UE Measurement Gap Deactivation for Priority Data Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measurement gaps in wireless communications systems cause challenges for time-critical data transmission, such as extended reality data, as they disrupt signal transmission and reception, leading to collisions and inefficiencies.
Innovation Solution
User equipment (UE) transmits UE assistance information (UAI) to the network entity to indicate which measurement gaps can be deactivated based on collision thresholds, allowing data reception during these gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are configured for signal quality measurements, then measurement accuracy is improved, but data transmission reliability deteriorates due to collisions with time-critical data
Solution Approach 1:
The measurement gap configuration is made dynamic and adjustable. The network entity can configure different measurement gap patterns based on traffic conditions, and the UE can request adjustments when collisions with time-critical data occur. This allows the system to adapt between measurement needs and data transmission requirements in real-time.
Solution Approach 2:
The invention changes the parameters of measurement gaps (timing, duration, frequency) based on data transmission requirements. When time-critical data is detected, the measurement gap parameters are adjusted to avoid collisions, thereby maintaining data transmission reliability while still enabling measurements when appropriate.
2Adaptability or versatility
If measurement gaps are used for cell measurements, then network mobility management is improved, but communication efficiency deteriorates due to signal transmission disruption
Solution Approach 1:
Measurement gaps are implemented as periodic, scheduled intervals rather than continuous disruptions. This allows the system to maintain regular measurement routines for mobility management while minimizing impact on data transmission by confining measurements to specific periodic windows.
Solution Approach 2:
The measurement gap schedule is made dynamic, allowing the network to adjust the timing and frequency of measurement gaps based on current traffic conditions and mobility requirements, optimizing both mobility management and communication efficiency.
3Reliability
If measurement gaps are deactivated to avoid collisions, then data transmission reliability is improved, but measurement capability deteriorates
Solution Approach 1:
Rather than completely deactivating measurement capability, the system changes the parameters of measurement gaps to avoid collisions with time-critical data. This maintains measurement capability while adjusting timing to prevent disruptions to important data transmissions.
Solution Approach 2:
The UE provides feedback to the network entity about measurement gap collisions with time-critical data. This feedback mechanism allows the network to adjust measurement gap configurations to maintain both measurement capability and data transmission reliability.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) transmits an indication of one or more types of measurement gaps for which deactivation is supported based on collisions with data having a priority satisfying a threshold. The UE receives an indication of deactivation of one or more measurement gaps based on the indication of one or more types of measurement gaps. The UE receives the data during a time duration that at least partially overlaps with the one or more measurement gaps based on the indication of deactivation.
