Antenna Panel Activation by Sleep Duration for Beam Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-frequency wireless communications networks, terminals equipped with multiple antenna panels face challenges in efficiently selecting suitable panels and beams for communication with base stations during discontinuous reception, leading to increased power consumption and potential loss of beam alignment due to movement, rotation, or channel changes.
Innovation Solution
The method involves activating a single panel if sleep duration is less than a threshold and multiple panels if the duration is greater than or equal to the threshold, with beam training conducted using pre-delivered beam management resources to quickly find a suitable beam for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna panels are activated to cover different directions, then beam alignment reliability is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the number of activated antenna panels based on sleep duration. For short sleep durations, only one panel is activated to save power. For long sleep durations, multiple panels are activated to ensure reliable beam alignment, as the terminal may have moved or rotated during the extended sleep period.
Solution Approach 2:
The patent changes the operational state parameter of antenna panels based on sleep duration thresholds. The network device configures different quantities of panels to be activated according to whether the sleep duration is short or long, optimizing the balance between power consumption and communication reliability.
2Reliability
If multiple panels are activated after long sleep duration, then beam alignment is maintained, but power consumption increases
Solution Approach 1:
The system dynamically determines the number of panels to activate based on sleep duration. After long sleep durations, multiple panels are activated to account for potential terminal movement or rotation that may have occurred during the extended period, ensuring beam alignment is maintained despite the increased power consumption.
3Use of energy by moving object
If a single panel is activated for short sleep duration, then power consumption is reduced, but beam alignment may be lost due to movement or rotation
Solution Approach 1:
The patent implements dynamic panel activation strategy where the number of activated panels adapts to sleep duration. For short sleep durations, only one panel is activated to minimize power consumption, as the terminal is less likely to have changed position significantly.
Solution Approach 2:
The network device pre-configures different quantities of panels to be activated based on anticipated sleep durations. This preliminary configuration allows the terminal to efficiently manage power consumption while maintaining adequate beam alignment coverage for different sleep scenarios.
4Reliability
If all panels are activated to ensure communication coverage, then communication reliability is improved, but power consumption and device complexity increase
Solution Approach 1:
The patent employs dynamic panel activation where the quantity of activated panels is adjusted based on sleep duration. This dynamic approach ensures communication reliability is maintained when needed (long sleep durations) while reducing power consumption and simplifying panel management during short sleep durations.
Solution Approach 2:
The system changes the activation state parameter of antenna panels based on sleep duration thresholds. The network device configures different quantities of panels to be activated, allowing the terminal to manage panel complexity efficiently while maintaining communication reliability across different operational scenarios.

AI summary
This application provides an antenna panel management method of a terminal device. The method includes: The terminal device enters a sleep mode from an active mode. When the terminal device is ready to re-enter the active mode from the sleep mode, if sleep duration is less than a preset threshold, a single panel panel of the terminal device is activated; or if sleep duration is greater than or equal to a preset threshold, a plurality of panels of the terminal device are activated. The terminal device activates a panel based on sleep duration between two consecutive DRX ON modes, so that a suitable panel can be activated in time, and a suitable beam can be further found for communication with a base station, thereby reducing power consumption of the terminal device.
