Beam-Based IUC Resource Selection Using Beam Directivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam-based communication systems in FR2 suffer from reduced reliability and inefficiency in resource selection due to reliance on RSRP and priority measurements without considering beam directivity, leading to ineffective Inter-UE Coordination (IUC) operations.
Innovation Solution
A method for beam management and resource selection in Inter-UE Coordination (IUC) that considers beam directivity by determining preferred and non-preferred resource sets based on RSRP, RSRQ, SINR, and BLER thresholds, enhancing the reliability and efficiency of resource allocation.

Engineering Contradiction Analysis
1Reliability
If RSRP and priority measurements are used for resource selection, then resource allocation can be performed, but reliability is reduced due to not considering beam directivity
Solution Approach 1:
The patent changes the measurement parameters from conventional RSRP-only measurements to include RSRQ and SINR measurements that specifically account for beam directivity characteristics. This allows the system to evaluate resources based on multiple parameters including beam quality and directivity, thereby improving resource selection reliability without fundamentally changing the device architecture.
Solution Approach 2:
The patent performs preliminary beam pairing and beam quality assessment before resource selection. By pre-evaluating beam characteristics and establishing beam pairs with expected good quality, the system prepares beam directivity information in advance that can be used during resource selection, improving reliability while managing complexity through staged processing.
2Productivity
If beam pairing is performed without considering beam directivity, then Inter-UE Coordination operations can be executed, but efficiency is reduced due to ineffective resource selection
Solution Approach 1:
The patent implements feedback mechanisms where beam quality measurements (RSRQ, SINR) and beam pairing results are fed back into the resource selection process. This feedback loop ensures that beam directivity information is continuously updated and utilized, improving Inter-UE Coordination efficiency by preventing selection of resources that would perform poorly based on beam characteristics.
Solution Approach 2:
The patent segments the resource selection process into distinct phases: beam pairing phase, beam quality evaluation phase, and resource selection phase. By separating these functions and evaluating beam directivity in the intermediate phase, the system preserves beam information and uses it effectively to guide resource selection, improving overall coordination efficiency.

AI summary
A method for performing wireless communication by a first device and an apparatus supporting same are provided. The method may comprise the steps of: performing beam pairing with a second device; determining a resource set related to at least one of a preferred resource set or a non-preferred resource set; and transmitting information regarding the resource set to the second device. For example, a first resource which is determined on the basis of at least one beam other than the beam related to the beam pairing may be excluded from the preferred resource set or included in the non-preferred resource set.
