Terminal Gap Indication for Flexible Cell Measurement Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement configuration methods in wireless communication systems, particularly with network-controlled small gaps (NCSG), are not flexible enough, leading to suboptimal utilization of terminal capabilities and prolonged data transmission interruptions during cell measurements.
Innovation Solution
Implementing an information indication method where a terminal device transmits first indication information to a network device to indicate gap-related information in various cell states, allowing the network device to configure gaps (MG and/or NCSG) more flexibly based on the terminal's capabilities and requirements, thereby optimizing data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If network-controlled small gap (NCSG) is introduced to reduce measurement interruption, then data transmission interruption time is reduced, but measurement configuration flexibility is insufficient
Solution Approach 1:
The patent applies dynamics by enabling the terminal device to dynamically indicate its measurement capability and gap requirements through first indication information. The network device can then adaptively configure different gap patterns (MG or NCSG) based on the terminal's real-time state and capabilities, making the measurement configuration flexible and dynamic rather than static and rigid.
Solution Approach 2:
The patent utilizes parameter changes by allowing the terminal device to report its measurement capability parameters (such as measurement capability indicator) and gap requirement parameters (such as gap pattern preference) to the network device. The network device adjusts gap configuration parameters based on these reported values, optimizing the balance between measurement accuracy and data transmission continuity.
2Measurement precision
If measurement is performed in measurement gap (MG) to ensure accurate cell quality measurement, then measurement accuracy is improved, but data transmission is interrupted for longer duration
Solution Approach 1:
The patent applies local quality by differentiating measurement requirements for different cell states (serving cell, neighboring cell, deactivated cell). For serving cells with continuous data transmission, the terminal indicates capability to perform measurements without full MG interruption. For neighboring cells or deactivated cells, traditional MG or NCSG is used. This localized approach optimizes measurement accuracy while minimizing interruption only where necessary.
Solution Approach 2:
The patent enables dynamic selection between MG and NCSG based on terminal capability indication and current cell state. When the terminal indicates it has measurement capability during data transmission, the network configures NCSG for shorter interruption. When measurement accuracy is prioritized or terminal capability is limited, MG is configured. This dynamic adaptation resolves the contradiction between measurement precision and interruption time.
3Duration of action of stationary object
If traditional measurement configuration is used to maintain serving cell data transmission, then data transmission continuity is maintained, but measurement capability utilization is insufficient
Solution Approach 1:
The patent implements feedback by having the terminal device report its measurement capability (first indication information) and receive network configuration (second indication information) based on this feedback. The network device uses this feedback to configure appropriate gap patterns that fully utilize the terminal's measurement capabilities while maintaining data transmission continuity, thereby improving measurement capability utilization without sacrificing transmission continuity.
