Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of radio resource management (RRM) measurements increases when user equipment (UE) is configured with multiple concurrent measurement gap patterns (MGPs), leading to challenges in efficiently performing independent measurements on multiple carrier frequencies.
Innovation Solution
The UE links measurement resources on carrier frequencies with specific measurement gap patterns (MGPs) using configuration parameters, allowing independent RRM measurements by associating each resource with a unique MGP, ensuring non-overlapping measurement intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE is configured with multiple concurrent measurement gap patterns (MGPs) to perform independent measurements on multiple carrier frequencies, then the measurement precision and positional awareness are improved, but the device complexity and difficulty of managing measurement intervals increase
Solution Approach 1:
The patent segments the measurement management by introducing separate configuration parameters for each MGP (first MGP configuration parameters, second MGP configuration parameters) and explicitly associating each carrier frequency with a specific MGP. This segmentation allows the UE to independently manage measurement intervals for different frequency ranges without interference, reducing the overall complexity of handling multiple concurrent measurements.
Solution Approach 2:
The patent adds a new dimension of management by introducing explicit linkage information that associates measurement resources on each carrier frequency with a specific MGP. This dimensional addition (the association layer) provides a clear mapping relationship that simplifies the management of multiple concurrent MGPs, allowing the UE to systematically organize measurements across different frequency ranges and time intervals.
2Reliability
If the network configures the UE with multiple concurrent MGPs to enhance radio link accuracy and positional awareness, then the reliability of RRM measurements is improved, but the ease of operation and configuration complexity increase
Solution Approach 1:
The patent applies preliminary action by having the network pre-configure multiple concurrent MGPs with their respective configuration parameters before the UE performs measurements. The association between carrier frequencies and specific MGPs is established in advance through configuration messages, allowing the UE to seamlessly switch between different measurement patterns without real-time decision complexity, thus maintaining ease of operation while ensuring reliable measurements.
Solution Approach 2:
The patent introduces an intermediary layer of configuration parameters that mediate between the network's measurement requirements and the UE's execution. The first and second MGP configuration parameters act as intermediaries, providing a structured interface that simplifies the configuration process while enabling complex multi-frequency measurement operations with high reliability.
3Productivity
If the UE performs independent measurements on multiple carrier frequencies using multiple concurrent MGPs, then the productivity of RRM assessment is improved, but the loss of time for coordinating measurement intervals increases
Solution Approach 1:
The patent applies local quality by allowing different measurement gap patterns to be optimized for different carrier frequencies based on their specific requirements. Each MGP can have customized time intervals and resource configurations tailored to the characteristics of the associated frequency range, enabling efficient local measurements without requiring a uniform measurement approach across all frequencies, thus reducing overall coordination time.
Data Source
AI summary
Methods and systems are disclosed for a UE to perform measurements of measurement resources transmitted by a network when the UE is configured with multiple concurrent measurement gap patterns (MGPs). The measurement resources may be carried on multiple carrier frequencies. The UE may receive measurement resource configuration parameters identifying time and frequency locations of the measurement resources transmitted on the multiple carrier frequencies. The UE may receive measurement gap configuration parameters for multiple concurrent MGPs specifying measurement intervals that may be used to perform the measurements. The UE may determine a linkage between the measurement resources on a carrier frequency and one of the concurrent MGPs so that the UE may independently measure the measurement resources received on the multiple carrier frequencies using their respectively linked MGPs. The linkage may be made through information elements in the measurement resource configuration parameters or the measurement gap configuration parameters containing the MGP.
