Engineering Contradiction Analysis
1Reliability
If SMTC-based intra-frequency measurement periodicity is prolonged to avoid conflict with NCSG resource configuration, then resource conflict is resolved, but measurement reporting delay increases
Solution Approach 1:
The patent applies dynamics by making the measurement periodicity adjustable rather than fixed. The terminal device dynamically determines the intra-frequency measurement periodicity based on the conflict relationship between SMTC and NCSG resources, allowing the system to adapt the measurement timing to avoid conflicts while maintaining acceptable reporting delays. This is achieved through receiving indication information from the network device that specifies the measurement periodicity under conflict conditions.
Solution Approach 2:
The patent changes the parameter of measurement periodicity based on different conflict scenarios. When SMTC and NCSG resources conflict, the system adjusts the intra-frequency measurement periodicity parameter to resolve the conflict. The network device provides indication information that modifies this parameter, allowing the terminal to perform measurements at adjusted intervals that avoid resource conflicts while minimizing impact on handover performance.
2Measurement precision
If measurement gap is used for inter-frequency RRM measurement, then measurement accuracy is improved, but data transmission is blocked during measurement period
Solution Approach 1:
The patent applies segmentation by separating intra-frequency and inter-frequency measurement resources in the time domain. Intra-frequency measurements using SMTC are scheduled during specific measurement opportunities that do not overlap with NCSG measurement periods. This segmentation allows the terminal to perform intra-frequency measurements without requiring measurement gaps, thereby maintaining data transmission continuity while still achieving accurate RRM measurements for handover decisions.
Solution Approach 2:
The patent ensures continuity of useful action by enabling data transmission to continue during NCSG measurement periods. By configuring intra-frequency measurements to occur outside of NCSG measurement gaps, the system maintains uninterrupted data transmission for active services. The terminal can simultaneously maintain connectivity and perform necessary measurements without blocking data flow, thus preserving productivity while achieving measurement objectives.

AI summary
This application provides 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. The first intra-frequency measurement periodicity is determined based on at least a periodicity of the first SMTC, a first scaling factor, and a second scaling factor, and the first scaling factor and the second scaling factor are 1.
