Antenna Panel Power Management for 5G V2X Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, particularly in V2X technology, unused antenna panels on vehicles remain powered on, leading to increased power consumption without contributing to signal transmission or reception, as they are not utilized in directional beam formation.
Innovation Solution
A method for a communication device to transmit capability information to a base station, receive measurement configuration, power on/off unused antenna panels based on movement speed or communication mode, and report the power state and measurement results to optimize power usage by turning off unused panels during low-speed movements or in broadcast modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all antenna panels are kept in power-on state, then signal reception capability is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic power management for antenna panels by transitioning between power-on and power-off states based on operational conditions. The communication device determines whether to power on unused antenna panels during measurement operations, creating a dynamic adaptation mechanism that balances signal reception capability with power consumption requirements
2Use of energy by moving object
If unused antenna panels are powered off, then power consumption is reduced, but measurement capability is degraded
Solution Approach 1:
The patent applies preliminary action by powering on the antenna panel before measurement operations are needed. The device determines in advance that the antenna panel should be powered on for measurement, performs the measurement operation, and then may power it off again. This ensures measurement capability is available when required while minimizing power consumption during non-measurement periods
3Productivity
If all antenna panels remain powered on, then measurement operations can be performed随时, but energy is wasted
Solution Approach 1:
The patent implements periodic action through measurement operations that are triggered at specific times or under specific conditions rather than continuously. The antenna panel is powered on for measurement operations and may be powered off between measurements, creating a periodic operational pattern that maintains measurement availability when needed while reducing energy waste during idle periods

AI summary
One disclosure of the present specification provides a method by which a communication device, which performs a measurement through multiple antenna panels, reports the measurement. The method may include the steps of: transmitting capability information to a base station; receiving measurement setting information from the base station; powering on a powered-off antenna panel among the multiple antennal panels in order to perform a measurement; performing the measurement through the multiple antenna panels; and transmitting a measurement report message including information indicating whether the corresponding antenna panel was in a powered-on state or a powered-off state prior to the measurement, and information on the measurement result.
