UE Beam Applicability Reporting for Cooperation Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing beam applicability for user equipment cooperation, leading to excessive overhead and processing burdens due to the lack of shared resources and inappropriate beam configurations in multi-TRP scenarios.
Innovation Solution
The implementation of a method where user equipment (UE) transmits a beam applicability report indicating beam applicability information for physical channels, allowing for resource sharing and optimized communication operations based on this information, thereby reducing overhead and processing burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam applicability information is not shared in UE cooperation operations, then each UE must independently determine and report beam configurations, but this leads to excessive overhead and processing burdens
Solution Approach 1:
The patent combines beam applicability determination across multiple UEs by having the first UE share its determined beam applicability information with the second UE. This merging approach allows both UEs to benefit from a single beam configuration analysis rather than each independently determining beam parameters, thereby reducing overall processing burden while maintaining configuration accuracy.
Solution Approach 2:
The first UE performs beam applicability determination in advance and shares the results with the second UE before the second UE needs to make its own beam configuration decisions. This preliminary action eliminates redundant processing by providing ready-made beam configuration information that the second UE can directly utilize or adapt.
2Measurement precision
If each UE independently determines beam configurations for physical channels, then beam applicability is accurately assessed, but excessive overhead is generated due to redundant reporting
Solution Approach 1:
The patent merges beam applicability reporting by having the first UE share its determined beam applicability information with the second UE. This eliminates redundant beam configuration assessments and reports, reducing the quantity of overhead messages while maintaining accurate beam applicability assessment through the shared information from the first UE's measurements.
Solution Approach 2:
The second UE obtains beam applicability information by copying or receiving it from the first UE's determination results, rather than independently performing the same measurements and assessments. This copying approach maintains measurement precision while significantly reducing the overhead associated with redundant beam configuration reporting.
3Productivity
If resources are not shared between UEs in cooperation operations, then each UE has dedicated resources, but this increases overall system overhead and reduces efficiency
Solution Approach 1:
The patent merges resource utilization between UEs by enabling the second UE to use the first UE's determined beam applicability information for its own communication operations. This shared resource approach improves overall communication efficiency by eliminating redundant processing while the base station manages the coordination to maintain appropriate resource allocation and avoid conflicts.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam applicability report that indicates beam applicability information corresponding to one or more physical channels for a UE cooperation operation. The UE may communicate with at least one wireless communication device in the UE cooperation operation based at least in part on the beam applicability information. Numerous other aspects are described.
