Multi-Panel Terminal Simultaneous Service and Cell Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, terminals face challenges in performing cell measurement without interrupting service transmission due to beam conflicts, especially when no measurement gap is configured by the network device.
Innovation Solution
A terminal with multiple panels can perform cell measurement using an idle panel while transmitting a service, selecting the first panel for service transmission and the second panel for measurement, allowing simultaneous service transmission and cell measurement without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal uses the same panel for both service transmission and cell measurement, then the device complexity is reduced, but beam conflict occurs and cell measurement cannot be performed
Solution Approach 1:
The terminal divides its panels into different functional groups: one panel (first panel) is dedicated to service transmission with the serving cell, while another panel (second panel) is dedicated to cell measurement. This segmentation allows simultaneous service transmission and cell measurement without beam conflict, as each panel operates independently with its own beamforming resources.
2Measurement precision
If the terminal switches to a receive beam for cell measurement, then cell measurement can be performed, but service transmission is interrupted
Solution Approach 1:
The second panel acts as an intermediary resource that enables cell measurement without interfering with service transmission on the first panel. By using the second panel as a dedicated measurement resource, the terminal can perform beam measurements and cell searches while maintaining uninterrupted service transmission on the first panel, thus resolving the conflict between measurement accuracy and service continuity.
3Reliability
If the network device configures a measurement gap for the terminal, then cell measurement can be performed, but service transmission time is reduced
Solution Approach 1:
The terminal segments its panels to perform service transmission and cell measurement simultaneously on different panels, eliminating the need for measurement gaps. This allows service transmission to continue uninterrupted while cell measurement is performed in parallel on the second panel, thereby avoiding the time loss that would otherwise be incurred by pausing service transmission for measurements.
4Productivity
If the terminal uses multiple panels for simultaneous service transmission and cell measurement, then service transmission continuity is maintained, but device complexity increases
Solution Approach 1:
The terminal's panels are designed with multi-functionality in mind, where each panel can independently perform beamforming operations. The first panel handles service transmission while the second panel handles cell measurement, but both panels share the same underlying hardware architecture and control mechanisms. This universality allows the system to maintain service continuity through parallel operations without proportionally increasing overall device complexity.
