Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple active bandwidth parts are used for full-duplex communication, then spectrum efficiency and data rate are improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent divides the communication resources into multiple active bandwidth parts (BWPs), each handling specific frequency ranges and communication directions. This segmentation allows independent management of each BWP, reducing overall system complexity while enabling full-duplex operation across multiple frequency bands simultaneously
Solution Approach 2:
The patent implements a unified scheduling mechanism that can allocate resources across multiple active BWPs using a single downlink control information (DCI) message. This multi-functional approach allows one scheduling system to manage multiple BWPs, reducing the need for separate control channels and simplifying resource management
2Productivity
If multiple active bandwidth parts are configured, then communication capacity increases, but latency in resource allocation and switching increases
Solution Approach 1:
The patent pre-configures multiple active BWPs with their respective parameters and characteristics before communication begins. This preliminary setup allows the system to immediately utilize all configured BWPs without runtime configuration delays, reducing latency while maintaining high communication capacity
Solution Approach 2:
The patent combines resource allocation information for multiple BWPs into a single DCI message structure. This merging eliminates the need for separate scheduling messages for each BWP, reducing control overhead and latency while maintaining the ability to allocate resources across all active bandwidth parts simultaneously
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves spectrum efficiency and reduces latency by enabling simultaneous communication across multiple BWPs, optimizing resource allocation and switching times.
Implementation Method 1
Beamforming is a signal processing technique used with an antenna array for directional signal transmission and/or reception. Each antenna in the antenna array transmits a signal that is combined with other signals of other antennas of the same array in such a way that signals at particular angles experience constructive interference while others experience destructive interference.
Implementation Method 2
In the case of FD using spatial multiplexing, different antenna arrays (e.g., different antenna panels) and beams are operable at the same time but still can achieve FD simultaneous communication through spatial separation (e.g., such as through beam direction).

AI summary
Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment (UE) with two or more active BWPs. In some examples, the base station may send scheduling information to the UE on one active BWP, where the scheduling information schedules a communication on one or more active BWPs.
