Engineering Contradiction Analysis
1Productivity
If spatial reuse link transmission is performed concurrently with primary link, then network capacity and throughput are improved, but interference between links increases and transmission quality deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmit power levels and clear channel assessment thresholds based on received spatial reuse parameters. The communications node modifies transmission parameters to enable concurrent spatial reuse links while maintaining acceptable interference levels, thus improving network capacity without severely compromising transmission quality
Solution Approach 2:
The patent implements dynamics by enabling adaptive spatial reuse where transmission parameters are continuously adjusted based on real-time channel conditions and received SRPs. The system dynamically determines whether to permit spatial reuse link transmission by evaluating current interference conditions against configured thresholds, allowing the network to adaptively balance capacity and quality
2Reliability
If spatial reuse parameters are received and processed to determine transmission opportunities, then transmission quality is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring clear channel assessment thresholds and spatial reuse parameter ranges before actual transmission decisions are made. The communications node receives and stores SRPs and threshold values in advance, preparing the determination mechanism so that real-time transmission decisions can be made with simpler logic, reducing operational complexity while maintaining quality
Solution Approach 2:
The patent uses intermediary elements such as pre-configured threshold values and standardized SRP formats that mediate between raw channel measurements and transmission decisions. These intermediaries simplify the determination process by providing reference points and structured data formats, reducing the complexity of the decision-making mechanism while ensuring reliable transmission quality assessment

AI summary
Embodiments of the present invention provide a data transmission method and an apparatus. In the method, the communications node receives N spatial reuse parameters SRPs; the communications node determines, based on the received N SRPs, that the communications node can perform spatial reuse link transmission; and the communications node transmits data by using a spatial reuse link, and processes data transmission based on the spatial reuse link. Whether spatial reuse link transmission can be performed is determined based on the received SRPs, so as to reduce mutual interference between a primary link and the spatial reuse link during data transmission, and improve transmission quality.
