Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BWP switching is performed frequently to adapt to changing data traffic types and service requirements, then adaptability and QoS are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent changes the parameter of BWP configuration by dynamically adjusting bandwidth part settings based on data traffic types and service requirements. The network device modifies BWP parameters (such as bandwidth size, subcarrier spacing, cyclic prefix length) to match different service characteristics, thereby improving adaptability without requiring complete system reconfiguration.
Solution Approach 2:
The patent implements dynamic BWP switching where the network device can switch communication devices between different BWPs in real-time based on changing traffic conditions. This dynamic adjustment allows the system to adapt to varying service requirements while maintaining manageable complexity through centralized control and predefined switching criteria.
2Productivity
If BWP switching is performed to optimize communication rate for different data traffic types, then productivity is improved, but use of energy increases due to switching operations
Solution Approach 1:
The patent adjusts BWP parameters dynamically to match data traffic characteristics. For high-rate data traffic, the system switches to BWPs with larger bandwidth and appropriate subcarrier spacing to maximize communication rate. For low-rate traffic, it switches to smaller BWPs to reduce power consumption, thereby optimizing the balance between productivity and energy usage.
Solution Approach 2:
The patent applies partial BWP switching only when necessary to meet service requirements. Instead of continuously switching BWPs, the system performs switching only when traffic conditions change significantly, avoiding unnecessary switching operations that would consume additional power while still maintaining adequate communication rates.
3Productivity
If BWP switching is performed to optimize resource utilization, then productivity is improved, but loss of time occurs due to switching delays
Solution Approach 1:
The patent prepares multiple BWP configurations in advance for different service types and traffic conditions. The network device pre-configures appropriate BWPs so that when switching is needed, the device can quickly transition to a pre-prepared configuration rather than creating a new configuration from scratch, thereby reducing switching time delays.
Solution Approach 2:
The patent implements feedback mechanisms where the network device monitors traffic conditions and proactively switches BWPs before performance degradation occurs. By using feedback from traffic monitoring, the system can initiate switching operations in advance, reducing the effective time loss by anticipating the need for switching rather than reacting after performance has already degraded.

AI summary
Switching a device between bandwidth parts of a channel bandwidth can be managed. A bandwidth part (BWP) management component (BWPMC) can determine characteristics relating to communication rate, quality of service (QoS), or device power based on analysis of data relating to operation of the device, including data relating to service type of a service used by the device or traffic type of data communicated by the device. If heavy traffic is detected, BWPMC can determine whether switching from a smaller BWP to a larger BWP can improve communication rate or QoS. If so, BWPMC can initiate a switching timer. If heavy traffic is still detected when timer has ended, BWPMC can switch from smaller BWP to larger BWP, set another timer, and check again when that timer ends. BWPMC can bypass BWP switching for the device when power saving mode is on or low battery power is detected.
