Aggregating Measurement Gap Occasions for Wireless Channel Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in scheduling diverse channel measurements within a single measurement gap occasion, leading to potential delays or incomplete measurements due to overlapping or non-overlapping measurement gap occasions.
Innovation Solution
The implementation of multiple measurement gap occasions allows user equipment (UE) to aggregate or cancel gap occasions, creating an aggregate measurement gap occasion with configurable interruption durations, enabling flexible channel measurements that can absorb spacing or overlap, thereby improving reliability and reducing latency.

Engineering Contradiction Analysis
1Reliability
If multiple measurement gap occasions are used to perform diverse channel measurements, then measurement flexibility and reliability are improved, but measurement gap configuration complexity and device complexity increase
Solution Approach 1:
The patent segments measurement gap occasions into multiple individual gap occasions, each with its own configuration parameters (duration, periodicity, offset). This allows the UE to selectively aggregate specific gap occasions based on measurement requirements, improving reliability through multiple measurement opportunities while managing complexity through modular configuration of each segment.
Solution Approach 2:
The patent introduces dynamic aggregation where the UE can adaptively combine multiple measurement gap occasions based on real-time measurement needs, RF retuning requirements, and network configuration. The aggregation behavior is flexible and can be adjusted through UE capability signaling and network control, allowing the system to optimize between reliability and complexity dynamically.
2Reliability
If measurement gap occasions are aggregated to create longer measurement periods, then measurement completeness is improved, but measurement latency increases
Solution Approach 1:
The patent applies partial aggregation by selecting only the necessary subset of measurement gap occasions to aggregate, rather than aggregating all available gaps. The UE can choose to aggregate 2, 3, or more gap occasions based on specific measurement requirements, achieving sufficient measurement completeness while minimizing the time loss associated with longer aggregated periods.
Solution Approach 2:
The patent enables dynamic adjustment of measurement gap parameters including duration, periodicity, and aggregation level. By changing these parameters based on measurement needs, the system can optimize the balance between measurement completeness (requiring longer/aggregated gaps) and measurement latency (requiring shorter/more frequent gaps).
3Reliability
If measurement interruption durations are configured at beginning and ending of aggregate gap occasion, then RF retuning reliability is improved, but available measurement time is reduced
Solution Approach 1:
The patent configures measurement interruption durations at the beginning and ending of aggregate measurement gap occasions to account for RF retuning and reconfiguration activities. This preliminary action ensures that the RF chain is properly tuned before measurements start and reconfigured after measurements complete, improving measurement reliability while the system optimizes the overall gap duration to minimize impact on available measurement time.

AI summary
Techniques for wireless communication at a communication device are described. The communication device may be a user equipment (UE) configured to transmit, to a base station, signaling indicating UE capability information. The UE may receive, from the base station, control signaling indicating a measurement gap sequence configuration based on the UE capability information. The UE may determine a measurement gap occasion based on the measurement gap sequence configuration. The measurement gap occasion may include one or more of a first measurement gap occasion associated with a first measurement gap sequence, a second measurement gap occasion associated with a second measurement gap sequence, or a combination of the first measurement gap occasion and the second measurement gap occasion. The UE may perform a set of channel measurements during the determined measurement gap occasion.
