Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous/concurrent uplink and downlink transmissions are implemented, then data transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the wireless communication channel into orthogonal resource units (time, frequency, code domains) that can be independently allocated to different users and directions (uplink/downlink). This segmentation enables simultaneous transmissions without interference while maintaining manageable protocol complexity through structured resource management.
Solution Approach 2:
The patent introduces multiple dimensions for resource allocation including time division, frequency division, and code division. By adding these dimensional layers, the system achieves full-duplex simultaneous transmissions in uplink and downlink directions without increasing baseband processing complexity, as each dimension provides independent transmission paths.
2Loss of time
If advanced resource allocation mechanisms are implemented, then latency is reduced, but device complexity increases
Solution Approach 1:
The patent implements preliminary resource allocation where resource units are pre-configured and announced to stations before actual data transmissions. This advance notification allows stations to prepare transmission buffers and synchronize timing, significantly reducing latency while keeping the allocation mechanism systematic and manageable through standardized signaling protocols.
Solution Approach 2:
The patent incorporates feedback mechanisms where reception status and channel conditions are reported back to the access point, enabling dynamic resource reallocation. This feedback loop optimizes latency by adapting to real-time network conditions while maintaining complexity through standardized feedback message formats and processing procedures.
3Use of energy by moving object
If coordinated transmission synchronization is implemented, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent implements periodic transmission opportunities and structured communication cycles where stations wake at predetermined intervals to transmit or receive data. This periodic structure allows stations to enter low-power sleep modes between active periods, significantly reducing power consumption while maintaining simple synchronization through periodic timing signals and standardized wake-up procedures.
