UE-Requested SMTC Window Adaptation for Efficient RRM Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in radio resource management (RRM) measurements due to the UE performing RRM measurements within SMTC windows, which can lead to suboptimal use of resources as the UE may reuse SSB measurements from a burst set before the SMTC window.
Innovation Solution
A mechanism is introduced for SMTC configuration adaptation, allowing the UE to request adjustments to the SMTC configuration, enabling the skipping of SMTC window occasions and allowing more efficient use of resources for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs RRM measurements within SMTC windows, then the RRM measurements can be performed on dedicated resources, but the resources cannot be reused for data transmission and the UE cannot efficiently utilize SSB measurements from burst sets before SMTC windows
Solution Approach 1:
The patent applies dynamics by making the SMTC window configuration adaptable and changeable based on UE measurement needs. The network can dynamically adjust SMTC parameters (periodicity, offset, duration) or skip SMTC windows when the UE has sufficient measurements from burst sets, transforming the static SMTC configuration into a dynamic one that optimizes resource usage while maintaining measurement reliability.
Solution Approach 2:
The patent utilizes parameter changes by modifying SMTC configuration parameters (periodicity, offset, duration, window occasion skipping) based on the UE's measurement status and network conditions. When the UE has adequate SSB measurements from burst sets, the network can change the SMTC configuration to skip certain windows or adjust parameters, thereby improving resource utilization while maintaining reliable RRM measurements.
2Productivity
If the UE skips SMTC window occasions to improve resource utilization, then more resources become available for data transmission, but the RRM measurement coverage may be reduced
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports its measurement status and capability to the network, and the network responds by adjusting SMTC configurations accordingly. The network receives feedback about the UE's ability to perform measurements from burst sets and uses this feedback to determine whether to skip SMTC windows or maintain them, ensuring that measurement coverage is sufficient while maximizing resource utilization.
Solution Approach 2:
The patent applies self-service by enabling the UE to autonomously perform measurements from burst sets before SMTC windows, reducing the dependency on dedicated SMTC window occasions. The UE can self-manage its measurement activities by utilizing available burst set measurements, allowing the network to skip SMTC windows when measurements are sufficient, thereby improving resource efficiency without compromising measurement coverage.
