Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LTE system uses a fixed triggering method for aperiodic SRS transmission, then the system can maintain simple and standardized triggering procedures, but the method cannot be applied to communication systems with multiple different signal parameters such as multiple subcarrier spacings
Solution Approach 1:
The triggering method is designed to work across multiple signal parameter configurations by using a unified triggering mechanism that can adapt to different subcarrier spacings and frequency bands. The network side generates trigger signaling that specifies frequency band and time domain location, allowing the same triggering approach to serve multiple functions across varied system configurations
Solution Approach 2:
The triggering method introduces dynamic adaptability by allowing the trigger signaling to carry flexible parameters including frequency band identification and time domain location information. This enables the triggering mechanism to dynamically adjust to different signal parameter configurations without requiring separate fixed methods for each configuration
2Reliability
If the network side generates separate triggering methods for each frequency band and signal parameter configuration, then the triggering can be optimized for each specific configuration, but the overall system complexity increases significantly
Solution Approach 1:
A single unified triggering method is designed to handle multiple frequency bands and signal parameter configurations. The trigger signaling includes parameters that allow it to specify which frequency band and time domain location should be used, making one triggering method universally applicable across different configurations without requiring separate methods for each band
Solution Approach 2:
While maintaining a unified triggering framework, the method allows for local optimization by including frequency band and time domain location parameters in the trigger signaling. This enables specific triggering behavior to be configured for each frequency band and signal parameter combination within the overall unified structure, achieving both universality and local optimization

AI summary
A triggering method and a transmitting method for an uplink reference signal in a communication system, apparatuses thereof, and a storage medium are provided. The communication system includes at least two different signal parameters. The triggering method applied to a network side includes: generating, by the network side, a trigger signaling for triggering a terminal to transmit the uplink reference signal to the network side for one or more times; and transmitting, by the network side, the trigger signaling to the terminal.
