Adaptive UE Measurement Gaps for Overlapping Time Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conflict issue arises when a network device configures multiple types of measurement gaps for user equipment (UE) in a wireless communication system, leading to overlapping time-domain resources that interfere with UE capabilities for effective mobility measurements.
Innovation Solution
The UE performs adaptive processing based on its capabilities to utilize one or more measurement gaps, prioritizing gaps that align with its capabilities to minimize interference and ensure effective measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device configures multiple types of measurement gaps for the UE, then the measurement coverage and mobility management capability are improved, but the time domain resources overlap causing interference and reducing measurement precision
Solution Approach 1:
The UE autonomously determines which measurement gap to use based on its own capability (first capability for simultaneous measurement or second capability for prioritized measurement), without requiring network intervention to resolve the conflict. The UE self-selects the appropriate measurement strategy according to its hardware capabilities.
Solution Approach 2:
The measurement gap selection is dynamic and adapts to the UE's capability status. The UE can switch between different measurement strategies (using both gaps simultaneously or prioritizing one gap) based on whether it supports the first capability, allowing flexible adaptation to different operational conditions.
2Adaptability or versatility
If the UE uses both first measurement gap and second measurement gap for measurement, then the measurement coverage is improved, but the conflicting time domain resources cause interference and reduce reliability
Solution Approach 1:
The UE independently evaluates its capability to handle overlapping measurement gaps and automatically selects the appropriate measurement strategy. When the UE supports the first capability, it can reliably use both gaps simultaneously; when it doesn't support the first capability, it automatically prioritizes one gap, ensuring measurement reliability without external control.
3Measurement precision
If the UE suspends data transmission with the serving cell to perform mobility measurements, then the measurement accuracy is improved, but the communication interruption time increases reducing productivity
Solution Approach 1:
The UE performs measurements partially during the measurement gap periods when data transmission is suspended. By confining measurements to specific time intervals (measurement gaps) rather than continuous suspension, the system achieves necessary measurement accuracy while minimizing communication interruption and maintaining overall productivity.

AI summary
Provided in the present disclosure are a method for sending measurement configuration information, a method for receiving measurement configuration information, and an apparatus. The method for receiving measurement configuration information comprises: receiving measurement configuration information sent by a network device, wherein the measurement configuration information comprises a first measurement gap and a second measurement gap; and executing measurement by using at least one of the first measurement gap and the second measurement gap according to the capability of a user equipment, wherein a time-domain resource of the first measurement gap overlaps with a time-domain resource of the second measurement gap. In the method of the present disclosure, when there is a conflict between time-domain resources of a plurality of measurement gaps configured by the network device for the user equipment, the user equipment may perform adaptive processing in view of the capability of the user equipment itself, and perform measurement by using one or more measurement gaps, thereby realizing effective measurement in this measurement gap conflict scenario.
