UE Cell Measurement Report Biasing for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in maintaining service continuity during connected mode mobility, as user equipment (UE) often gets redirected to non-preferred cells, leading to reduced performance and quality of service due to unsupported features in neighboring cells.
Innovation Solution
The UE performs cell measurements and generates a biased cell measurement report to prioritize preferred cells over non-preferred cells, ensuring handover or redirection to cells that support UE-preferred features, thereby maintaining or improving service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs measurement reporting based solely on measurement criteria without considering cell preference, then the handover procedure is simple and fast, but the UE may be redirected to non-preferred cells resulting in reduced service quality
Solution Approach 1:
The patent applies local quality by differentiating between preferred and non-preferred cells in the measurement report. The UE identifies cells based on their characteristics (preferred vs non-preferred) and treats them differently in the reporting process, ensuring that preferred cells are prioritized for handover decisions while maintaining measurement accuracy.
Solution Approach 2:
The patent implements preliminary action by having the UE determine cell preference status before generating the measurement report. The UE pre-identifies which cells are preferred based on stored information about cell characteristics, and this determination is reflected in the measurement report generation process, ensuring that handover decisions are made with preference information already incorporated.
2Reliability
If the UE prioritizes preferred cells in measurement reports, then service quality and reliability improve, but the complexity of cell measurement and report generation increases
Solution Approach 1:
The patent applies preliminary action by having the UE determine cell preference status before generating the measurement report. The UE pre-identifies which cells are preferred based on stored information about cell characteristics, and this determination is reflected in the measurement report generation process, ensuring that handover decisions are made with preference information already incorporated.

3Productivity
If the UE camps on non-preferred cells during mobility, then the handover process is simpler and faster, but power efficiency and battery life are reduced

AI summary
Methods, systems, and devices for wireless communication are described. A user equipment. UE (115-a), may perform a cell measurement for at least some of a set of cells while operating in a connected mode. The UE may determine a subset of cells of the set of cells based on one or more of the cell measurement, cell-specific information (210), or UE-preferred cell information (215). The cell-specific information may include one or more respective cell parameters associated with at least some if not each cell of the subset of cells. The UE-preferred cell information may include one or more respective preferred cell parameters. The UE may transmit a cell measurement report (205) including an indication of one or more cells of the subset of cells based on the one or more cells of the subset of cells satisfying one or more cell measurement report criteria.
