Engineering Contradiction Analysis
1Productivity
If full-duplex wireless communication is implemented by simultaneously transmitting and receiving signals on the same radio channel, then spectrum utilization is doubled, but mutual interference between signal sending and receiving occurs
Solution Approach 1:
The patent divides the coverage area into multiple transmit sectors and receive sectors, creating separate spatial channels for transmission and reception. This segmentation allows simultaneous full-duplex operation while reducing mutual interference through spatial isolation between transmit and receive beams.
Solution Approach 2:
The patent introduces spatial dimension through sectorization, moving from a single omnidirectional channel to multiple directional beams. By utilizing the spatial dimension, the system achieves frequency reuse and isolation, enabling full-duplex communication with reduced interference.
2Reliability
If paired stations are configured for full-duplex communication, then communication quality can be improved, but complex configuration and pairing management is required
Solution Approach 1:
The patent performs beam training for all transmit sectors and receive sectors to identify optimal paired stations, rather than attempting to manage all possible pairings. This partial action approach focuses resources on finding the best pairs, simplifying configuration while maintaining high communication quality.
Solution Approach 2:
The patent implements feedback mechanisms where receiving stations report back to transmitting stations about signal quality and sector performance. This feedback enables automatic pairing optimization, reducing manual configuration complexity while improving communication quality through data-driven decisions.
3Productivity
If beam training is performed for each sector to identify optimal paired stations, then signal transmission efficiency is improved, but additional signaling overhead and time consumption occurs
Solution Approach 1:
The patent performs beam training in advance to pre-identify optimal paired stations and their corresponding sector combinations. This preliminary action stores pairing information for future use, reducing the need for repeated beam training and minimizing time loss during actual data transmission.
Solution Approach 2:
The patent combines beam training procedures with existing connection establishment protocols, merging multiple functions into a single integrated process. This reduces the overall time overhead by eliminating separate training phases and leveraging existing signaling infrastructure.
