Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uplink MU-MIMO procedures are implemented using existing methods, then uplink multiple access capability is improved, but control information exchange complexity increases
Solution Approach 1:
The patent extracts the base station from the control information exchange process by enabling terminal devices to autonomously perform resource securing through autonomous decentralized control. This removes the need for the base station to comprehend and manage detailed data traffic information of each terminal, thereby reducing control information exchange complexity while maintaining uplink multiple access capability
Solution Approach 2:
Terminal devices are empowered with autonomous decentralized control units that enable them to self-manage resource securing without requiring complex base station coordination. Each terminal device independently determines resource securing based on locally generated contention windows and received connection information, eliminating the need for extensive control information exchange with the base station
2Measurement precision
If base station comprehends data traffic information of each terminal device, then resource allocation accuracy is improved, but network complexity increases
Solution Approach 1:
Each terminal device is equipped with an autonomous decentralized control unit that independently manages resource securing decisions. The control unit generates contention windows and determines resource securing autonomously based on locally available information, eliminating the need for the base station to comprehend detailed data traffic information of each terminal device
Solution Approach 2:
The resource allocation function is segmented from the base station and distributed to individual terminal devices. Each terminal device's autonomous decentralized control unit handles its own resource securing independently, breaking down the centralized control complexity into multiple autonomous units that operate without requiring comprehensive base station knowledge

AI summary
A method that carries out uplink multiple access while reducing complexity in processing accompanying exchange of control information. A terminal device that performs uplink multiple access communication includes a reception unit that receives a frame including uplink multiple access connection information, a first autonomous decentralized control unit that instructs securing time of a wireless resource, and a second autonomous decentralized control unit that instructs securing time of a wireless resource after reception of a frame including the uplink multiple access connection information. The terminal device is instructed securing time of the wireless resource by the first autonomous decentralized control unit in a case that a frame including the uplink multiple access connection information is not received. Securing time of the wireless resource is instructed by the second autonomous decentralized control unit in a case that a frame including the uplink multiple access connection information is received.
