NR Gap Measurement Scaling for Colliding Measurement Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G or New Radio (NR) wireless systems face challenges in defining efficient scaling factors for synchronization signal block (SSB) measurements, leading to unnecessarily loose measurement delay requirements due to complex SMTC and MGRP combinations, particularly in scenarios with partially overlapped SMTCs.
Innovation Solution
Implementing a simplified framework that restricts SMTC and MGRP combinations to SMTC combinations, grouping measurements into groups, defining per-UE and per-FR based inter-frequency cell identification requirements, and using a scaling factor to account for colliding measurement objects (MOs) to optimize measurement efficiency and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SMTC and MGRP combinations are supported for flexible measurement configurations, then measurement flexibility and adaptability are improved, but measurement delay requirements become unnecessarily loose and complexity increases
Solution Approach 1:
The patent changes the parameter of SMTC configuration by limiting the number of partially overlapped SMTCs to a maximum of two per UE or per-FR. This parameter change resolves the contradiction by maintaining measurement flexibility for the most common scenarios while preventing the measurement delay from becoming unnecessarily loose due to excessive configuration options.
2Adaptability or versatility
If multiple SMTC and MGRP combinations are supported for flexible measurement configurations, then adaptability is improved, but system complexity increases
Solution Approach 1:
By changing the parameter to limit SMTC overlapping to a maximum of two per UE or per-FR, the patent reduces configuration complexity while preserving essential measurement flexibility. This parameter constraint simplifies the system by eliminating the need to handle numerous complex SMTC and MGRP combinations.
3Measurement precision
If per-UE and per-FR based inter-frequency cell identification requirements are defined with scaling factors, then measurement precision is improved, but calculation complexity increases
Solution Approach 1:
The patent introduces a scaling factor parameter that is applied uniformly to per-UE and per-FR based inter-frequency cell identification requirements. This parameter change improves measurement precision by accounting for colliding measurement objects while keeping the calculation method systematic and manageable through the use of a single scaling factor.
Solution Approach 2:
The scaling factor serves multiple functions: it adjusts measurement delay requirements for per-UE configurations, adjusts requirements for per-FR configurations, and accounts for colliding measurement objects. This universal parameter reduces calculation complexity by providing a single mechanism to handle multiple adjustment needs.

AI summary
There is provided one or more computer-readable media (CRM) having instructions that, when executed by one or more processors, cause an access node to: determine a number of management objects (MOs) that collide with a target MO for a user equipment (UE); determine, based on the number, a scaling factor to be used for an inter frequency cell identification requirement; and encode, for transmission to the UE, an indication of the scaling factor.
