UE reports capabilities with different levels of detail for different domains (time, frequency, spatial) based on current operational context. This allows the network to obtain precise capability information where needed while avoiding unnecessary complexity in domains where full capability reporting is not required
Solution Approach 2:
The UE performs capability reporting in advance before actual resource allocation, allowing the network to have complete capability information available for optimal resource scheduling decisions without adding complexity to real-time operation
3Productivity
If idle resources are not reused across domains, then reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent enables UE resources to serve multiple functions across different domains. Resources allocated in one domain (e.g., time domain) can be reused in other domains (e.g., frequency or spatial domain) when idle, allowing the same physical resources to contribute to overall system throughput through multi-dimensional utilization
Solution Approach 2:
The system recovers idle resources from one domain and reallocates them to other domains where they are needed. When resources become idle in the time domain, they are recovered and can be reused in frequency or spatial domains, ensuring continuous productive utilization without compromising reliability

AI summary
Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may transmit a first control message indicative of a capability of the UE to support re-use of UE resources across different dimensions, where the first control message is configured to report capabilities of the UE to support re-use of UE resources in a time domain, a frequency domain, a spatial domain, or any combination thereof. Additionally, the UE may receive a second control message indicative of a change in configuration of the UE or a change in scheduling of the UE and may adapt one or more resources in the time domain, the frequency domain, the spatial domain, or any combination thereof, in accordance with the change in configuration or the change in scheduling based on the capability of the UE to support re-use of UE resources across different dimensions.
