Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conflict between SMTC and NCSG resource configurations leads to prolonged intra-frequency measurement periodicity and increased result reporting delays, degrading mobility handover performance in terminal devices.
Innovation Solution
Implementing intra-frequency measurement without measurement gaps by defining scaling factors for SMTC and NCSG, allowing simultaneous measurement and data transmission, thereby shortening measurement periodicity and reducing reporting delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If SMTC-based intra-frequency measurement is performed without measurement gap, then measurement periodicity is shortened and reporting delay is reduced, but resource conflict with NCSG occurs
Solution Approach 1:
The patent changes the measurement periodicity parameter from the conventional SMTC-based periodicity to a new periodicity calculated based on NCSG configuration and terminal capability. This parameter change allows the measurement to be performed without measurement gap while avoiding resource conflicts, thereby shortening measurement periodicity and reducing reporting delay
2Reliability
If measurement gap is used for intra-frequency measurement, then resource conflict is avoided, but measurement periodicity is prolonged and reporting delay increases
Solution Approach 1:
The patent extracts the measurement gap requirement from the intra-frequency measurement process. By determining that the terminal can perform intra-frequency measurement without measurement gap when SMTC opportunities are not covered by NCSG measurement periods, the solution removes the time-consuming measurement gap while maintaining resource configuration reliability
3Productivity
If SMTC and NCSG resource configurations overlap, then resource utilization efficiency is improved, but measurement accuracy may be affected
Solution Approach 1:
The patent implements a dynamic measurement approach where the terminal determines whether to perform intra-frequency measurement based on the coverage relationship between SMTC opportunities and NCSG measurement periods. When SMTC opportunities are not covered by NCSG periods, measurement is performed without gap; when covered, measurement is performed with gap. This dynamic adaptation ensures both resource utilization efficiency and measurement accuracy
Data Source
AI summary
A a measurement method and a communication apparatus to shorten an intra-frequency measurement periodicity and reduce a result reporting delay for intra-frequency measurement, thereby improving mobility handover performance of a terminal device. The method includes: the terminal device sends first capability information to a network device, and obtains resource configuration information for a first synchronization signal block measurement timing configuration (SMTC) and resource configuration information for a network controlled small gap (NCSG), where the first capability information indicates that the terminal device supports performing intra-frequency measurement without measurement gap in a measurement period of the NCSG. When a part or all of measurement opportunities of the first SMTC are covered by the measurement period of the NCSG, the terminal device may perform intra-frequency measurement without measurement gap based on a first intra-frequency measurement periodicity.
