Non-Serving Cell Antenna Gain Reporting for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems face challenges in accurately reporting achievable antenna gains for non-serving cells due to varying UE antenna panel configurations, leading to suboptimal handover and carrier aggregation decisions.
Innovation Solution
The UE measures signal quality of non-serving cells, determines the achievable antenna gain for different beam configurations, and reports this information to the base station, allowing the network to make informed decisions on handover or carrier aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE reports antenna gain information for non-serving cells, then the network can make more informed handover and carrier aggregation decisions, but the complexity of the measurement and reporting mechanism increases
Solution Approach 1:
The patent segments the antenna gain reporting into two distinct parts: a first antenna gain for the non-serving cell and a second antenna gain for the serving cell. This segmentation allows the network to separately evaluate the potential benefits of adding a non-serving cell versus the impact on the current serving cell, thereby improving handover and carrier aggregation decisions while maintaining manageable reporting complexity through structured information organization.
Solution Approach 2:
The patent implements a feedback mechanism where the UE measures and reports antenna gain information back to the network. This feedback enables the network to make data-driven decisions about handover and carrier aggregation by comparing the first antenna gain (potential benefit) with the second antenna gain (impact on current connection), resolving the contradiction between decision accuracy and reporting complexity through intelligent information feedback.
2Productivity
If the UE determines and reports first and second antenna gains for multi-carrier connectivity, then the network can optimize carrier aggregation selection, but the information processing and reporting overhead increases
Solution Approach 1:
The patent merges the reporting of first and second antenna gains into a single measurement report message. By combining these related pieces of information into one structured report, the patent reduces the number of separate signaling transactions needed, thereby optimizing carrier aggregation decision efficiency while minimizing the actual information overhead transmitted over the air interface.
Solution Approach 2:
The patent changes the parameter representation by reporting antenna gains in a standardized format that can be efficiently processed by the network. The first and second antenna gains are reported as comparable parameters that enable direct evaluation of carrier aggregation options, improving decision efficiency while the standardized parameter format helps manage reporting overhead through compact information encoding.
