Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple first-type BWPs are used for data transmission in discrete spectrum, then data transmission can be performed on nonconsecutive frequency domain resources, but indication overheads of DCI increase
Solution Approach 1:
The patent merges multiple first-type BWPs into a single second-type BWP that encompasses all discrete frequency domain resources. This consolidation allows the network device to schedule all nonconsecutive frequency resources using one DCI message instead of multiple separate DCI messages, thereby reducing indication overhead while maintaining the capability to transmit data across discrete spectrum portions.
2Productivity
If a second-type BWP is introduced to improve spectrum efficiency in discrete spectrum, then spectrum utilization is improved, but the complexity of determining frequency domain location and parameters increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the frequency domain resources and parameters of the second-type BWP through higher-layer signaling (RRC signaling) before actual data transmission. The network device configures the set of discrete frequency domain resources, their locations, and associated parameters in advance, so that when data transmission occurs, the terminal device can directly use these pre-established configurations without performing complex real-time determinations.
3Adaptability or versatility
If no parameter determining rule is specified for second-type BWP, then the system can support discrete spectrum, but the terminal device cannot determine the frequency domain location and parameter of the second-type BWP
Solution Approach 1:
The patent implements feedback through higher-layer signaling mechanisms where the network device provides explicit parameter determination rules and frequency domain resource configurations to the terminal device. Through RRC signaling and other higher-layer protocols, the network device feeds back the necessary information about the second-type BWP's frequency domain location, resource allocation, and parameters, enabling the terminal device to correctly interpret and use the discrete spectrum resources.
