Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical displacement of antenna panels in customer premises equipment (CPEs) leads to significant downtime, affecting radio optimization procedures like RLM, RRM, and beam management, resulting in sub-optimal selections and communication disruptions.
Innovation Solution
CPEs and network nodes exchange capability messages indicating mechanical displacement capabilities, allowing for radio optimization procedures to be adjusted with accommodated timing to mitigate erroneous measurements during displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical displacement of antenna panels is performed to optimize signal quality, then communication reliability is improved, but downtime increases causing radio optimization procedures to fail
Solution Approach 1:
The system performs radio optimization procedures before mechanical displacement occurs. The network node receives capability information indicating the CPE will perform mechanical displacement, and proactively schedules RLM, RRM, and beam management procedures before the displacement timing, ensuring measurements are taken when the antenna panel is stationary and functional.
Solution Approach 2:
The system dynamically adjusts the timing of radio optimization procedures based on the mechanical displacement schedule. The network node modifies measurement timing to account for displacement events, making the optimization process adaptive to the CPE's mechanical operation rather than following a fixed schedule.
2Productivity
If radio optimization procedures are performed during mechanical displacement, then measurement frequency is increased, but measurement accuracy decreases due to erroneous readings
Solution Approach 1:
The system extracts or removes radio optimization measurements from the time periods when mechanical displacement is occurring. By identifying displacement intervals from capability information, the network node schedules measurements only during stable periods when the antenna panel is not moving, eliminating erroneous measurements caused by displacement.
Solution Approach 2:
The system performs measurements before displacement occurs rather than during or after. By scheduling RLM, RRM, and beam management procedures in advance of known displacement events, the system ensures high-accuracy measurements are captured when the antenna configuration is stable.
3Device complexity
If mechanical displacement capability is not indicated to the network, then device complexity is reduced, but radio optimization efficiency decreases
Solution Approach 1:
The CPE provides feedback to the network node about its mechanical displacement capability through capability information messages. This feedback mechanism allows the network to understand when displacement will occur and adjust optimization procedures accordingly, improving overall system efficiency without requiring complex coordination protocols.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a customer premises equipment (CPE) may transmit a capability message that includes an indication of a mechanical displacement capability at the CPE. The CPE may receive an instruction to perform a radio optimization procedure that is based at least in part on the mechanical displacement capability, the radio optimization procedure comprising at least one of: a radio link monitoring (RLM) procedure, a radio resource management (RRM) procedure, or a beam management procedure. Numerous other aspects are described.
