Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed resource configuration is used for common search space, then system simplicity is maintained, but resource allocation flexibility is reduced
Solution Approach 1:
The patent implements dynamic resource configuration for common search space by allowing the network device to flexibly determine candidate resources based on multiple parameters including cell identity, downlink bandwidth, and frequency domain resource locations. This dynamic approach enables the system to adapt resource allocation to different network conditions and requirements, resolving the contradiction between flexibility and complexity by making the configuration adaptive rather than fixed
Solution Approach 2:
The patent changes the configuration parameters from fixed to variable by introducing multiple determining factors (cell identity, downlink bandwidth, synchronization channel location, broadcast channel location). These parameter changes enable the common search space resources to be dynamically adjusted according to actual network conditions, achieving both flexibility and manageable complexity through parameter-based adaptation
2Productivity
If dynamic resource configuration is implemented, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent improves resource utilization efficiency by changing from static to dynamic parameter configuration. The network device determines candidate resources based on multiple variables including cell identity, downlink bandwidth, and channel locations, allowing the system to optimize resource allocation according to actual network conditions and achieve better productivity
Solution Approach 2:
The patent implements dynamic resource allocation that adapts to changing network conditions. By making the common search space configuration dynamic rather than static, the system can respond to varying traffic demands and network states, improving resource utilization efficiency while managing complexity through structured dynamic determination

AI summary
The present disclosure relates to communication methods and communications apparatus. One example method includes receiving, by a terminal, configuration information sent by a network device, where the configuration information is used to indicate a resource in a plurality of candidate resources of a common search space, and the candidate resources of the common search space are determined based on one or more of a cell identity, downlink bandwidth, a frequency domain resource location of a synchronization channel, and a frequency domain resource location of a broadcast channel, and receiving, by the terminal, common control information on the resource indicated by the configuration information.
