UE Cross-Link Interference Measurement Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring user equipment (UE) for cross-link interference measurement and reporting, particularly due to limitations in UE processing capabilities and the latency associated with higher layer signaling.
Innovation Solution
The described techniques involve configuring a UE for cross-link interference measurement and reporting based on its processing capabilities, where the UE transmits control signaling indicating its processing capability, receives configuration signaling from the network, and generates and reports cross-link interference measurements accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If higher layer signaling is used for UE configuration, then configuration can be provided, but latency is increased
Solution Approach 1:
The patent extracts the essential configuration parameters from higher layer signaling and places them directly in the downlink control information (DCI) message. This allows the most time-critical configuration elements to be transmitted with lower latency while maintaining the ability to provide more detailed configuration through higher layer signaling when needed.
Solution Approach 2:
The configuration information is segmented into two parts: essential parameters included in the DCI message for low-latency delivery, and supplementary parameters provided through higher layer signaling. This segmentation allows the system to balance between latency reduction and comprehensive configuration.
2Measurement precision
If UE processing capability is not considered, then configuration can be simplified, but measurement and reporting accuracy deteriorates
Solution Approach 1:
The patent applies local quality by tailoring the configuration parameters specifically to each UE's processing capability. The network entity configures the UE based on its reported capability level, providing optimized parameters that match the UE's actual processing abilities, thereby improving measurement accuracy without imposing excessive complexity.
Solution Approach 2:
The system changes configuration parameters based on the UE's processing capability. The UE reports its capability, and the network adjusts the configuration parameters accordingly, allowing the same system to adapt to different UE capabilities and maintain optimal measurement accuracy across diverse devices.
3Reliability
If cross-link interference measurement is implemented, then network reliability is improved, but UE processing load increases
Solution Approach 1:
The patent implements partial action by configuring the UE to perform cross-link interference measurement only to the extent of its processing capability. The UE reports its capability, and the network configures appropriate measurement parameters that achieve sufficient reliability without demanding more processing power than the UE can provide.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit control signaling indicating a processing capability of the UE for cross-link interference measurement and reporting. The UE may receive, in response to the control signaling indicating the processing capability, control signaling indicating a configuration of the UE for the cross-link interference measurement and reporting. The UE may transmit, to a network entity, a message indicating a cross-link interference measurement generated by the UE according to the configuration.
