Solution Overview
Problem
The communication-calculation integrated architecture in wireless networks faces challenges in handling heterogeneous data requirements, particularly in scenarios with strict delay constraints, due to serial delays between communication and calculation processes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication and calculation are performed in parallel on different frequency bands, then delay is reduced and productivity is improved, but device complexity increases due to multi-band resource management
Solution Approach 1:
The system segments data into two types: first-type data for calculation and second-type data for communication, transmitting them on different frequency bands. This segmentation enables parallel processing while maintaining manageable system complexity through clear functional separation.
Solution Approach 2:
The patent introduces frequency band as an additional dimension for resource allocation. By utilizing different frequency bands (first frequency band for calculation, second frequency band for communication), the system achieves parallel processing without significantly increasing temporal or spatial complexity.
2Speed
If channel superposition is used for calculation, then processing speed is improved, but reliability decreases due to channel fluctuations
Solution Approach 1:
The system performs preliminary actions by transmitting second-type data (communication data) on the second frequency band before or during the calculation process. This ensures that communication requirements are met independently of channel fluctuations affecting the first frequency band, thereby maintaining reliability while achieving speed improvement through parallel processing.
Solution Approach 2:
The patent changes the frequency band parameter to separate calculation and communication processes. By allocating different frequency bands for different data types, the system can tolerate channel fluctuations on one band while maintaining reliable operation on the other, thus balancing speed and reliability.

AI summary
A wireless communication method and a communications device are provided. The method includes: receiving, by a first device, a calculation result of first-type data of one or more second devices and/or second-type data of one or more second devices, where the first-type data is to-be-calculated data, the first-type data of the one or more second devices is carried on a first frequency band, and the calculation result is determined based on channel superposition of the first frequency band; and the second-type data is non-calculation data, and the second-type data of the one or more second devices is carried on one or more second frequency bands. In the present application, in a communication-calculation integrated process, a calculation process of the to-be-calculated data and a communication process of the non-calculation data may be performed in parallel. This facilitates avoiding a serial delay between communication and calculation.
