Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face limitations in efficiently configuring and managing multiple measurement gaps, particularly in 5G and beyond, which restrict UE performance and network flexibility.
Innovation Solution
A method and wireless network are developed to support multiple measurement gaps through RRC messages with additional IEs for gap configuration, allowing activation, deactivation, and release of preconfigured gaps, including network-controlled small gaps, using MAC CE and DCI signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single measurement gap configuration is used in existing wireless systems, then the system structure remains simple, but the network cannot efficiently support multiple concurrent measurement tasks and diverse measurement scenarios
Solution Approach 1:
The patent divides the measurement gap configuration into multiple independent gap configurations, each with its own identifier (gapID), time resources, and associated measurement objects. This segmentation allows the network to configure multiple measurement gaps simultaneously for different measurement tasks, resolving the contradiction between versatility and complexity by managing each gap as a separate configurable entity through the RRC message structure with multiple GapConfig information elements.
2Productivity
If multiple measurement gaps are configured concurrently, then the network can support diverse measurement scenarios and improve UE performance, but the configuration and management complexity increases significantly
Solution Approach 1:
The patent introduces dynamic activation and deactivation mechanisms for measurement gaps through the activationStatus field in each GapConfig. The network can dynamically activate or deactivate specific measurement gaps based on current measurement requirements, and can release gaps when no longer needed. This dynamic management allows the system to maintain multiple gap configurations but only activate the necessary ones, improving productivity while controlling complexity through selective activation rather than permanent configuration of all possible gaps.
Solution Approach 2:
The patent implements preconfiguration of measurement gaps where the network can configure multiple measurement gap parameters in advance through RRC messages, storing them with different gapID identifiers. These preconfigured gaps can then be quickly activated or deactivated based on measurement needs without requiring full reconfiguration. This preliminary action prepares the system for diverse measurement scenarios while managing complexity by having gaps ready but not necessarily all active simultaneously.
3Adaptability or versatility
If additional Information Elements are added to RRC messages for multiple gap configuration, then the network gains fine-grained control over measurement gaps, but the message size and processing overhead increase
Solution Approach 1:
The patent creates a universal GapConfig information element structure that can be repeated multiple times within the RRC message, each instance containing all necessary parameters (gapOffset, mgl, mgrp, mgta, measObjectList, activationStatus, releaseList) for a complete measurement gap configuration. This multi-functional structure allows the same information element template to configure any number of measurement gaps with different parameters, providing fine-grained control while avoiding the need for separate specialized message types for each gap, thus managing message size through template reuse.

AI summary
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method for supporting multiple measurement gaps in a wireless network by a radio access network node (RAN node) is provided. The method includes creating a radio resource control (RRC) message comprising one of a RRC Reconfiguration or a RRC Resume with additional Information Elements (IEs) for configuration of the multiple measurement gaps, transmitting the RRC message with the additional IEs in the gap configuration of each of the measurement gap to a user equipment (UE) in the wireless network for configuration of the multiple measurement gaps. Further, the method includes receiving an RRC message comprising of one of an RRC Reconfiguration Complete or an RRC Resume Complete indicating successful application of the received measurement gap configuration from the UE.
