Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different preamble sequence formats are designed for different scenarios, then communication scenarios are covered comprehensively, but device complexity and processing complexity increase
Solution Approach 1:
The patent applies universality by enabling a single signal to serve multiple communication procedures. Specifically, the sounding reference signal is configured to function both for initial access and for uplink synchronization, eliminating the need for separate preamble sequences and SRS for different scenarios. This multi-functional approach reduces device complexity while maintaining comprehensive scenario coverage.
2Adaptability or versatility
If multiple preamble sequence formats are reserved for different scenarios, then various communication scenarios are supported, but resource utilization decreases due to resource waste
Solution Approach 1:
The patent implements universality by configuring a single sounding reference signal to perform dual functions: initial access and uplink synchronization. This eliminates the need to reserve separate PRACH resources for different scenarios, thereby supporting various communication scenarios while preventing resource waste that would otherwise occur from maintaining multiple dedicated resource pools.
3Reliability
If terminal device sends both PRACH and SRS for initial access and uplink synchronization, then communication procedures are completed accurately, but chip costs and processing complexity increase
Solution Approach 1:
The patent applies merging by combining the functions of PRACH and SRS into a single sounding reference signal transmission. The network device configures the SRS to serve both initial access and uplink synchronization purposes, merging what were previously separate signaling procedures into one unified transmission, thereby reducing chip costs and processing complexity while maintaining procedure completion accuracy.
Solution Approach 2:
The patent implements universality by enabling the sounding reference signal to perform multiple functions simultaneously - serving as both the initial access signal and the uplink synchronization signal. This multi-functional approach eliminates the need for separate PRACH and SRS transmissions, reducing terminal device complexity and chip costs while ensuring reliable completion of both communication procedures.

AI summary
In a communication method, a first communication apparatus obtains first configuration information of a first signal, where the first configuration information is associated with a first communication procedure of the first communication apparatus. The first communication apparatus obtains second configuration information of the first signal, where the second configuration information is associated with a second communication procedure of the first communication apparatus. The first communication apparatus sends the first signal based on at least one of the first configuration information or the second configuration information. In this way, the first communication apparatus can use a same type of signals to perform different communication procedures. This reduces processing complexity, and can further reduce chip costs of the first communication apparatus and improve resource utilization.
