XR Data Transmission During RRM Measurement Gap Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in performing radio resource management (RRM) measurements due to measurement gaps, which disrupt data transmission and reception, leading to interference and delayed frame arrivals.
Innovation Solution
Implementing a method to skip, cancel, or deactivate measurement gap occasions based on priority, allowing uninterrupted data transmission and reception by prioritizing higher-priority measurements during overlapping gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gaps are performed for RRM measurements, then measurement accuracy is improved, but data transmission efficiency deteriorates due to interruptions and frame delays
Solution Approach 1:
The patent implements dynamic adjustment of measurement gap configurations based on traffic conditions and measurement requirements. The network can adaptively modify gap patterns, durations, and frequencies to balance measurement accuracy with data transmission needs, allowing the system to transition between measurement-intensive and transmission-intensive modes as conditions change
Solution Approach 2:
The patent enables continuous data transmission during measurement gaps by allowing frames scheduled in gap periods to be transmitted and received without interruption. This maintains the continuity of useful action (data transmission) even when measurement activities are occurring, eliminating traditional gaps in communication flow
2Reliability
If measurement gaps are inserted for RRM measurements, then measurement reliability is improved, but transmission timing stability deteriorates due to frame arrival delays
Solution Approach 1:
The network performs preliminary scheduling of data frames around measurement gap occasions, anticipating when gaps will occur and adjusting transmission timing in advance. This preliminary action prevents timing disruptions by ensuring frames are scheduled to arrive during non-gap periods, maintaining timing stability while preserving measurement reliability
3Measurement precision
If measurement gaps are performed frequently, then measurement precision is improved, but system complexity increases due to gap management overhead
Solution Approach 1:
The patent employs parameter changes in measurement gap configurations, adjusting gap duration, repetition period, and offset values based on measurement requirements and traffic conditions. By dynamically modifying these parameters, the system achieves high measurement precision without requiring overly frequent or complex gap patterns, thereby managing system complexity

AI summary
A wireless device receives, from a base station, a plurality of downlink control information (DCI) comprising a first DCI and a second DCI. The first DCI indicates the wireless device to cancel a measurement gap (MG) occasion for a radio resource management (RRM) measurement. The second DCI indicates the wireless device to perform the RRM measurement during the MG occasion. In response to the receiving of the second DCI being later than the receiving of the first DCI, the wireless device performs, based on the second DCI, the RRM measurement during the MG occasion.
