Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If network energy saving is implemented by reducing transmission power, then energy consumption is reduced, but measurement reliability deteriorates
Solution Approach 1:
The patent applies dynamics by making the reference signal power adjustable and adaptive rather than fixed. The network can dynamically select different power values for reference signals based on current network conditions, allowing the system to optimize between energy saving and measurement reliability requirements
Solution Approach 2:
The patent changes the power parameter of reference signals by introducing multiple power values that can be selected based on different scenarios. This parameter change enables the system to reduce power consumption when measurement reliability is not critical, while maintaining sufficient power when measurement accuracy is required
2Loss of energy
If reference signal power is reduced for energy saving, then energy consumption decreases, but transmission reliability deteriorates
Solution Approach 1:
The patent makes reference signal power dynamic by allowing the network to select from multiple power values based on actual transmission conditions. This enables the system to reduce power consumption during normal conditions while maintaining reliability during critical transmission periods
Solution Approach 2:
The patent introduces multiple power parameter options for reference signals, allowing the system to change the power level based on the specific transmission scenario. This parameter flexibility resolves the contradiction between energy saving and transmission reliability
3Adaptability or versatility
If multiple power values are configured for reference signals, then adaptability to different scenarios improves, but device complexity increases
Solution Approach 1:
The patent segments the power configuration into different categories or levels, where each segment corresponds to a specific power value suitable for particular scenarios. This segmentation makes the complex multi-power system more manageable and easier to implement
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple power values and their corresponding scenarios before actual transmission occurs. The network can then directly select the appropriate pre-configured power value based on the current scenario, avoiding complex real-time calculations

AI summary
The present application discloses a method and apparatus used in a node for wireless communication. A first node receives first signaling and second signaling, the first signaling being RRC signaling, and being used for configuring at least one power offset value for a first RS resource, and the second signaling being MAC layer signaling or physical layer signaling, and being used for indicating a first power offset value for the first RS resource; a first RS is received in the first RS resource. The first power offset value simultaneously depends on the at least one power offset value and the second signaling. The ratio of the EPRE of the first RS to the EPRE of a broadcast signal is equal to the first power offset value. The broadcast signal comprises a synchronization signal. The present application improves the determination of the reference signal power in a network energy-saving scene, thereby saving the energy, and improving the measurement precision and the transmission reliability.
