Measurement Configuration Signaling for Gapless Inter-System UE Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, performing inter-system measurements using measurement gaps results in suspension of communication with the serving cell, leading to service processing performance loss.
Innovation Solution
A method for transmitting measurement configuration information where a UE sends its capability to perform inter-system measurements without gaps, and a network device determines and sends corresponding indication information to allow or disallow such measurements based on the UE's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gap is used for inter-system measurement, then measurement capability is ensured, but communication with serving cell is suspended causing service processing performance loss
Solution Approach 1:
The patent changes the parameter of measurement configuration by introducing capability indication information that allows the UE to perform inter-system measurement without measurement gap when the frequency range of the to-be-measured cell is within the active bandwidth part. This parameter change resolves the contradiction by enabling measurement without suspension under specific frequency conditions.
Solution Approach 2:
The patent implements dynamic measurement gap configuration where the network device determines whether to configure measurement gap based on the UE's capability indication and the frequency range relationship. When the frequency ranges overlap, measurement gap is not configured, allowing continuous communication. This dynamic approach resolves the contradiction by adapting the measurement method to the specific frequency scenario.
2Reliability
If measurement gap is configured, then inter-system measurement can be performed, but communication continuity with serving cell is interrupted
Solution Approach 1:
The patent introduces capability indication information as a new parameter that determines the measurement configuration mode. When the indication shows the UE supports gapless measurement and frequency ranges overlap, the system switches to gapless measurement mode, maintaining communication continuity while ensuring measurement reliability through capability-based configuration.
Solution Approach 2:
The patent performs preliminary capability indication from the UE side before actual measurement configuration. The network device uses this advance information to determine the appropriate measurement configuration, preventing communication interruption before it occurs. This preliminary action resolves the contradiction by preparing the measurement mode in advance based on UE capabilities.
3Measurement precision
If UE suspends communication for measurement, then inter-system measurement is performed, but service processing performance is degraded
Solution Approach 1:
The patent changes the measurement execution parameter by enabling gapless measurement when frequency ranges overlap. The UE adjusts its RF receiver frequency without suspending communication, maintaining service processing performance while achieving inter-frequency measurement accuracy through continuous monitoring capability.
Solution Approach 2:
The patent ensures continuous communication action by eliminating measurement gap suspension. The UE performs inter-frequency measurement during normal communication operation when frequency ranges allow, maintaining uninterrupted service processing while achieving measurement objectives through continuous RF operation.
