Radio Resource Management Scaling Factor for EN-DC Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-UTRA-NR Dual Connectivity (EN-DC) wireless communications face challenges in managing radio resources effectively, particularly in scenarios involving Carrier Aggregation (CA), where Measurement Gaps (MGs) occur, leading to inefficiencies in measurement collection and processing.
Innovation Solution
The system enhances radio resource management by allowing user equipment (UE) to receive and process measurement objects (MOs) without MGs from both Primary and Secondary Nodes, applying a scaling factor to determine procedure periods and combining counts of MOs at common frequencies, ensuring seamless merging and resource allocation across different frequency ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are used to collect measurements for multiple NR measurement objects at the same frequency, then measurement completeness is improved, but resource allocation efficiency deteriorates due to interruptions and time loss
Solution Approach 1:
The patent combines multiple NR measurement objects at the same frequency into a single measurement procedure. When the UE receives a first inter-RAT NR MO without MG and a first intra-frequency NR MO without MG from different nodes (PN and SN) at the same frequency, it merges these measurements and transmits a single combined measurement report, eliminating the need for separate measurement gaps for each MO.
Solution Approach 2:
The patent applies preliminary coordination between the Primary Node (PN) and Secondary Node (SN) to configure measurement objects without measurement gaps. The nodes exchange information about configured MOs and proactively identify opportunities to combine measurements before the UE performs measurements, allowing the UE to prepare for efficient measurement collection without interrupting data reception.
2Measurement precision
If multiple measurement objects are processed separately, then measurement accuracy is improved, but measurement procedure time increases
Solution Approach 1:
The patent merges the processing of multiple NR measurement objects at the same frequency into a single measurement procedure. The UE performs one set of measurements that satisfies multiple MO requirements simultaneously, reducing the total measurement procedure time while maintaining measurement accuracy through coordinated configuration from PN and SN.
3Adaptability or versatility
If measurement objects from Primary Node and Secondary Node are handled independently, then node autonomy is maintained, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary coordination mechanism between the Primary Node (PN) and Secondary Node (SN). The nodes exchange measurement object configuration information and coordinate their MO assignments at common frequencies. This intermediary coordination layer allows autonomous nodes to work together efficiently, reducing system complexity by providing a standardized interface for collaboration while maintaining individual node autonomy.

AI summary
Some embodiments include a system, method, and computer program product for radio resource management (RRM) scaling factor enhancement without measurement gaps (MGs) in an E-UTRA-New Radio (NR) Dual Connectivity (EN-DC) network. Some embodiments include a user equipment (UE) that receives from a Primary Node (PN), a first NR measurement object (MO) without MG associated with a frequency. The UE receives from a Secondary Node (SN), a second NR MO without MG associated with the same frequency. The UE allocates resources based on a Primary Secondary Component Carrier (PSCC) and determines a scaling factor for determining a total procedure period for obtaining measurements to satisfy the first and the second NR MO without MG. Some embodiments include combining counts of NR MO without MG at a same frequency. Some embodiments include coordination between the PN and the SN so that MOs without MG at a common frequency satisfy the merging rule.
